Brake Question
My car is rolling to a stop very roughly when I apply the brakes. With no brakes, the car rolls fine. When brakes applied it almost feels the front wheels are "out of round". If I ease off the pedal slightly it improves somewhat. I am not talking about hard stops. Just stopping in normal situations. Had the car serviced recently and was told pads still had over 60% life. Could this be a warped rotor issue? I've got about 28K miles on the car. Strictly daily driver, no racing.

rotors
There are many posts here about so-called warped rotors. It seems to be a build up of pad material on the rotors from what some say. This causes the rotors to give the car the uneven motion when just barely appling the brakes. If I remember correctly a cleaning of the rotors by a sequence of braking may cure the problem. I'm sure some one more knowedgable than me will respond.

Warped rotor--Thats the first thing I thought of when I read your post. You might be able to jack up the front of the car and watch real close as the rotor spins through the pads and caliper Corvettes are famouse for warped rotors

You have to use the brakes hard to keep it from happening. Long highway trips and easy braking get you the thumping pretty quickly.
Although it behooves you to check the rotors for problems when something like this happens. My 99 Tahoe developed the same type of pulsing then thumping and when I finally got the truck on a lift I found I had to replace the right front rotor since it had a very nice round (about 1 1/2 in in diameter and 1/8 in deep) corrosion hole on the backside of the rotor.
