BRAKE SERVICE PROCEDURES FOR 1993 Buick Lesabre AUTOMOBILES

Includes anti-lock brakes, disc, drum, power and hydraulic brake services diagnostics and procedures for domestic and imported 1993 Buick Lesabre 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 Buick Lesabre Custom 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...

Power Brake Units -> General Service
Vehicle: 1993 Buick Lesabre Limited 3.8 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.
