Q: How to Maintain and Fix the Brake Booster on a Lincoln LS?
A: Before repairing or servicing the vacuum brake booster start by first removing the wiper arm nuts then all wiper arms and lastly disconnecting the washer hose while taking out the cowl cover through pushpins and rubber trim removal. The next step requires removal of the vacuum hose bracket nut before placing the bracket aside and completing the task by taking out the cowl brace center and end bolts. First remove the brake master cylinder then disconnect the power brake booster check valve as well as its electrical connector when present. The coolant reservoir needs to be removed by loosening its bolts while disconnecting the attached hose. Begin by taking off the brake pedal pin clip along with its pin before you loosen the power brake booster nuts and eliminate the component itself. First install the new power brake booster before fastening it with the booster nuts. Install the brake pedal pin followed by its clip then proceed to bolt the radiator coolant recovery reservoir into position and attach its hose. The installation process includes attaching the power brake booster electrical connector when present followed by joining the check valve and the coolant reservoir return hose. After placing the brake master cylinder it is necessary to bolt down the cowl brace end and center then secure the vacuum hose bracket nut. To complete the task install the wiper arm nuts and washer hose, bleed the brake system and reinstall cowl cover along with rubber trim and pushpins.
Q: How to service and repair the vacuum brake booster on Lincoln Navigator?
A: Start vacuum brake booster service and repair operations by taking out the air cleaner element. The next step requires users to remove and set aside the degas bottle/lower air cleaner housing assembly by disconnecting its two securing bolts and tightening them to 15 Nm (11 lb-ft) torque. Operate the brake pedal at least five times with the engine turned off in order to drain vacuum from the brake booster. Disconnect the brake fluid level switch and support the master cylinder with mechanic's wire before removing the two brake master cylinder nuts and set off the master cylinder aside when reinstalling the nuts to 25 Nm (18 lb-ft) torque. Vehicles equipped with roll stability control need technicians to disconnect the solenoid electrical connector of the brake pedal travel. The brake booster requires its connection points to be separated between the brake pedal travel sensor and the manifold vacuum outlet assembly. The brake pedal must be positioned at its resting point before you can detached the stoplamp switch and speed control deactivator switch by disconnecting their electrical connectors while turning the stoplamp switch clockwise. Pluck out the brake pedal arm pin to simultaneously sever the booster push rod that links the brake pedal arm. The four brake booster-to-pedal bracket nuts require removal through opening the sound insulation to evacuate the brake booster from its position. After installation refit these nuts to 27 Nm (20 lb-ft). Before installing the stoplamp switch you must position the brake pedal at-rest while connecting the booster push rod to prevent incorrect adjustment which could lead to damaging the system. Vehicles with roll stability control need a scan tool calibration and the full removal and installation procedure should be done in reverse.
Q: How to service and repair the vacuum brake booster on Lincoln Town Car?
A: Service and repair operations on the vacuum brake booster start with disconnecting the battery ground cable along with the fluid level sensor connector. Starting with bracket position of the speed control cable and next detach the power brake booster check valve. Begin services of the vacuum brake booster by unscrewing the brake master cylinder nuts before removing the wiring harness bracket followed by placing all components to the side. Take out the brake master cylinder after disconnecting it before setting it aside. The instrument close-out panel removal starts with pushpin removal and further requires the stoplight switch retaining pin to be taken out. Unfasten the brake pedal pin from the stoplight switch and booster push rod before removing the power brake booster retaining nuts to pull out the system. Edge the brake switch installation by placing the closed hole facing away from the brake pedal arm while positioning the open hole upward before proceeding with the removal process in reverse order.
