ABSTRACT:
A control for a spring-apply, pressure release brake system having a pilot signal-generating valve and a slave brake valve interconnected by a pilot signal line. Hydraulic pressure is directed to both the pilot valve and the slave valve. Manual stroking of the pilot valve modulates the pressure to the signal line. A spool within the slave valve senses both the signal pressure and the brake pressure and moves to an equilibrium position to equalize the signal and brake pressures.
