Vehicle: 1994 Buick Regal Custom 3.1 V6 GAS

SYSTEM

The function of the Anti-Lock Brake System (ABS) is to minimize wheel lockup during heavy braking on most road surfaces. The system performs this function by monitoring wheel speed and controlling the brake fluid pressure to each front wheel and both rear wheels during braking. This allows the driver to retain directional stability and better steering capability.

SYSTEM COMPONENTS

Refer to Fig. for system component locations.

ELECTRONIC CONTROL UNIT (ECU)

The ECU located on the rear righthand side of the engine compartment uses various inputs to control ABS operation and provide ...

System Testing

This system contains a sophisticated onboard diagnostics that can by accessed with a bidirectional "SCAN" tool. To properly diagnose the ABS system a GM TECH 1 bidirectional scan tool or suitable equivalent is necessary. The scan tool can be used to identify system faults as specifically as possible including whether or not the fault is intermittent. The scan tool can also be used to monitor the input and output signals of the ABS Module, manually control system components and perform automated functional tests. Using the scan tool, allows for accurate fault conf...

BRAKE SERVICE PROCEDURES FOR 1994 Buick Regal AUTOMOBILES

Includes anti-lock brakes, disc, drum, power and hydraulic brake services diagnostics and procedures for domestic and imported 1994 Buick Regal cars and light trucks from 1990+.

Hydraulic Brake Systems -> Description -> BRAKE DISTRIBUTION VALVE & SWITCH -> BRAKE WARNING LAMP SWITCHES -> COMBINATION VALVE -> COMPONENT DESCRIPTION -> Diagonally Split System -> Failure Warning Switch -> Fluid Level Sensor -> Front & Rear Split System -> Metering Valve -> Proportioning Or Pressure Control Valve -> SYSTEM OPERATION -> Testing Warning Lamp Operation
Vehicle: 1994 Buick Regal Custom 3.8 V6 GAS

SYSTEM OPERATION
Front & Rear Split System

When the brake pedal is depressed, both the primary (front brake) and the secondary (rear brake) master cylinder pistons are moved simultaneously to exert hydraulic fluid pressure on their respective systems, Fig. .

If the rear (secondary) brake system fails, initial brake pedal movement will cause the unrestricted secondary piston to bottom in the master cylinder bore. Primary piston movement will displace hydraulic fluid in the primary section of the master cylinder to actuate the front brake system.

If the front (primary) brake system fails,...

Vehicle: 1994 Buick Regal Custom 3.1 V6 GAS

AC-DELCO TANDEM DIAPHRAGM TYPE

This unit utilizes a vacuum power chamber, consisting of a front and rear shell, housing divider, front and rear diaphragm, plate assemblies, hydraulic pushrod and a diaphragm return spring, Figs. and .

The unit operates in much the same manner as the single diaphragm unit described previously. The diaphragm and plate assemblies utilize the pressure differential between the engine intake manifold vacuum and atmospheric pressure to assist in braking.

Includes anti-lock brakes, disc, drum, power and hydraulic brake services diagnostics and procedures for domestic and imported 1994 Buick Regal cars and light trucks from 1990+.

Power Brake Units -> General Service
Vehicle: 1994 Buick Regal Custom 3.1 V6 GAS

Two basic types of power assist mechanisms are used: vacuum assist diaphragm assemblies, which use engine vacuum or, in some cases vacuum pressure developed by an external vacuum pump. The second type is a hydraulic pressure assist mechanism, which use pressure developed by an external pump (usually the power steering pump). Both systems act to increase the force exerted on the master cylinder piston by the operator. This in turn increases the hydraulic pressure delivered to the wheel cylinders, while decreasing driver effort necessary to obtain acceptable stopping performance.

MANUAL BLEEDING

Pressure bleeding is recommended for all hydraulic systems. However, if a pressure bleeder is unavailable, use the following procedure. Brake fluid damages painted surfaces. Immediately clean any spilled fluid.

  • Remove vacuum reserve by pumping brakes several times with engine off.
  • Fill master cylinder reservoir with clean brake fluid. Check fluid level often during bleeding procedure; do not let reservoir fall below half full.
  • If necessary, bleed master cylinder as follows:
    • Disconnect master cylinder forward brake line connection until fluid flows from reservoir. R...
