Section 16 (Anti-Lock Brake System): Description

WARNING: This page is about a different car, the 1992 Buick Park Avenue and 1992 Buick LeSabre. However, it is still accessible from the selected car via links, so may be relevant.

The Teves 4-wheel Anti-Lock Brake System (ABS) and Traction Control System (TCS) are designed to prevent wheel lock-up during heavy braking and acceleration slip at speeds less than 25 MPH. The ABS allows driver to maintain steering control while stopping vehicle in shortest distance possible, while TCS allows fast acceleration. Major components include the following: pump motor, Pressure Modulator Valve (PMV) assembly, fluid reservoir with integral filter, wheel speed sensors (4), fluid level sensor, Electronic Brake Control Module/Electronic Brake Traction Control Module (EBCM/EBTCM), brake booster/master cylinder assembly and BRAKE and ANTI-LOCK warning lights. See Fig 1 .

Covered vehicles may be equipped with TCS. TCS uses ABS components to control wheel spin by applying brakes to slipping wheel.
