HYDRAULIC BRAKES, FORD MOTOR CO. -> BLEEDING BRAKES -> DUAL MASTER CYLINDER BLEEDING NOTES -> SYSTEM PRIMING -> TESTING DUAL MASTER CYLINDERS -> WHEEL BLEEDING SEQUENCE
Vehicle: 1990 Mercury Cougar LS 3.8 V6 GAS
Pressure bleeding is recommended for all hydraulic brake systems.
The bleeding operation itself is fairly well standardized. First step in all cases is cleaning the dirt from the filler cap before removing it from the master cylinder. This should be done thoroughly.
Pressure bleeding is fastest because the master cylinder doesn't have to be refilled several times, and the job can be done by one man. To prevent air from the pressure tank getting into the lines, do not shake the tank while air is being added to the tank or after it has been pressurized. Set the tank in the required ...

Vehicle: 1990 Mercury Cougar XR-7 3.8 V6 GAS
HYDRAULIC ACTUATION UNIT
The hydraulic actuation unit,Figs. and , consists of two sections, the master cylinder and brake booster, which are arranged in the conventional fore and aft sequence. The booster contains a control valve, located in a parallel bore above the master cylinder.
ELECTRIC PUMP ASSEMBLY
This system uses high pressure brake fluid stored in a hydraulic accumulator,Fig. , for power assist as well as for rear wheel braking. The accumulator is a gas filled pressure chamber that stores brake fluid up to 2600 psi. The fluid is pressurized by an electric motor driven...

DISC BRAKES, FORD MOTOR CO. -> General Information -> PROPORTIONING VALVE -> DESCRIPTION -> TESTING
Vehicle: 1990 Mercury Cougar LS 3.8 V6 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 ...
