m3 e92 with ap racing brake
I installed Ap racing brake kit before track day, it works perfectly on the track, but I found noise problem after track.
I totally understand and accept the brake pad will squeal when I slightly brake it under low speed , but now the problem is , after I make complete stop, release brake and start moving, I can feel the front pad still rub the roter make the entire car under high frequency vibration, the vibration feels exactly like the noises when you push a table on a concrete surface.
Usually the vibration will goes away when the speed is over 10 mph (keep wheel straight) , and will come out when I make turns around 25-30 mph after brake(on the ramp to exit freeway or make turns at intersection) .
Any one has experience on this?? is this normal??
