    Hydraulic Brake Systems -> Description -> Hydraulic Control Valves -> Master Cylinder
    Vehicle: 2001 GMC Sierra 3500 8.1 V8 GAS

    Master Cylinder

    Some vehicles use a conventional tandem master cylinder with two hydraulic pistons operating in-line. The primary piston controls the front brake system and the secondary piston controls the rear brake system.

    Other models use a master cylinder that operates the same as the conventional master cylinder, but also incorporates a quick take-up feature in the rear chamber to reduce excessive pedal travel which may result from increased fluid displacement required to move the low drag caliper piston out against the rotor.

    The quick take-up uses a spring-loaded ball check val...

    Do not smoke or allow an open flame of any type when working on or near any fuel system related components. The highly flammable vapor mixtures may ignite, resulting in serious personal injury.

    Prior to disconnecting fuel lines, the fuel system pressure must be relieved to prevent accidental spray of fuel.

    After the battery has been disconnected and reconnected, some abnormal driveability symptoms may occur. The vehicle may need to be driven while the vehicle relearns its adaptive strategy.
