BRAKE SERVICE PROCEDURES FOR 1990 Lincoln Mark VII AUTOMOBILES
DISC BRAKES, FORD MOTOR CO. -> General Information -> PROPORTIONING VALVE -> DESCRIPTION -> TESTING
Vehicle: 1990 Lincoln Mark VII LSC 5.0 V8 GAS
DESCRIPTION
The proportioning valve (when used),Fig. , provides balanced braking action between front and rear brakes under a wide range of braking conditions. The valve regulates the hydraulic pressure applied to the rear wheel cylinders, thus limiting rear braking action when high pressures are required at the front brakes. In this manner, premature rear wheel skid is prevented.
TESTING
When a premature rear wheel slide is obtained on a brake application, it usually is an indication that the fluid pressure to the rear wheels is above the 50% reduction ratio for the rear line ...
