1991 Dodge B150 VAN Brake Service (ONLINE REPAIR MANUALS)

The Bendix Anti-Lock 10 Brake System has self diagnosis capability. The self diagnosis cycle begins when the ignition switch is in the ON position. An electrical check is completed on the ABS components such as wheel speed sensors continuity, system continuity and other relay continuity. During this check the Anti-Lock Light will be on for approximately one to two seconds.

The ABS system is constantly monitored by the CAB. If the CAB detects a fault, it can disable the brake system anti-lock function. Depending on the fault the CAB will light either one or both brake system w...

9, 10 & 11 INCH DRUMS

Removal

• Raise and support rear of vehicle, then remove tire and wheel assembly.
• Remove brake drum. If brake lining is dragging on brake drum, back off brake adjustment by rotating adjustment screw. If brake drum is rusted or corroded to axle flange and cannot be removed, lightly tap axle flange to drum mounting surface with a suitable hammer.
• Using brake spring pliers or equivalent, remove primary and secondary shoe return springs, Fig. .
• Remove automatic adjuster cable from anchor plate, then unhook from adjuster lever.
• Remove adjuste...

Except Front Wheel Drive Models

• On models equipped with Rear Wheel Anti-Lock brakes (RWAL), connect one end of a suitable hose to bleeder valve on RWAL hydraulic valve and submerge other end in a glass container partially filled with clean brake fluid.
• Pump brake pedal several times, then hold pedal down firmly.
• With pedal firmly depressed, open bleeder valve until pedal fades to floor, then close bleeder valve.
• Repeat procedure until a continuous flow of brake fluid is released from bleeder valve. Ensure a fluid level is maintained in master cylinder at all times.
• On all mod...

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

This sliding caliper single piston system uses a one or two piece hub and is actuated by the hydraulic system and disc assembly, Fig. . Alignment and positioning of the caliper is achieved by two machined guides or "ways" on the adapter, while caliper retaining clips allow lateral movement of the caliper, Fig. . Outboard pad flanges are used to position and locate the pad on the caliper fingers, Fig. , while the inboard pad is retained by the adapter, Fig. . Braking force applied onto the outboard pad is transferred to the ...

BRAKE WARNING SWITCH

The switch activates a light on the dash panel to indicate that one of the hydraulic systems has failed. There are two basic types of switches. In some earlier models, as pressure falls in one system, the normal pressure of the other system forces the piston to the inoperative side where it contacts the switch terminal, causing the warning lights to illuminate.

On most models, the brake warning switch is of the latching type. If a pressure loss occurs in one side of the system, the piston in the valve is forced toward the failed side where it ...
