Brake Vibration

Owners of 3-, 5- and 6- Series cars (chassis E21, E28, and E24) may notice steering or brake vibration when the brakes are hot when decelerating from freeway speeds. The brake rotors, when checked for lateral run out and thickness variation, are usually within specs. If the front brake pads are designated "Jurid 506" the sources of the vibration could very well be related to excessively hardened pad material. Later brake pads were connected with less hardening and are designated "Jurid 506*". The back of the corrected pad as a * symbol.
