On vehicles equipped with anti-lock brakes refer to appropriate "Anti-Lock Brakes".

Complaints about power brake operation should be handled as if two separate systems exist. Check for faults in the hydraulic system first. If it is satisfactory, start inspecting the power brake circuit. For a quick check of proper power unit operation, press the brake pedal firmly and then start the engine. The pedal should fall away slightly and less pressure should be needed to maintain the pedal in any position.

Another check begins with installation of a suitable pressure gauge in the brake hydr...

When working on or around brake assemblies, care must be taken to prevent breathing asbestos dust, as many manufacturers incorporate asbestos fibers in the production of brake linings. During routine service operations the amount of asbestos dust from brake lining wear is at a low level, due to a chemical break down during use and a few precautions will minimize exposure. Do not sand or grind brake linings unless suitable local exhaust ventilation equipment is used to prevent excessive asbestos exposure.

The brake shoe and lining assemblies should be replaced if the lining is worn to...

Whenever new brake components are installed in the hydraulic system, it is recommended that the entire hydraulic system be thoroughly flushed with clean brake fluid.

It may sometime become necessary to flush out the system due to the presence of mineral oil, kerosene, gasoline, etc., which will cause swelling of rubber piston cups and valves so they become inoperative. The procedure is as follows:

Flushing is...

Pressure bleeding is recommended for all hydraulic disc brake systems.

The disc brake hydraulic system can be bled manually or with pressure bleeding equipment. The brake pedal will require more pumping and frequent checking of fluid level in master cylinder during bleeding operation.

Do not use brake fluid drained from the hydraulic system when bleeding the brakes. Be sure the disc brake pistons are returned to their normal positions and the shoe and lining assemblies are properly seated. Before driving the vehicle, check brake operation to be sure a firm pedal has been obtain...
