Escort ZX2 L4-2.0L DOHC VIN 3 (2000)
Brake Proportioning/Combination Valve: Description and Operation
With ABS
Without ABS
The brake system has a brake pressure control valve that regulates hydraulic pressure in the rear brake circuit. On non ABS systems, the brake
pressure control valve is located on the brake master cylinder. On ABS systems, the brake pressure control valve is located on the bulkhead. When the
brake pedal is applied, full rear circuit pressure passes through the brake pressure control valve until the split point of the brake pressure control valve
is reached. Above the split point, the brake pressure control valve begins to reduce hydraulic pressure to the rear brake circuit. This creates a balanced
braking condition between the front and rear wheels while maintaining balanced hydraulic pressure at each wheel.
