Proportioning Valve

Valve operates by restricting, at a given ratio, hydraulic pressure to rear brakes when system hydraulic pressure reaches a certain point. This improves front-to-rear brake balance at high deceleration, when a percentage of rear weight is transferred to front wheels. Valve reduces rear brake pressure, and delays rear wheel skid. On light pedal application valve allows full hydraulic pressure to rear brakes.
