I have an 85 Chevy Caprice which began pulling to the left a little during braking, about 4 months ago. It hasn't gpotten any worse since then. It only pulls during the first 2 or 3 stops, then brakes in a straight line, until I don't use the brakes for about 10 minutes, then it will pull again, but only for the first 2 or 3 brakings, then all is well again until I am completely off the brakes for 10 minutes or longer.
It's as though the cold brakes pull, but the warmed up brakes do not pull.
All 4 pads are full, and only have about 2,000 miles on them. When I put the new pads in, a year ago, I also replaced the front left rotor, and repacked the front left wheel bearings. The car pulled to the RIGHT immediately after that work, but cleared up after a while, by itself, and was braking straight for a few months, then started this pulling to the left. I did not turn the new rotor.
ANy ideas welcomed !
