A brake pedal that sinks slowly to the floor under steady pressure, rather than holding firm, often points to internal foot valve wear rather than a leak elsewhere, calling for the Bendix Foot Valve. Internal seals separate the metered chamber from atmosphere, and worn seals let air bleed off internally while the pedal is held steady. Replacing a valve that bleeds down internally restores a pedal that holds its position instead of creeping toward the floor. Rebuilt to new tolerances, the Bendix 800633 keeps pedal position and applied pressure matched the way the system was originally calibrated.
