Any time the brake drums are removed for brake service, the braking surface diameter should be checked with a suitable brake drum micrometer at several points to determine if they are within the safe oversize limit stamped on the brake drum outer surface. If the braking surface diameter exceeds specifications, the drum must be replaced. If the braking surface diameter is within specifications, drums should be cleaned and inspected for cracks, scores, deep grooves, taper, out of round and heat spotting. If drums are cracked or heat spotted, they must be replaced. Mi...

HYDRAULIC BRAKES, FORD MOTOR CO. -> BLEEDING BRAKES -> DUAL MASTER CYLINDER BLEEDING NOTES -> SYSTEM PRIMING -> TESTING DUAL MASTER CYLINDERS -> WHEEL BLEEDING SEQUENCE
Vehicle: 1991 Mercury Sable 3.0 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 ...

ANTI-LOCK BRAKES, FORD MOTOR CO. -> Sable/Taurus & Town Car, 1990-91 Continental -> OPERATION
Vehicle: 1991 Mercury Sable 3.0 V6 GAS
When brakes are applied, fluid is forced from the master cylinder outlet ports to the hydraulic control unit (HCU) inlet ports. This pressure is transmitted through four normally open solenoid valves contained inside the HCU, then through outlet ports of the HCU to each wheel. The primary (rear) circuit of the master cylinder feeds the right front and left rear brakes. The secondary (front) circuit feeds the left front and right rear brakes.
When the electronic control unit ECU senses wheel lock conditions, based on wheel speed sensor data, it pulses the normally open solenoid valve cl...
