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...

Front

Removal

• Raise and support vehicle.
• Remove front wheel and tire assemblies.
• Remove two caliper-to-knuckle attaching bolts, then remove caliper by sliding away from adapter and lifting off rotor, Fig. . Support caliper firmly to prevent weight of caliper from damaging flexible hose.
• Remove outboard pad by prying pad retaining clip over raised area of caliper, then sliding pad down and off of caliper.
• Pull inboard pad away from caliper piston, until springs release from piston.

Installation

• Inspect piston seal for leaks and for ruptures in piston du...

These self contained vacuum hydraulic power braking units are of the vacuum suspended type. They use engine intake manifold vacuum or a vacuum pump along with atmospheric pressure for their power, eliminating the need for a vacuum reservoir. A mechanically operated control valve, with integral vacuum power diaphragms, controls the degree of brake application or release depending on amount of foot pressure applied to...

Master Cylinder

Except Caravan, Town & Country & Voyager

The cylinder body containing the primary and secondary pistons is made of aluminum. The removable fluid reservoir is made of nylon reinforced with glass fiber. The reservoir is the only serviceable component.

The fluid compartments of the nylon reservoir are interconnected to permit fluid level equalization. The equalization feature does not affect circuit separation in the event of a front or rear brake fault. The reservoir compartments will retain enough fluid to operate the functioning hydraulic circuit.

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.

The Controller Anti-Lock Brake (CAB) is used to monitor wheel speeds and modulate...

Manual

• Remove reservoir filler caps and fill reservoir with proper brake fluid.
• If calipers or wheel cylinders were overhauled, open all caliper and wheel cylinder bleed screws.
• Close each bleed screw as fluid starts to drip from them.
• Fill master cylinder reservoir once more before proceeding.
• Attach one end of bleed hose to bleed screw and insert opposite end in glass container partially filled with brake fluid, Fig. . Ensure bleed hose is immersed in fluid.
• Open up bleeder, then have an assistant press down brake pedal.
• Once brake pedal is down, close bleeder. Repeat bleeding unt...
