To start removing the vacuum brake booster, fully pump down the reserve vacuum by repeatedly pressing down the brake pedal 4-5 times when the engine is not running until the pedal becomes firm. Remove both cable connectors from your battery and pull out the battery and its support clamp and nut. Unscrew the engine filler tube from the battery tray and then disconnect the hose leading to the vacuum tank in cars with speed control. After that, remove two nuts and one bolt holding the battery tray to take the tray out. If your car has a speed control servo, disconnect it, unscrew the two nuts holding the servo onto the mount and put the servo away. Take the wiper module out and remove the wiring from the brake fluid level switch in the reservoir of the master cylinder. Use Mopar(R) Brake Parts Cleaner to clean the mounting area of the master cylinder onto the power brake booster. Remove the primary and secondary brake tubes from the ABS integrated control unit or non-ABS junction block and put sealing plugs in the open ports of these brake tubes. Pull the two nuts off that hold the master cylinder to the power brake booster and pull the master cylinder straight out, remembering to put on a new vacuum seal. Take the hose off the check valve, but keep the check valve where it is. Within the vehicle, remove the panel under the instrument panel, reach the booster input rod to brake pedal connection and use a small screwdriver to take off the clip attached to the brake pedal pin, throwing it out and placing a new clip during reassembly. First, pull the booster input rod off the pedal pin, undo the four nuts attaching the booster to the dash panel and slide the booster out in front of the engine. You should never try to open the power brake vacuum booster, as it can only be serviced as one whole device.
