Abstract
A two stage brake pressure proportioner using brake fluid flow energy to accelerate actuating movement of a control valve once inertia has begun to move the control valve, achieving a precise deceleration trip point under all braking conditions. The proportioning pistons are preset for proportioning operation during the initial phase of brake actuation before inertial actuation.
