• On models equipped with Rear Wheel Anti-Lock brakes (RWAL), connect one end of a suitable hose to bleeder valve on RWAL hydraulic valve and submerge other end in a glass container partially filled with clean brake fluid.
• Pump brake pedal several times, then hold pedal down firmly.
• With pedal firmly depressed, open bleeder valve until pedal fades to floor, then close bleeder valve.
• Repeat procedure until a continuous flow of brake fluid is released from bleeder valve. Ensure a fluid level is maintained in master cylinder at all times.
• On all mod...

This sliding caliper single piston system uses a one or two piece hub and is actuated by the hydraulic system and disc assembly, Fig. . Alignment and positioning of the caliper is achieved by two machined guides or "ways" on the adapter, while caliper retaining clips allow lateral movement of the caliper, Fig. . Outboard pad flanges are used to position and locate the pad on the caliper fingers, Fig. , while the inboard pad is retained by the adapter, Fig. . Braking force applied onto the outboard pad is transferred to the ...

HYDRAULIC VALVE, REPLACE

• Disconnect battery ground cable.
• Raise and support vehicle.
• Disconnect electrical connectors from valve, Figs. and .
• Disconnect brake lines from hydraulic valve.
• Remove hydraulic valve attaching screws and the valve.
• Reverse procedure to install, noting the following:

The Bendix Anti-Lock 10 Brake System has self diagnosis capability. The self diagnosis cycle begins when the ignition switch is in the ON position. An electrical check is completed on the ABS components such as wheel speed sensors continuity, system continuity and other relay continuity. During this check the Anti-Lock Light will be on for approximately one to two seconds.

The ABS system is constantly monitored by the CAB. If the CAB detects a fault, it can disable the brake system anti-lock function. Depending on the fault the CAB will light either one or both brake system w...

The electronic control module in this system has the capability of generating and storing fault codes. If a fault is detected, the system will illuminate the amber anti-lock warning lamp and set a fault code. When a fault code is set, the amber anti-lock warning lamp will illuminate. In most cases, the red brake warning lamp will also light.

When a problem in the system is suspected, preliminary diagnosis should begin with a fluid level check and a visual inspection of the electrical and hydraulic connections in the system. If obvious faults are not found, a road test will he...
