light is NOT on. I don't think I'm going to wait for it to come on at all. I'll replace them tomorrow, since it will be a nice day and all. Either my brake warning system is shot or the rear doesn't have one.

Both of front and rear brakes were replaced with new rotors at 55k miles, now it's almost 92k miles. <a href="https://www.audiworld.com/forums/showthread.php?t=2849517">The front brakes went out at 77k miles</a> and I've been waiting for the warning light. Just remembered them yesterday.

Cheers,

Make sure you read up on a few threads on resetting the rear brakes. There is a glitch (undocumented feature) with the VCDS software or the brake electronics so that you need to adapt the thickness of the pads several times. See post here

BTW, did you get your PTC? I have a few laying around, let me know if you need them, come by the office, I'll give them to you.

The procedure seems to be simple.

I'm going to experiment replacing epb brakes without VCDS... :-) even though I have both $350 and $30 ones.

Thanks again,

Exactly how do you plan on doing this? You can't back the motor off without commanding it.

Actually it is very easy to do in a more than one way. One would be to unscrew motor and retract piston manually. Next would be to screw the piston in watching not to damage the seal. So each side in a different way. Of course there is VCDS way too.

I thought about that, but I think the risk of damaging something, especially a seal, makes just doing it through VCDS the only real practical way of doing this.

I need to finish the job quickly, it's done, the right way, no experimenting anything. Everything works perfectly as designed. Video will be available very soon.
