Brake Proportioning/Combination Valve: Description and Operation
Proportioning Valve
Fig. 33 Proportioning Valve
Fig. 34 Proportioning Valve With ABS
This valve assembly on non-ABS models is of a dual proportioning valve design.
The proportioning valve on non-ABS models transfers full braking force to the rear brakes until a preset ratio called the split point is achieved. At this
point the pressure increase is routed away from the rear brake system to prevent rear wheel lock-up.
On models with ABS, two screw in proportioning valves are used. These proportioning valves are attached to the rear brake outlets of the hydraulic
control unit (HCU).
The brake warning light will come on when the parking brake is applied with the ignition turned On. The same light will also come on when one of the
two service brake systems fail.
