BRAKE SERVICE PROCEDURES FOR 1993 GMC Sonoma AUTOMOBILES
Includes anti-lock brakes, disc, drum, power and hydraulic brake services diagnostics and procedures for domestic and imported 1993 GMC Sonoma cars and light trucks from 1990+.
Power Brake Units -> Bendix Brake Boosters -> General Service
Vehicle: 1993 GMC Sonoma 2.5 L4 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...

If the caliper is cracked or fluid leakage through the casting is evident, it must be replaced as a unit.
Brake Roughness
The most common cause of brake chatter on disc brakes is a variation in thickness of the disc. If roughness or vibration is encountered during highway operation or if pedal pumping is experienced at low speeds, the disc may have excessive thickne...
