1995 BMW 325i Question: noise when braking
Sounds like the ABS system is activating, causing the noise. Have the ABS system checked, if the light is coming on you may have a fault stored in the ABS Control Module that could help determine the cause of this problem. This can sometimes be caused by dirty ABS Wheel Speed Sensors. - munkyrench
