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

The service and repair process for the vacuum brake booster begins with removing the air cleaner element along with degas bottle/lower air cleaner housing assembly bolts before storing them aside while tightening bolts to 15 Nm (133 lb-in) for reinstallation. The brake booster vacuum should be released through five pedal pressing cycles before engine shutdown. You should disconnect the brake fluid level switch after installing mechanic's wire to support the master cylinder, but only remove the two brake master cylinder nuts before placing the master cylinder aside while tightening these nuts to 25 Nm (18 lb-ft). Remove the electrical connector which controls the brake pedal travel solenoid on all vehicles that come with Roll Stability Control (RSC(R)). Proceed with disconnecting the following elements: brake pedal travel sensor electrical connector as well as the manifold vacuum outlet assembly from the brake booster. When removing the stoplamp switch, it must be accomplished with the brake pedal in resting position so the switch plunger stays compressed because damage to hardware will result. Meticulously remove the stoplamp switch before proceeding to separate the brake pedal arm pin and disconnecting the booster push rod from the brake pedal arm. Users can remove the four brake booster-to-pedal bracket nuts by accessing the hidden locations after folding back the sound insulation then should remove the brake booster while using 27 Nm (20 lb-ft) torque when reinstalling the nuts. The correct installation of the stoplamp switch requires positioning of the brake pedal at rest since an incorrect placement could damage the hardware. Vehicles equipped with Roll Stability Control (RSC(R)) require customers to use a scan tool for ABS module calibration according to its instructions.

Lincoln Navigator cars contain the Brake Booster which is of significant influence as it lessens the force that a driver employs while pressing the brake. It enlarges the hydraulic pressure from the master cylinder by employing a vacuum chamber, and this intensifies the force that a driver applies on the brake pedal. There are two main types of boosters used in Navigator vehicles: includes vacuum-operated boosters and hydraulic boosters. Vacuum boosters work on the difference of vacuum pressure existing inside the engine and atmospheric pressure while hydraulic boosters work on fluid pressure to help in the application of brake. These booster are rather dependable but may wear out from time to time and would have to be replaced. Lincoln Navigator boasts of different performance brake boosters and power brake conversion kits to maximize simple as well as effective braking for any car.
