Thunderbird V8-4.6L VIN W (1997)
Brake Proportioning/Combination Valve: Description and Operation
DESCRIPTION
The brake pressure control valve regulates hydraulic pressure in the rear brake system. They are remote-mounted brake pressure control valves.
OPERATION
The brake pressure control valve operates as follows:
^
When brake pedal is applied, the full rear brake fluid pressure passes through the proportioning valve to the rear brake system until the valve's
split point is reached.
^
Above its split point, the proportioning valve begins to reduce the hydraulic pressure to the rear brakes.
^
The reduced pressure creates a balanced braking condition between the front and rear wheels to minimize rear wheel skidding during hard
braking.
