I recently bought a 2005 Audi A4 1.8T quattro. I have had a problem with my brakes. The car stops fine, no problems there. The problem is the front (I think) brakes vibrate or thud when I brake. It doesn't happen all the time but it seems to most frequently happen when I brake really hard or when I do long distance braking. I'm no mechanic, but it seems to me that something is misaligned or warped. I talked to and showed a friend that is very good with cars, and he told me that its the ABS but I've driven several other Audi's of the same year, and I never had that problem with those cars. Any ideas or solutions to the problem would be very helpful.
