Q: What Precautions Should Be Taken Before Beginning the Brake Disc Service and Repair on Lincoln Town Car?
A: The brake rotor/disc service demands turning off the air suspension system electrical power so air springs operate safely. Electrical cutoff will prevent uncontrolled air spring expansion or contraction leading to vehicle body movement that creates personal injury risks. Brake pads need initial removal for the process. The parking brake shoes should be retracted through the adjustment hole by inserting an adjusting tool into the far end of the access plug slot and turning it toward the backing plate after removing this plug to free a bound brake disc. Check the brake disc for freedom afterward and proceed to machine it with a hub-mount brake lathe; measure the disc and recondition it or replace it based on its specifications. The brake disc along with wheel and wheel hub should be cleaned with brake parts cleaner then treated with anti-seize lubricant at both hub flange and pilot areas. The installation process ends with reverse motion of removal steps while setting the air suspension service switch to its ON position.
Q: How to service the rear brake disc on Lincoln Navigator?
A: Start the process of servicing the rear brake disc by switching off the air suspension power in the right-hand kick panel area because this prevents uncalled-for air spring deflation or inflation while hoisting or jacking or towing occurs. Set the vehicle to the neutral gear slot on the hoisting device. The service on brake calipers requires removing brake caliper anchor plate bolts but leaving brake wheel hoses connected and tightening bolts to 190 Nm (140 ft-lbs) after installation. Extended suspension of the brake caliper using flexible brake hoses can lead to equipment damage. An assembly of the anchor plate and caliper should be removed and mechanic's wire should be used to support the caliper. You must remove both the access plug to the adjustment hole and contract the parking brake shoe before you can remove the brake disc if it binds with the shoe. To determine the brake disc's condition either choose resurfacing or use a new replacement depending on the results. The installation procedure should be reversed when completing the work.
Q: How to remove and replace the rear brake disc on Lincoln MKZ?
A: The first step toward brake disc change is to remove the wheel together with its tire. Position the parking brake lever in a backward direction to free up the brake caliper cable which can then be detached from its attachment point alongside the removal of the retaining clip from the cable conduit. Linked connections from the brake caliper should be removed before moving forward. Danger exists when allowing the brake caliper to dangle from the brake hose because this situation might result in brake damage. Set aside the brake caliper assembly with brake caliper anchor plate and brake pads by supporting it with mechanic's wire after removing its two anchor plate bolts. You should take out the two brake disc screws followed by the brake disc. The brake disc-to-hub mounting surface should be checked for rust and foreign material before installing with anti-seize lubricant applied. Stage in the new brake disc before tightening both screws to 20 Nm (15 lb-ft). After verifying there is no twist in the brake caliper hose position the brake caliper along with brake pads and brake caliper anchor plate assembly while tightening the two brake caliper anchor plate bolts to 70 Nm (52 lb-ft). The installation process requires you to reconnect the parking cable to the caliper followed by the lever adjustment before linking it to the parking brake lever. Also reinstall the cable conduit retaining clip. Put on the wheel together with the tire next, complete parking brake cycling to test normal functioning, and execute multiple brake operations to check proper brake performance.
