First thing going on, I just got my rotors, calipers and breakpads changed. So after that is finish I take it out and when pressing on the break it has like a farting noise which my dad thought it was ABS but it seemed to be coming on when it didn't before. So I take out the ABS fuse and it goes away but my car started shifting hard. Next I notice when pressing on the break, there is a clicking noise coming from under my automatic shifter. My car is a 96 A6 Quattro. Please help. Its greatly appreciated.

 

Just a guess -- but I wonder if they messed up one of the ABS sensors when they did the brakes...
