Proportioning Valve

Caravan, Town & Country & Voyager

These models use a proportioning valve and pressure differential switch, or a combination valve. When a premature rear wheel skid is obtained during braking, it may be an indication that fluid pressure to rear brakes is above a desired output and/or a malfunction has occurred within the valve. At this time, the valve unit should be tested as follows:

• Remove actuator assembly adjustment nut, Fig. , then disconnect assembly from valve lever and remove.
• Install gauge and Tee from line pressure set No. C-4007, or equivale...

General Service Precautions

Certain components of the Anti-Lock Brake System (ABS) are not intended to be serviced individually. Attempting to remove, separate or disconnect certain system components may result in personal injury and/or improper system operation. Service components only as directed.

Observe the following general precautions when servicing the system:

• If any welding wo...

Brake Drums

Any time the brake drums are removed for brake service, the braking surface diameter should be checked with a suitable brake drum micrometer at several points to determine if they are within the safe oversize limit stamped on the brake drum outer surface. If the braking surface diameter exceeds specifications, the drum must be replaced. If the braking surface diameter is within specifications, drums should be cleaned and inspected for cracks, scores, deep grooves, taper, out of round and heat spotting. If drums are cracked or heat spotted, they must be replaced. Minor scor...

Brake System Bleed

The anti-lock brake system must be bled any time air enters the hydraulic system. It is important to note that excessive air in the brake system may set a primary pressure diagnostic trouble code in the control module.

Pressure or manual bleeding procedures can be used when bleeding the ABS system after hoses or brake lines have been disconnected. Bleeding the ABS hydraulic system is also necessary after replacement of the hydraulic assembly or wheel brakes. During bleeding procedures, ensure the brake fluid level remains close to the Full mark on the reservoir.

Removal

• Raise vehicle, then remove front wheel.
• On 2WD models, remove outboard brake pad hold down spring, Fig. .
• On all models, disconnect brake hose at caliper and discard fitting washers if worn or damaged.
• Remove caliper slide pins, then lift caliper and brake pads off rotor.
• If necessary, remove brake pads from caliper as outlined under "Brake Pad Service."

Disassemble

• Clean outside of caliper with suitable solvent.
• Drain fluid from caliper and place clean shop cloths in caliper opposite piston.
• Slowly apply compressed air to caliper inlet port until piston moves out of bore. Do not "b... "

Rear Wheel Anti-Lock (RWAL) Brake System

Refer to "Wiring Diagrams" in "Vehicle Systems" to aid diagnosis

RWAL system malfunctions are indicated by a warning lamp on the instrument cluster. If such a malfunction occurs, proceed as follows:

• Inspect brake fluid level and correct as necessary.
• Visually inspect ABS hydraulic and electrical connections and correct as necessary.
• If hydraulic system leaks or weak or corroded electrical connections are not evident, road test vehicle to inspect vehicle for driveability conditions such as low or spongy pedal, brake pulling or grabbing.
• Ensure parki...
