How to loosen the parking brake to reinstall the parking brake cable on the rear calipers of a 1977 lincoln mark v

• Adjustments

1. Apply service brake pedal three times with a force of approximately 175 lbs.



2. Fully apply and release parking brake three times. Full application may require two pedal strokes.



3. Raise and support vehicle, then mark relationship between wheel and axle flange.



4. Check parking brake pedal assembly for full release as follows:

1. Turn ignition switch to On position.



2. If ``Brake\'\' lamp is illuminated, operate manual brake release and pull downward on front parking brake cable to remove slack from pedal assembly.

1. Remove rear wheel and tire assemblies, then install two lug nuts to retain each rotor assembly.



2. If two parking brake levers on both calipers are not against lever stops on caliper housings, check for binding in rear cables and/or loosen cables at adjuster until both left and right levers are against their stops.



3. Tighten parking brake cable at adjuster until either the left or right lever begins to move off the stop, then loosen adjustment until lever moves back barely touching stop.



4. Operate parking brake several times to check adjustments. A firm pedal feel should be obtained by pumping pedal two full strokes and rear wheels should not rotate forward when parking brake is fully applied.



5. Install wheel and tire assemblies, aligning marks made in step 3.

Remove the center console covering the parking brake lever. Locate the parking brake lever between the drivers seat and the front passenger seat. Put the parking brake lever in the lowest position.

2

Turn the cable adjuster locknut to make the nut loose. Find the nut at the base of the parking brake lever.

3

Raise your GT rear wheels using a jack and support the rear wheels using jack stands. Remove both rear wheels using a tire iron to loosen and take off the lug nuts. Take off the tire from the rods by hand.

4

Get underneath the car and remove the rubber hole plugs from the brake rotors. Locate the rotors on the underneath inside of the wheel wells.

5

Take off the brake calipers with a screwdriver, but do not disconnect the brake fluid lines.

6

Use a pry bar to push up on the parking brake self adjuster wheel. Locate this next to the brake caliper and it looks like a star wheel. Rotate this wheel until the rotors will not turn.

7

Turn the adjuster wheel five notches in the opposite direction. Reinstall the calipers and wheels. Lower your GT using the jack and remove the jack stands from the rear wheels.

If it is like my 2004 LS ,you just hook the end of the
parking cable over the notch in the caliper parking
brake arm

Brake Caliper - Removal & Installation

CAUTION Dust and dirt accumulating on brake parts during normal use may contain asbestos fibers from production or aftermarket brake linings. Breathing excessive concentrations of asbestos fibers can cause serious bodily harm. Exercise care when servicing brake parts. Do not sand or grind brake lining unless equipment used is designed to contain the dust residue. Do not clean brake parts with compressed air or by dry brushing. Cleaning should be done by dampening the brake components with a fine mist of water, then wiping the brake components clean with a dampened cloth. Dispose of cloth and all residue containing asbestos fibers in an impermeable container with the appropriate label. Follow practices prescribed by the Occupational Safety and Health Administration (OSHA) and the Environmental Protection Agency (EPA) for the handling, processing, and disposing of dust or debris that may contain asbestos fibers.
Inspect the fluid level in the brake master cylinder reservoir. If the brake fluid level is midway between the maximum-full point and the minimum allowable level, no brake fluid needs to be removed from the reservoir before proceeding. If the brake fluid level is higher than midway between the maximum-full point and the minimum allowable level, remove brake fluid to the midway point before proceeding.

1. Raise the vehicle and suitably support.
2. Remove the tire and wheel assembly.
3. Pull down on the front park brake cable.
4. Remove the front park brake cable from the park brake cable connector.
   NOTE When using a large C-clamp to compress a caliper piston into a caliper bore of a caliper equipped with an integral park brake mechanism, do not exceed more than 1 mm (0.039 in.) of piston travel. Exceeding this amount of piston travel will cause damage to the internal adjusting mechanism and/or the integral park brake mechanism.
5. Install a large C-clamp over the top of the brake caliper housing and against the back of the outboard brake pad. Compress the brake caliper piston into brake caliper bore to allow the piston enough clearance to slide the brake caliper off the brake rotor.

Hope helps (remember rated this).

not adjusted correctly , sould be able to adjustswitch under hand brake boot

Hope this helps. This is out of the factory manual. Let me know if this works for you.
PARKING BRAKE NOTE: Tensioner adjustment is only necessary when the tensioner, or a cable has been replaced or disconnected for service. When adjustment is necessary, perform adjustment only as described in the following procedure. This is necessary to avoid faulty park brake operation.

1. Raise vehicle.
2. Fully back off cable tensioner adjusting nut at equalizer to create slack in cables.
3. Remove rear wheel/tire assemblies. Remove brake calipers and rotors.
4. Verify park brakes are in good condition and operating properly.
5. Verify park brake cables operate freely and are not binding, or seized.
6. Check park brake shoe adjustment.
7. Reinstall rotors and make sure rotors turn freely.
8. Reinstall brake calipers. Tighten guide pin bolts to 41 n·m (30 ft.lbs.)
9. Reinstall wheel/tire assemblies after brake shoe adjustment is complete.
10. Lower vehicle enough for access to park brake foot pedal. Fully apply park brakes

NOTE: Leave park brakes applied until adjustment is complete.

1. Raise vehicle again.
2. Mark tensioner rod 6.35 mm (1/4 in.) from edge of tensioner bracket Adjustment Mark On Cable Tensioner Rod
3. Tighten adjusting nut at equalizer until mark on tensioner rod moves into alignment with tensioner bracket

CAUTION: Do not loosen, or tighten the tensioner adjusting nut for any reason after completing adjustment.

1. Lower vehicle until rear wheels are 15-20 cm (6-8 in.) off shop floor.
2. Release park brake foot pedal and verify that rear wheels rotate freely without drag. Verify pedal returns to fully released position.
3. Lower the vehicle

I changed the rear pads this fall, have you removed the caliper retaining bolts and the Park Brake Cable? I remember the cable being a pain and using a large hammer and pry bar to loosen the caliper. You can pry on the edge of the pad and the hat section of the rotor. The rear rotors aren't expensive and should be done at the same time.

Screw in rear caliper pistons. Install pads and caliper,then ratchet up parking brake by hand, at caliper. No electric or cable issues involved
