How do you change a brake booster on a 2003 Chrysler concord?

Answer 1

First you start by removing the wiper arms from the rotation shafts. Next remove the black plastic wiper drive system covers. These are screwed down with torx sheet metal screws. Then remove the strut tower brace which is held down with 14mm hex cap screws. Carefully remove the wiper washer hose which is clipped to the under side of the strut tower brace prior to completely removing the brace. There are two 13 mm nuts which hold the brake master cylinder to the booster that must be removed and you will need a 10" long 3/8 extension with either a wobble end or a universal. Use care not to drop the nuts as access is tight. Remove the two wire electrical connector from the master cylinder. There are several harnesses and vacuum hoses attached to a bracket that is held to the master cylinder under the two 13mm nuts. Take the vacuum supply hose off the master and then carefully place the bracket with the harness and attached vacuum hoses and push towards the engine to create room to remove the master and booster. The master comes off next. You may need to use some PB blast and tap on it or pry on it as they normally are corroded onto the booster. Once free, place the master as far forward as you can with out kinking or damaging the two brake lines. The next phase is under the dash and if you weigh more than 185 pounds it might be easier to remove the front seat. You are going to need a good light to work under the dash. Once you are situated and using a flat tip screw driver you must remove the brake push rod retainer clip. Take care not to damage it and if in doubt you should replace it. Pull the brake booster push rod away from the brake pedal. After this step remove 4 10mm hex nuts from the booster. A 1/4" air ratchet is best for this to speed things up. Once the nuts are off go back under hood and remove the booster. This is easier said than done as it is a very tight fit. Prior to installation of the new or re-manufactured booster make sure the master cylinder push rod length is equal to the one you removed. To install reverse the procedure and be sure to insure all fasteners are adequately tightened. Total time to do this job depends on experience and skill but should range between two to three hours. Good luck.
