Anti-lock Brakes -> ABS-VI Anti-Lock Brake System -> Description -> System Operation
Vehicle: 1992 GMC C1500 Suburban 5.7 V8 GAS
System Operation
This braking system, Fig. , is designed to reduce the occurrence of wheel lock-up during severe braking conditions. To accomplish this function, the system regulates hydraulic brake line pressure when a microprocessor, located inside the Electronic Brake Control Module (EBCM), determines one or more of the wheels is about to lose traction during braking. The EBCM will allow the hydraulic modulator to change brake pressures several times each second to provide maximum vehicle control. This system cannot increase brake pressure above the master cylinder pressure appl...

Vehicle: 1992 GMC C1500 Suburban 5.7 V8 GAS
The braking system can be bled manually or with pressure bleeding equipment. If bleeding manually, check fluid level frequently.
Brake fluid should never be reused. Before driving the vehicle, check brake operation to ensure a firm pedal has been obtained.
Brake fluid will damage electrical connections and painted surfaces. Use shop cloths, suitable containers, and fender covers to prevent brake fluid from contacting these areas. Always seal and wipe off brake fluid containers to prevent spills.
