  Q: How to Maintain and Fix the Parking Brake Shoes on a Mercury Grand Marquis?

  A:

  Service and repair of parking brake shoes require turning off the Air Suspension switch found in the luggage compartment to stop air springs from unexpected inflation or deflation during the process. Start the project by taking out the brake disc from the rear wheel. You can take out the adjuster by disconnecting both the brake shoe return spring and the adjusting spring through the help of a scratch awl. You should detach the parking brake actuator by pushing the brake shoes to connect before pulling out the actuator and freeing the Parking Brake Cable end. My next step involves the removal of brake shoe hold-down springs followed by the parking brake shoe and its attached linings. Check every component for signs of destructive wear but replace all damaged parts. To reassemble start by applying anti-seize lubrication to the brake shoe contacts and follow the uninstillation procedure in reverse order. The threads of the adjusting screw need lubrication with anti-seize lubricant. The proper brake adjusting gauge enables users to set rear brake shoe and lining diameters at a width of 0.5 mm (0.020 inch) less than the drum portion of the brake disc while adjusting parking brake cable tension and then verifying parking brake functionality.

  Q: How to service and repair the parking brake shoes on Mercury Grand Marquis?

  A:

  The service and repair of parking brake shoes should begin with turning off Air Suspension electrical power by using the air suspension switch in the luggage area to avoid unexpected changes in air spring volume when hoisting or jacking or towing the vehicle. Before proceeding start by hoisting and supporting the vehicle before taking out the tire and wheel assembly in addition to the brake disc. Carefully remove the brake shoe adjusting screw springs through the use of a scratch awl because it makes the removal and installation process easier. The procedure starts by removing the brake shoe adjustment screw together with the brake shoe hold down springs before extracting both the parking brake shoe and linings. All components need inspection for wear signs and damage before doing any required replacements. Installation requires the opposite steps used for removal while using High Temperature Nickel Anti-Seize Lubricant F6AZ-9L494-AA or equivalent ESE-M12A4-A Ford specification to grease the brake shoe contact points before putting on rear brake shoes. You must also lubricate the adjusting screw threads by using the same lubricating substance. You should adjust the rear brake shoe with a gauge so that its diameter with lining equals 0.5 mm (0.020 inch) less than the drum portion of the brake disc.
