Brake Pedal Sticking On? Logitech G29 Brake Fix [+ Video]

Is your Logitech G29 brake pedal sticking? Mine was, and this is how I fixed it. I’ve also included 2 useful YouTube videos, including one for G25/G27 users.

So last night in F1 2021, my Logitech G29 brake pedal kept sticking on. Nothing about it felt odd, it was operating smoothly. But, it was applying the brake at random.

It was sticking on straights, and sometimes sticking on after I’d applied it. Annoying!

Hitting it on and off freed it up, but there’s little point racing when you’re braking on a straight.

There’s two potential causes here:

  • The wiring is shot
  • Dust is covering the potentiometers

In my case, it was dust. As you press on the pedals, it drags dust into the pedal housing. Over time, that builds up and causes issues.

I found a couple of useful videos. This one’s actually the G25/G27 wheel & pedal setup, but the principle is the same.

And, if you need visuals of the actual G29 brake pedal being taken apart, this one is pretty-good.

They’re useful, but long-winded. So, if you’d rather just get straight to it…

How To Fix A G29 Brake Pedal

What You’ll Need

  • Allen keys
  • Phillips screwdriver
  • 10mm spanner (or wrench…whatever)
  • Lube (WD40, GT85 etc)

What You Need To Do

  1. Remove The Top Of The Pedals

You’ll need a small Allen key to remove the TOP of the pedals. You’ll need to remove all three.

This allows you to lift the casing off easily, so you can work on fixing the brake.

  1. Remove 26 Screws From The Brake Housing

There are 26 screws in total. If you don’t have 26 in your hand, and the housing doesn’t come off, you’ve missed some.

  1. Take Apart The Brake Assembly

You’ll see a 10mm nut on the brake assembly, you’ll need to remove it to take the brake apart.

Note: As the pedal is spring loaded, you may need to put pressure on/off the pedal to free the bolt.


Clean everything, especially the little cog/potentiometer. Then, lube the potentiometer a tiny bit, this will help to stop dust sticking.

This is the fix.

  1. Put It All Back Together

Put the nut back on the pedal assembly, the 26 screws back in etc.

Make sure the cable is routed correctly BEFORE you tighten up the 26 screws.

  1. Race

  1. So recently I have found another reason it sticks after cleaning it: the plastic is broken.

    1st time it broke, i cleaned it. 2nd time, was shortly after cleaning it, so it shouldn’t have gotten too dusty there. After many hours of trying to figure it out and giving up a few times, I’ve found it: the plastic rod sticking from the potentiometer must have cracked somewhere along it due to all the forces going through it as I was able to slightly wobble it (checked the clutch and the gas but neither wobbled). Having the windows calibration window up and pressing down on it showed it sticking sometimes.

    -Fix 1: Stop the wobble.
    prop the far end of the rod up so it doesn’t have the chance to move, I did this with some hot glue, tape and… pennies. Pennies because they are useless normally yet you need something that wont compress when it is pressed, and I didn’t have anything similar.

    3rd time was a nightmare, again after banging my head for hours I noticed that the 1st 2 gear teeth were broken. This can be fixed by realigning the teeth so that only not broken ones are used, however this reduces the already short travel of the g29 brake. This was a no bueno from me.

    -Fix 2: Fix the gear teeth.
    I was lucky enough to have been gotten a 3d pen for christmas and I’ve finally found a reason to use it XD. Took about an hour for me to add plastic in the areas and then file it back to look like the rest of the teeth, but at this point you might want to say “time for an upgrade” since you’ve probably already had this thing for multiple years. Sadly there isn’t a different way to fix the broken gears, and you may complain to logitech for using plastic for brake pedal gears (though they’ll just say thats under normal wear and refuse to compensate you).

    After all, this is the best of the cheap, but its still cheap. Good luck, hope this helps somebody. (Though I rarely check my email, if you want a pic or tips to fix it with a 3d pen I can tell you how I did it, but I’m not saying its the best method)
