Dear sifu,My E36 brake will had serious vibration when drive in raining (when i do emergency brake). Sometime even worst that i can stop the car. Any sifu know what happen to my car?? Oh ya, somtime the ABS light will on for nothing, but after i switch off and turn on the engine again, the light disappear. Is that becase of the faulty of ABS sensor??? How much it cost??Thanks!!!
