NOTE: Before proceeding with this procedure, review applicable Service Precautions.

REMOVAL

CAUTION: The vacuum in the power brake booster must be pumped down before removing the master cylinder to prevent the booster from sucking in any contamination. This can be done by pumping the brake pedal while the engine is not running until a firm brake pedal is achieved.

1. With the engine not running, pump the brake pedal 4-5 strokes until the pedal feel is firm.
2. Disconnect the negative (ground) cable from the battery and isolate the cable.
3. Disconnect the positive cable from the battery, then remove the battery from the battery tray. There is one nut securing the clamp on the backside of the battery holding it in place.






4. Disconnect the wiring harness connector from the brake fluid level switch on the master cylinder reservoir.
5. Disconnect the primary and secondary brake tubes from master cylinder. Install plugs in the master cylinder outlet ports.
6. Clean the area around where the master cylinder attaches to the power brake booster using a suitable brake cleaner such as Mopar Brake Parts Cleaner or an equivalent.
