How to service and repair the vacuum brake booster on Lincoln MKX?

Servicing the vacuum brake booster begins with removing the stoplamp switch when the brake pedal rests at its position. Maintain compression on the plunger before rotating the bracket. Removing the switch while its plunger is extended will damage the device. The brake booster check valve needs disconnecting from the brake booster before master cylinder seal removal from the booster. The vacuum hose assembly should be directed properly to bypass surrounding components before vacuum hose and wire harness disconnection from their studs to place them aside. The brake booster push rod pin and clip must be removed before detaching the push rod from the brake pedal along with removing the four brake booster nuts which should be tightened to 23 Nm (17 lb-ft) during installation. Put the stoplamp switch together with the attached booster push rod when the brake pedal sits in the at-rest position to ensure proper adjustment and protection of the switch during the installation which follows the removal process in reverse.

The Brake Booster in Lincoln MKX automobiles is meant to improve dash braking by lessening the force required from the driver in applying the brake pedal. A vacuum mechanism functions as the major subcomponent in this aspect; it increases the force applied on the brake pedal to act on the master cylinder making the braking mechanism smoother and more forceful. Lincoln MKX cars may incorporate varying types of Brake Boosters; Vacuum operated boosters and hydraulic boosters are some. In vacuum boosters, a vacuum is developed and boosted up in the chamber from the engine vacuum side and regulated with the help of atmospheric pressure while in hydraulic boosters, hydraulic pressure of the power steering pump or an electric pump is used. The variation between these types can influence the general braking, increase it - vacuum boosters are more trustworthy, yet with certain drawbacks in the moment when the engine is not running.
