Master Cylinder/Power Booster Test

• Start engine and inspect booster vacuum hose connections for leaks.
• Stop engine and shift transmission into neutral.
• Pump brake pedal until all vacuum reserve in booster is depleted.
• Press and hold brake pedal under light foot pressure. Pedal should hold firm. If it falls away master cylinder is faulty.
• Start engine and note pedal action. Pedal should fall away slightly under light foot pressure, then hold firm.
• If no pedal action is felt, the power booster, vacuum supply or vacuum check valve are faulty. Proceed to "Power Booster Vacuum Test."
• If p...

Brake Lines & Linings

Remove one of the front wheels and inspect the brake disc, caliper and linings. The wheel bearings should be inspected at this time and repacked if required.

Do not get any oil or grease on the linings. It is recommended that both front wheel sets be replaced whenever a respective pad is worn or damaged. Inspect and, if required, 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.

The most common cause of brake chatter on disc brakes is a variation in thickness of ...

When wheel slip is detected during a brake application, the ABS enters anti-lock mode. During anti-lock braking, hydraulic pressure in the individual wheel circuits is controlled to prevent any wheel from slipping. A separate hydraulic line and specific solenoid valves are provided for each wheel. The ABS can decrease, hold, or increase hydraulic pressure to each wheel brake. The ABS cannot, however, increase hydraulic pressure above the amount which is transmitted by the master cylinder during braking.

During anti-lock braking, a series of rapid pulsations is felt in the brake pedal...
