BRAKE SERVICE PROCEDURES FOR 1993 Mercury Grand Marquis AUTOMOBILES
Power Brake Units -> Description -> BENDIX DIAPHRAGM TYPES -> Operation -> VACUUM ASSIST DIAPHRAGM TYPE
Vehicle: 1993 Mercury Grand Marquis 4.6 V8 GAS
On vehicles equipped with anti-lock brakes refer to appropriate "Anti-Lock Brakes".
VACUUM ASSIST DIAPHRAGM TYPE
The vacuum assist diaphragm assembly multiplies the force exerted on the master cylinder piston in order to increase the hydraulic pressure delivered to the wheel cylinders while decreasing the effort necessary to obtain acceptable stopping performance.
Vacuum assist units get their energy by opposing engine vacuum to atmospheric pressure. A piston, cylinder and flexible diaphragm utilize this energy to provide brake assistance. The diaphragm is balanced with engine vacuum unt...
