Proportioning Valve

Early Production ABS Operation

Hydraulic Assembly:

In place of the conventional differential pressure/proportioning valve, the Anti-lock Brake System (ABS) utilizes screw-in proportioning valves. Each rear brake circuit has its own screw-in proportioning valve which is attached to the rear brake outlet ports of the hydraulic assembly. These valves limit pressure to the rear brakes after a threshold pressure has been reached, thus improving front to rear brake balance during normal braking. The Proportioning Valves are serviced separately.
