What is TrueBrake?

TrueBrake upgrades your Logitech G25/G27/G29/G920/G923 brake pedal to gives a positive and realistic feel. You feel the load not the small pedal movements. TrueBrake fits perfectly in your Logitech pedal set and all at a reasonable cost. It is the most appropriate and cost effective brake pedal mod available for your Logitech brake pedal.

What does TrueBrake do to my Brake Pedal?

  • Changes your relationship with the brake pedal to a load based sensation
  • Increases the load required to reach full braking
  • Reduces the amount of brake pedal travel to a few millimetres


What’s inside TrueBrake?

  • Cylinder and body: CNC machined 6061-T6 aluminium
  • Piston: Has maximum of 4mm of travel inside the cylinder
  • Main Spring: Heavy duty spring resists the movement of the piston
  • Circlip: Retains the piston in the cylinder
  • Linear Motion Potentiometer: High quality component that detects movement of the piston

3 Stage Load Curve:

  1. When the brake pedal is pressed, the return spring compresses which in turn applies a small load on the TrueBrake piston.
  2. As the brake pedal is pressed harder it engages with the polyurethane transition buffer and the load on the piston quickly increases.
  3. The brake pedal is fully engaged with the TrueBrake piston and TrueBrake main spring.

The small movements of the TrueBrake piston are detected by the linear motion potentiometer which is connected in place of the stock Logitech potentiometer.

Engineering Quality

This unique and quality engineered solution has been rigorously tested and perfected.  All the components are housed in a 6061-T6 aluminium body and cylinder, CNC machined by AXC and designed to fit perfectly inside the Logitech pedal assembly. The end result is a robust and reliable pedal where the braking control is about pedal load rather than pedal travel. Just like a brake pedal should be!

Is TrueBrake a load cell?

We consider TrueBrake an “Electromechanical Load Cell” or a “Potentiometer Based Load Cell”.  Be clear that TrueBrake is not a Strain Gauge Load Cell. Strain Gauge Load Cells use an electrical strain gauge to measure the small bending of a spring element, which is often a metal beam. Using TrueBrake in your Logitech pedals gives similar end results as using a Strain Gauge Load Cell but at a much more affordable price.

Does TrueBrake measure load?

Yes.  The load compresses the internal heavy duty spring and that small movement is detected by the linear motion potentiometer.

Does a potentiometer measure load?

No. We would not claim that.

Does a potentiometer and a spring measure load?

When combined as a system, yes they do.  It’s basic high school level physics.

Can I return my TrueBrake if I don’t like it?

In the unlikely event that you are disappointed by your TrueBrake (within 30 days of you receiving it) you can return it for a refund.

Easy Installation

No permanent modifications are necessary to your pedals. TrueBrake connects in place of the stock Logitech brake potentiometer. No drilling, cutting or soldering required. TrueBrake can be installed using simple tools. You can easily remove TrueBrake and return your Logitech pedals to how they came from the factory.

Whats in the TrueBrake box?

  • 1 TrueBrake Unit
  • 1 Pedal Return Spring
  • 4 sizes of Buffers to adjust pedal free play.


TrueBrake comes with 12 Month Warranty from date of purchase. The TrueBrake unit must not be disassembled or modified by the customer otherwise warranty is void.

  1. Andrew (verified owner)

    This mod was very easy to fit and the quality is first rate. Initially I wondered whether I had made the right decision with this as I was understeering everywhere and couldn’t get close to my old TT times on F12020. After a few days (and it was days or me) of getting used to it however I found I was beating my best (and already pretty good) TT times by roughly half a second, and crucially I was consistently closer to my best times all the time. I have tried to analyse what had changed for me and the best way to describe the change was that once I lost my old ‘muscle memory’ I found that I could brake more consistently through the first phase of a corner and (finally) I had more control of trail-braking coming out of a corner. In my first league race since fitting it I qualified 3 or 4 places higher than I normally would and finished the race a couple of places higher whilst not picking up any penalties. This is a great upgrade at an affordable price – and as long as you are prepared to put some time in to “re learn” your braking style you will be quicker and more consistent.

  2. Josh (verified owner)

    The quality of this brake is amazing. You can tell a lot of time is put in to these. I play mostly dirt rally 2.0 and Iracing with a g27 on oculus rift s. I’ve done a lot of mods to try and add some realism to my sim setup but this break has by far added the most immersion and realistic feeling at such a good price too. I would expect to pay $100+ for something like this. This is the first thing anyone thinking about upgrading their g27 or similar pedal setup should do to add immersion/realism, get faster lap times or whatever. I cannot recommend more highly!!

  3. Tidders

    Oh my god what an amazing bit of kit this is, i was putting money aside for a high end set of pedals, but this has stopped that dead. gives amazing feel and consistency is now bang on. 10/10

  4. USCTrojan4JC (verified owner)

    I installed the TrueBrake mod for my Logitech G27 pedals a few days ago…and wow! This is a great mod!

    At first, I installed the second-largest buffer thinking I didn’t want much soft pedal travel before the brakes engaged more significantly. I initially was going to put in the largest one and then decided on the second-largest one before I closed the pedal assembly. I depressed the pedal a few times with both my right and left foot to see how it would feel with right foot- and left foot-braking. I thought the force needed was way too much for me to use well, but I made the mistake of not trying it in one of the sims I like to play (rFactor 2, Automobilista (CART Extreme mod), iRacing).

    I opened the pedals back up and put the smallest buffer in. I fired iRacing up and drove the Global Mazda MX-5 Cup very briefly. The amount of force needed to really engage the brakes was okay, but I didn’t like the greater initial travel before the buffer was contacted.

    So I opened the pedals back up again and put the second-largest buffer back in. I went back into iRacing and turned did a short 10-lap race in a Global Mazda MX-5 Cup car on the Charlotte roval and some practice laps at floor mat raceway in the Chevrolet Corvette C8.R. I then went into Automobilista and drove some laps in the CART Extreme mod in a 1998 Penske PC27 at Road America.

    The braking force needed to brake consistency is really nice. In the Automobilista CART Extreme mod, not locking up the brakes was hard to avoid with the stock Logitech brake pedal spring and potentiometer combo. With this mod, it is a lot easier to consistently threshold brake without locking the brakes up and the amount of force required feels much more realistic.

    I use my Logitech G27 on a desk. I have a box with weights behind my pedal assembly that sits between the pedal assembly and the room’s wall. I have heavy boxes placed behind my desk chair (Sparco racing seat on an office chair base) that prevent my seat from moving around when I’m braking. It is essential that both your pedal assembly and seat are completely secured if you are going to use this mod.

    Simply an awesome product. Installation was super easy. I have been using it for a couple of weeks now and it works smoothly without any problems. I needed some time to get used to it but when you do it’s such a nice feeling. The only thing that not really bothers me, but would be nice, is to have a wider range of buffers. I’m using the smallest one and I would like to have a bit more of the “dead zone” on the pedal. I think that they should keep the same number of the buffers that you get with the product, just that they would make a bigger difference between them. Otherwise, this is still a great product, totally worth its money. I would recommend this to everyone that wants that little more realistic experience and overall more consistent driving experience.

  6. Anders (verified owner)

    I just received my Truebrake. Installation is easy, if you have tried modding the brakes before (G29).
    I went for smallest buffer.
    Result is amazing. Withing 2 laps I was way more consistent, within 10 laps I was shaving of a full second on lap times (iracing) and being just amazingly consistent.
    This is a game changer for me. My laps in GT cars were just so much smoother.
    Highly recommended if you don’t have space and money to go to real loadcell brakes

  7. David Parisio (verified owner)

    Update, installed TrueBrake Mod
    G29 on Ps4. I exclusively play DirtRally2.0. I might go back and give WRC 8 another chance now.

    Pedal feel and sensitivity are amazing. Completely different pedal feel and I’ve already shaved seconds off my shakedown times from earlier today with the stock set up.

    Install was super easy and straightforward, definitely worth the money.

    Thanks Rob and whoever else has helped you with this amazing product.

  8. Damien Davies (verified owner)

    The wait was worth it, what an upgrade. Just knocked 1.4 seconds off my Melbourne time trial lap time. Was it a fluke? Nope, next lap within 2 tenths, and the next lap and so on. I cant believe how much i was locking up, always play no ABS, and coming to this its sooo much easier to judge and feel, and you really get the most out of your braking. For the record im a desk player (no rig) and use castor cups for my chair wheels. Works absolutely fine (my biggest worry). Ok, it has made me want a rig at some point, because i know it would be better, but if ur like me and stuck with a desk, and worried about the pressure needed on a desk set up, dont, love it. Game changer!!!

  9. Buddy (verified owner)

    Amazing Upgrade for the G29 Brake Pedal. I tried many modifications but nothing works so good like this true brake mod.
    After 2 hours of testing I found not many time on a hot lap, maybe only half a second, but I am a way more consistent in a hole race and can repeat the fast laps much more easy.
    Change the brake spring to clutch and the clutch to Throttle is very nice too. I use some 3d printed Distance mods for the springs too, so they are a little bit harder. Now I can dose the throttle better and together with the very good brake I can progress much better. So I think I found the 1,5 second that I loose to the top drivers in the next weeks.
    Even heal and toe is much better too.
    So thank you very much for the development of this brake mod for that nice price.

  10. Brandon (verified owner)

    Unlike others, I was entirely used to these brakes after the first corner. A+

    Also as others have suggested, switching oem brake spring to clutch, and clutch spring to Accel is totally worth it.

  11. Deniss Kapins (verified owner)

    This is a game changer for Logitech pedals. Installation was easy, hardest part for me was taking wires off stock potentiometer with my fingers, rest is a cake walk. At first I struggled to brake, cause leg was used to pedal travel, after few hours I couldn’t imagine a better upgrade for g29, I wish I haven’t spend so much money before on other brake pedal enhancements. I applaud you Sir Rob!

    I also suggest if you’re into CNC, please start producing Custom Logitech Tilton styled pedal faceplates, a cosmetic add-on but so much needed!

  12. Ryan Gentzler (verified owner)

    I was angry when I finally received this…..because it’s so darn good, I wish I had gotten it years ago. I used the largest stopper in the kit and there is almost 0 detectable pedal movement! It feels like a load cell. My braking is now more precise, and accurate. Easily worth the cost (which is next to nothing compared to load cell mods) and the wait for backordered parts. Get the TrueBrake!

  13. andyhill007 (verified owner)

    Ok, this is my second review of this pedal, i reviewed after about 5/6 hours of use and was somewhat slower in overall lap times and consistency. At the time, after waiting around 7/8 weeks for this mod to come, i was very frustrated and left a heat of the moment review. Now, all credit to Rob, he e-mailed me and without question said that he would give me a full refund as it was the first bad review he had. By this time, i had calmed down somewhat and gave the pedal more time. So glad i did, i am fully up to speed now and consistency is there. The only reason i have not given it 5 stars is the fact that you have to take the pedals apart again if you don`t like the feel of the rubber stopper you have fitted, there are four of these to choose from varying in size. Not sure if some form of quick release could of been designed but i guess its about keeping costs down. The quality of the product does not come into question, its top draw. If you buy this mod, don`t be a hot head like me, it just took me longer to adjust to it, you may need longer as well.

  14. Gregory Hlopak (verified owner)

    It is absolutely wonderful, very impressed. It is night and day. I have already broke my lap records but whats more is consistency in lap times!!! Thank you so much. Great company. Highly, highly, highly recommended. You will not regret it one bit. Cheers

  15. Dale (verified owner)

    Absolutely amazing piece of kit! Easy to install in my G29 pedals. I mainly play Dirt Rally 2.0 and instantly saw my stage times faster, especially in older cars that don’t have modern brakes, as it made it easier to trail brake and not lock wheels under heavy braking! Can’t believe it was so cheap to be honest, when you compare how much fanatec and thrust master pedals with loadcells cost. 10/10!

  16. Anthony Grantham

    An excellent company to deal with and a truly superb product. It’s clearly well made and works fantastically well. I’d recommend without hesitation!

  17. Bruce (verified owner)

    Absolutely fantastic, these really are a game changer.
    This is a delayed review, as I have been waiting for my week off to install them and get some time using them.
    They look great, amazing quality, a straight forward installation and they work.
    I’ve come from ETS, ATS hence wanting the change of pedal on my G27’s.
    My sim times and consistency have been transformed by this mod.
    Obviously they take a little time to get used to, but as soon as you do, the difference is night and day. While installing these I swapped the spring from the clutch into the accelerator pedal. I’m now so pleased with the difference, I hope to change wheel, but will still use the G27 pedal set.
    My advice, if you’re thinking of buying these, just go ahead and get them.

  18. Keith (verified owner)

    Worth the wait and the cost. It’s transformed my old G27 pedals. I fitted the Truebrake, then put the old brake spring into the clutch, making it feel more like a proper car clutch; then I moved the clutch spring into the accelerator, which improved the stiffness. over the original.

    A fair bit of time and practice is needed to find the best brake sensitivity level and learn the new brake pressures and braking points.

    Also, although it’s not essential, it is worth trying the different buffer sizes that come with the Truebrake (even if it is a pain constantly dismantling and rebuilding the pedals) – there is a noticeable difference between the 4 buffers. The smallest one gives more spring movement before hitting the ‘piston’, so it actually engages low brake pressure more easily.
    The longest buffer leaves no free play, so it takes a bit more force to apply small/medium/full pressure, but in a very short travel.
    It’s personal preference whether you want the full range of brake application in the short travel, or a more noticeable difference in the pressure range by using the small buffer.

    This is definitely an upgrade over the original spring, and I would not want to go back.

  19. John z (verified owner)

    Receive my true break today after finding the right set up this little device is awesome feels just like power Disc brakes on my Mustang Definitely recommend this product well worth the wait thanks

  20. Daniel (verified owner)

    Great upgrade and at this price it’s the best that is available for the Logitech brake pedal.
    It’s a very well built unit, simple to install and is plug and play.
    I’ve had mine for quite a while now and it has made braking much better, being able to trail brake and modulate the pressure through the corner. It really is a game changer for £54.99, I’ve tried GTEYE spring upgrades and others that are £20 – £25 that aren’t that much better than stock really. Thanks

  21. Alex (verified owner)

    Fantastic value, utterly transforms braking.

    I went from guessing how much brake to apply to easily modulating on the edge of traction.
    Personally I recommend moving the old brake and clutch springs between the clutch and accelerator for overall stiffer pedals.
    This mod has knocked seconds off my laptimes and greatly aided consistency and confidence.

    Highly recommended.

  22. Khalid (verified owner)

    A must have upgrade to the logitech pedals and outstanding support. A high quality built that is easy to install. the firmer brake takes some time to get used to, but once you get the hang of it the laptimes get more consistent and easier to threshold and trail braking. It was near impossible to drive without ABS earlier and be consistent.
    Note: I had to set the brake gamma to 1.0 as its is very linear.

  23. Andre (verified owner)

    Great upgrade for a reasonable price. Easy and well described installation. Well manufactured.
    Took me a few hours to get used to it and i had to relearn braking for every car (iRacing), but consistency and lap times started to improve greatly. Trail and threshold braking is much easier now and controlable for cars without ABS.
    The only drawback (due to my setup) is that my G29 pedals set moves slightly on my hardwood floor during long races because of the higher forces needed for 70-100% braking.
    Highly recommended!

    Hello Folks….
    I spent lot of euro’s on brake mods for my g27 pedals.
    Nexim springs, secondary die springs, 3d rap mod….
    Wish this one was available earlier.
    This is the best most affordable brake mod on the market. This brings the G27, 25, 29 at the same level as a loadcell mod, without the hassle.
    Professional product, installs in ten minutes ( ok, after 15 times modding my pedals I know how to open them).
    Good, predictable braking, strong but not rock hard pedal feel.
    Look no further!! This is the best upgrade to make a affordable steering wheel kit, much better!!!!!
    Congrats on this product!!!

    Now some steering wheel adapter plates???
    Best regards!!

  25. Patrick Schneider

    Totally worth the money. At First i had my problems to get used to the pressure, but trailbraking is now easier. Doesn’t make me really faster because i am not that good, but constancy is overall better now.

  26. Lindell Harry (verified owner)

    Been toying with the idea of getting one for a while and finally bit the bullet. If you have a compatible logitech pedal set it’s a no brainer. Excellent build quality and way more predictable braking = faster more consistent times.

    Wish they did more mods tbh.

  27. Alessandro Lamanna

    I rarely write reviews, but I just installed this mod and felt like I needed to put out my two cents. I researched both this and the loadcell mod and I am more than happy with my choice. The pedal feel is a night and day difference with a short, progressively stiff travel. If you are completely used to your g29 brake setup, you will initially regret your purchase. “What the hell, this pedal feels weird!” About 10 laps in, I was like “this is awesome!” Once you get used the amount of pressure needed for 100%, 50% and 5% your trail braking will be improved and you will carry more speed through the corners. I was able to match my best lap times that took numerous attempts in GTsport time trial within the first 10 laps and with a little more time will easily beat it easily. You will also be more consistent lap after lap. Easy install and extremely well built. Highly recommend. No need to spend more money on a loadcell mod when this works beautifully!

  28. Rebel_488 (verified owner)

    Excellent piece of kit and really upgrades the pedal to something you will love. It takes a short time to get used to but you will quickly adapt your braking style to something very like an actual race car, accuracy becomes much easier, trail braking becomes instinctual. Don’t hesitate this is a bargain at the price. I preferred the 3mil option with less travel. Easy to fit.

  29. James Taylor

    Easy to install. Plug & play.
    Used on Gran Turismo Sport (PS4).
    I am very impressed with the brake feel and firmness, it’s very realistic and comparable to a real car!
    Brake pedal initially moves about 3mm then brake pressure is both felt through the pedal and applied to the vehicle. More pressure, (applied through a further 5mm of pedal travel) gives the vehicle between 1 and 100% in-game brake force.
    It takes real effort to reach 100% brake pressure, but nothing over the top. Heel and toe is so much better with the mod. More control is possible, and blipping the throttle whilst on the brakes is easier as the brake pedal depresses a much reduced distance. Added much needed realism to the brake. Very happy.

    I used to have a rubber mod and I was quite satisfied with it comparing to the default brake. But now braking feels even more detailed and progressive. Trailbraking comes more naturally. The run of the pedal is very reduced and it feels like pushing a brick. I installed the hard buffer and got used to it after a very few laps. It may not be a real load cell but the feeling is the closest thing you can get. My laps definitely got more consistent.
    Truebrake is great value for its price: good performances, plug’n play installation, great building quality (metal, metal, metal).
    Definitely a bargain for Logitech users

    To review this item in one word: WAUW!
    I just installed the Truebrake system in my Logitech G29, and I was surprised how easy the install was!!
    Also the instructions were ery clear to follow!

    It drives, and feels so much better then the stock Logitech hardware.

    AXC-SIM, keep up the good work.

    You have made me very happy indeed.
