Hello all,
Sorry for recovering this post, but I would like to know how was the final behavior of the yours brakes upgarding.
I am from Spain and i am looking for information about the brake upgrading for my A6 biti competition. I bought and installed the rs6 2017 brake system in my car. All parts are plug and play, but ....... always there are any but.
The brake pedal now is smoother that the original and the pedal goes donw more too.
Other problem is, when i push the brake pedal energically (like in an one emergency), the car goes firts to the letf side and immediately return to the center, in summary, the car has a uneven braking. However, if i push the pedal no energically at the beginning the braking is stable and very hard.
I know that the brake master cilinder is the same in my car and in the RS6. The brake booster is the same too, the pipe is the same and the only differencies that I have found it is the ABS moduletor.
I have bleed the system 4 times in the oficial audi garage, I have reviewed and rebuilded the calipers, I have reviwed the discs (they are perfect), but the problem continues there.
I have changed againg the original A6 biti competition brake system and the car run perfectly.
Someone who has made this change had the same problem ?.
I am desperate because i read similar changes in the same car and nobody says anything about.
Sorry for my bad English.
Regards
Alberto
