How to Replace Emergency Brakes in a Lincoln Navigatorby Contributor
The emergency brakes on your vehicle were originally used to stop it when the regular brakes failed. However, the brakes on a Lincoln Navigator now rarely fail, and the emergency brakes are more often used to keep the vehicle from moving while parked. The most common source of failure for emergency brakes occurs when they aren't used for a period of time, causing the brake cable to rust and seize.
Determine which type of emergency brakes your Lincoln Navigator will need. Emergency brakes typically function by activating the regular braking system on the driving wheels. The emergency brakes for the Lincoln Navigator use disc brakes on the rear wheels.
Release the parking brake and pull down on the front parking brake cable at the coupler to relieve the tension on the brakes. Insert a 4mm pin into the parking brake lever and remove the brake disc with a socket wrench.
Remove the front parking brake shoe retaining clip and pin. Remove the parking brake shoe adjuster by spreading the bottom of the parking brake shoes apart with a brake adjuster tool. Remove the parking brake shoe adjuster spring and slide the forward parking brake shoe up and out of the guide flange.
Detach the parking brake shoe return spring, retaining clip and pin so you can remove the rearward parking brake shoe.
Lubricate the contact points on the new parking brake shoe with silicone brake caliper grease.
Install the new parking brake shoes by reversing the removal procedure. Use brake adjusting gauge 206-D002 to adjust the parking brake shoe diameter to 0.02 inch less than the inside diameter of the drum portion of the rear brake disc.
