CAUTION
Older brake pads or shoes may contain asbestos, which has been determined to be cancer causing agent. Never clean the brake surfaces with compressed air! Avoid inhaling any dust from any brake surface! When cleaning brake surfaces, use a commercially available brake cleaning fluid.

TESTING



To properly diagnose the hydraulic valve, a scan tool capable of reading ABS codes (DRB, DRB-II, DRB-III or equivalent) is necessary. Because of the complexity of the ABS system and the importance of correct system functioning, it is recommended to have a qualified automotive technician test the system if any problems have been detected.
