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, precautions should be taken to minimize exposure. Do not sand or grind brake linings unless suitable local exhaust ventilation equipment is used to prevent excessive asbestos exposure.

• Wear a suitable respirator approved fo...

Brake Linings

Remove both front wheels and inspect the brake discs, calipers and linings. (Wheel bearings should be inspected at this time and repacked if necessary).

Do not get any oil or grease on the linings. It is recommended that both front wheel sets be replaced whenever a respective shoe and lining is worn or damaged. Inspect and, if necessary, replace rear brake linings also.

If the caliper is cracked or fluid leakage through the casting is evident, it must be replaced as a unit.

Brake Roughness

The single and tandem vacuum boosters are self contained vacuum hydraulic power braking units. These are vacuum suspended units that use vacuum and atmospheric pressure for their power.

On gasoline engine vehicles, vacuum is supplied through a fitting in the intake manifold. On diesel engine vehicles, vacuum is supplied through a vacuum pump.

The three basic elements of the booster are the vacuum power chamber, mechanically actuated booster check va...

Brake System Bleed

The RABS II master cylinder and hydraulic control unit must be bled using anti-lock brake adapter tool No. T90P-50-ALA and jumper tool No. T93T-50-ALA, or equivalents. If this procedure is not followed, air will be trapped in the hydraulic control unit and will contribute to improper brake pedal feel.

Bleed system as follows:

• Place bleed/harness switch on bleed adapter tool to bleed position.
• Turn ignition switch to On position. At this point, the red OFF indicator should turn on.
• Push motor button on the adapter down. This starts the pump motor.
• The red OFF indicato...
