Brake Proportioning/Combination Valve: Description and Operation
Brake Pressure Control Valve
The brake pressure control valve proportions the pressure to the rear brakes.
^
When the brake pedal is applied, brake fluid pressure passes through the brake pressure control valve to the rear brake system until the valve split
point is reached.
^
Above its split point, the brake pressure control valve begins to reduce the hydraulic pressure to the rear brakes, creating a balanced braking
condition between the front and rear brakes.
