• Q: How to Maintain and Fix a Brake Booster on 2008 Chrysler Pacifica?

  A: Before working on your vacuum brake booster, push the driver's seat all the way back and remove the negative cable from the battery post. It is necessary to empty all the air in the power brake booster so that the master cylinder is not corrupted when it is removed; accomplish this by pumping the brake pedal with the engine turned off until a firm feel is detected in the pedal, usually after performing 4-5 strokes. You should then take the coolant recovery bottle out of its mount and get the master cylinder off. Disconnect the hose to the check valve by itself without getting rid of the valve. Remove the booster push rod rods from the brake pedal by separating the screwdriver between the center tang in the brake pedal pin retaining clip, rotating it with a small screwdriver which will let the clip slide over the pin and discard the old clip-be sure to replace it with a new one when reassembling. Unscrew the stop lamp switch from the vehicle, then add in a new stop lamp switch when it is installed. Finally, remove the four power brake booster mounting nuts and slide the unit forward to get it through the engine compartment.
