BRAKE SERVICE PROCEDURES FOR 1994 Chevrolet Astro AUTOMOBILES
Includes anti-lock brakes, disc, drum, power and hydraulic brake services diagnostics and procedures for domestic and imported 1994 Chevrolet Astro cars and light trucks from 1990+.
Power Brake Units -> Bendix Brake Boosters -> General Service
Vehicle: 1994 Chevrolet Astro 4.3 V6 GAS
Certain general service procedures apply, regardless of whether the brakes are vacuum or hydraulically assisted. Only top quality, clean brake fluid should be used. More seals and valves are used with power brake systems than with ordinary brakes, so an inferior brake fluid will do much more damage. For the same reason, be sure all dirt is kept out of the system. Additionally, care must be taken not to mix the fluids of the booster hydraulic system and brake hydraulic system as the fluids are not compatible.
If the power unit fails, the brakes will still operate, as the conventio...

Anti-lock Brakes -> ABS-VI Anti-Lock Brake System -> Description -> System Operation
Vehicle: 1994 Chevrolet Astro 4.3 V6 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...
