Removal (Without ABS)

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

With the engine not running, pump the brake pedal 4-5 strokes until the pedal feel is firm.
Disconnect the negative (ground) cable from the battery and isolate the cable.
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.
Remove the vehicle wiring harness connector from brake fluid level switch in master cylinder brake fluid reservoir.
Disconnect the 2 brake tubes from the master cylinder, and 2 brake tubes from the proportioning valves. Install plugs at all of the open brake tube outlets on the master cylinder.
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.
Remove the 2 nuts attaching the master cylinder to the power brake booster.
Slide the master cylinder straight out of the power brake booster.
To remove the proportioning valves, unthread each from the master cylinder.
