How to Remove the Rear Brake Calipers on a Lincoln LSby Jody L. Campbell
Removing the rear calipers on a Lincoln LS is required if you're replacing the caliper, replacing the pads and or replacing the rotors. Having to replace the rear calipers is not a very common repair, but it does occur sometimes. Replacing the pads and rotors is more common, but to gain access to them, you'll need to disengage the caliper from the rear knuckle. The only time you need to remove the hydraulic brake line from the caliper is when you're replacing the caliper, however.
Do not apply the parking brake prior to lifting the Lincoln LS and attempting to remove the rear brake caliper(s). The parking brake is integrated with the rear caliper and applying it will prohibit you from removing the caliper.
Break the rear lug nuts loose on the rear wheel(s) with a wheel nut wrench.
Lift the rear axle of the LS with a jack and place it securely onto jack stands.
Remove the wheel nuts and wheel.
Place a brake line crimp on the rear brake hose to help prevent losing too much brake fluid.
Place a drain pan beneath the caliper where the brake hose connects to the caliper.

Disconnect the rear brake hose from the caliper. It will drip brake fluid slightly, so be sure to align the drain pan properly.
Disengage the parking brake cable from the cam of the brake caliper using a pair of pliers.
Remove the two caliper guide bolts from the caliper and then pry if off the rear pads and rotor. Be careful, as brake fluid will still purge from the brake hose connection.
If desired, remove the pads from the caliper anchor and then remove the two caliper anchor bolts from the rear of the backing plate and knuckle.
- Bleeding the brake lines will be required any time you disconnect the brake hose from a caliper. The use of the brake line crimps is to avoid losing too much brake fluid during the procedure, but it will not prevent air from getting into the hydraulic system. Bleeding the air from the system to restore the disc braking system will be required. A caliper piston reset tool will also be required if you're replacing the same caliper. This tool using the suitable adapter will screw the rear piston inward in a clockwise fashion. New calipers will come with the pistons already compressed. To seat the pistons properly to the pads and rotors, you will need to pump the foot brake pedal during the bleeding procedure before attempting to drive the Lincoln.
