Brakes
The vehicles covered by this manual are equipped with hydraulically operated front and rear brake systems. The front and rear brakes are disc type. Both the front and rear brakes are self adjusting; disc brakes automatically compensate for pad wear.
Hydraulic system
The hydraulic system consists of two separate circuits. The master cylinder has separate reservoirs for the two circuits, and, in the event of a leak or failure in one hydraulic circuit, the other circuit will remain operative.
Power brake booster
The power brake booster on models with a gasoline engine uses engine manifold vacuum to provide assistance to the brakes. It is mounted on the firewall in the engine compartment, directly behind the master cylinder.
Diesel engines, which have no manifold vacuum, are equipped with a hydraulic brake booster that relies on pressure provided by the power steering pump.
Parking brake
The parking brake mechanically operates the rear brakes only. The parking brake cables actuate a pair of parking brake shoes mounted inside the drum (hub) portion of each rear brake disc.
Service
After completing any operation involving disassembly of any part of the brake system, always test drive the vehicle to check for proper braking performance before resuming normal driving. When testing the brakes, perform the tests on a clean, dry, flat surface. Conditions other than these can lead to inaccurate test results.
Test the brakes at various speeds with both light and heavy pedal pressure. The vehicle should stop evenly without pulling to one side or the other.
Tires, vehicle load and wheel alignment are factors which also affect braking performance.
Precautions
There are some general cautions and warnings involving the brake system on this vehicle:
a) Use only brake fluid conforming to DOT 3 or 4 specifications.
b) The brake pads and linings contain fibers which are hazardous to your health if inhaled. Whenever you work on brake system components, clean all parts with brake system cleaner. Do not allow the fine dust to become airborne. Also, wear an approved filtering mask.
c) Safety should be paramount whenever any servicing of the brake components is performed. Do not use parts or fasteners which are not in perfect condition, and be sure that all clearances and torque specifications are adhered to. If you are at all unsure about a certain procedure, seek professional advice. Upon completion of any brake system work, test the brakes carefully in a controlled area before putting the vehicle into normal service. If a problem is suspected in the brake system, don’t drive the vehicle until it’s fixed.
