  Q: How to service and repair the vacuum brake booster on Lincoln LS?

  A:

  The vacuum brake booster servicing process starts with taking off the Wiper Arm nuts followed by the wiper arms. Next, disconnect the washer hose and remove the cowl cover by pulling out pushpins along with rubber trim. First remove the vacuum hose bracket nut before setting the bracket aside then carry out the same procedure to remove the cowl brace center and end bolts and the bracket. The first step must include disconnecting the Coolant Reservoir return hose and taking out the Brake Master Cylinder before removing the power brake booster check valve and cutting off any necessary electrical connector. Begin by taking out the coolant reservoir bolts then disconnect the radiator to engine vent after which you should remove the coolant reservoir. Detach first the brake pedal pin and clip then use the booster nuts to remove the power brake booster unit. After placing the power brake booster correctly you should install the booster nuts before reinserting the brake pedal pin along with its clip. The installation requires reinstalling radiator coolant recovery reservoir bolts while you connect the coolant reservoir hose along with power brake booster electrical connector (if applicable) before attaching the check valve and coolant reservoir return hose. All installation steps on the brake master cylinder and cowl brace end and center bolts must include vacuum hose bracket nut as well as the cowl cover and its rubber trim with pushpins. Finish the procedure by attaching the washer hose followed by wiper arm nut installation then perform brake system bleeding followed by observing and maintaining coolant levels when needed.
