BRAKE SERVICE PROCEDURES FOR 1993 Pontiac Bonneville AUTOMOBILES

Includes anti-lock brakes, disc, drum, power and hydraulic brake services diagnostics and procedures for domestic and imported 1993 Pontiac Bonneville cars and light trucks from 1990+.

Anti-lock Brakes -> Bonneville, Eighty Eight, LeSabre, Ninety Eight, Park Avenue, 1992 DeVille & Fleetwood (FWD) (Teves Type) -> Description -> BRAKE WARNING LAMP -> ELECTRONIC BRAKE CONTROL MODULE (EBCM) -> WHEEL SPEED SENSORS
Vehicle: 1993 Pontiac Bonneville SE 3.8 V6 GAS

Refer to Fig. , for overview of anti-lock brake system.

The purpose of the anti-lock brake system is to prevent wheel lock-up under heavy braking conditions, on virtually any road surface. When a wheel locking condition exists, the pressure modulator valve (PMV) assembly isolates each wheel hydraulic circuit, then begins modulation of fluid pressure to each wheel according to wheel speed input to the EBCM. The PMV is controlled by the Electronic Brake Control Module (EBCM).

Modulation occurs by means of three ABS modes: pressure hold, pressure reduce and pressure increase. The PMV ass...

Vehicle: 1993 Pontiac Bonneville Ssei 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,...
