the brakes on my 95 a6q are soft. there seems to be plenty of pad left. the dash lite is on all the time (and drives me nuts). the car seems to stop fine. when the car is just about to stop the front drivers side abs kicks on and it sounds like that brake is farting, even when the road is dry and clean. there is a slight pedal pulse at that piont. any useful hints on this issue would be apperciated.
