The nuts and bolts that attach the rear brake adaptor to the axle housing flange can loosen and eventually separate. If one or more of the nuts come off the bolts, damage to the parking brake assembly or to the antilock brake system (ABS) sensor and sensor ring (if so equipped) will occur. If all four nuts on one end of the axle come off the bolts, damage to the brake hydraulic line or the parking brake cable can occur.
Dealers will inspect and, if needed, install new bolts. If any of the fasteners are disconnected, the parking brake and ABS components will be inspected and serviced.
