Well, I finished putting my new mk3 drums on the rabbit, bled the whole system AGAIN with ATE superblue, and the pedal doesn't feel any stiffer. I am sure it stops better, but I wouldn't know....there is no engine in it haha On the other hand, got ahold of a new mk3 MC and put it on my mk2 jetta (only 9.4's and 180mm drums, ironically) and it feels great! There is very little travel in the pedal to make it WORK!
Pros: feels great, little travel
Cons: pedal doesn't feel stiffer
Vehicle:
Volkswagen Jetta
