Removal

PROCEDURE

CAUTION: On ABS equipped vehicles, vacuum in power booster must be pumped down before removing master cylinder to prevent booster from sucking in any contamination. This can be done simply by pumping the brake pedal until a firm pedal is achieved, with the ignition off.

1. On ABS equipped vehicles, be sure engine is not running, and pump the brake pedal until a firm pedal is achieved (4-5 strokes).

Master Cylinder Fluid Level Sensor:

2. Remove vehicle wiring harness connector, from brake fluid level sensor, in master cylinder brake fluid reservoir.

Primary And Secondary Brake Tubes Without ABS Brakes:

3. Disconnect the primary and secondary brake tubes from the master cylinder. Install plugs at all open brake tube outlets on master cylinder assembly.
4. On vehicles equipped with ABS, clean area where master cylinder attaches to booster using a suitable brake cleaner product such as Mopar Brake Parts Cleaner or an equivalent.

Master Cylinder Mounting To Vacuum Booster:

5. Remove the 2 nuts attaching master cylinder housing to power brake vacuum booster.
6. Slide master cylinder assembly straight out of the power brake vacuum booster.

CAUTION: On vehicles equipped with ABS, the master cylinder is used to create the seal for holding vacuum in the power brake vacuum booster. The vacuum seal in the front of the power brake vacuum booster MUST be replaced whenever the master cylinder is removed from the power brake vacuum booster.

Removing Seal From Vacuum Booster:

7. If vehicle is equipped with ABS, remove vacuum seal located in the front of the power brake vacuum booster. Vacuum seal is removed by carefully inserting a small screw driver between the push rod of the power brake vacuum booster and vacuum seal and pry seal out of power brake vacuum booster. Do not attempt to pry seal out of master cylinder by inserting a tool between seal and power brake vacuum booster.
