Power Brake Units -> Bendix Brake Booster -> Description
Vehicle: 1998 Chevrolet Blazer 4.3 V6 GAS
In order to properly service power brake systems, a thorough understanding of the power assist system is necessary.

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, ensure 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 convention...
