Brake Proportioning/Combination Valve: Description and Operation
Proportioning Valve
The proportioning valve prevents the rear wheels from locking and resultant skidding that would occur during hard braking due to transfer of vehicle
weight toward the front wheels. The valve distributes a reduced pressure to the rear wheel brakes as compared with the pressure to the front wheel brakes
when a specified master cylinder fluid pressure (called "split point") is exceeded as shown in the diagrams below.
