Parking Brake doesn't work. I have adjusted the

• 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.

Over here we call it a parking brake - hardly any of our cars are autos.

Parking brakes usually connect to the rear disc brake calipers but some manufacturers use a small drum brake in the disc centre for parking purposes due to the complexity of the caliper with integral parking brake.

When adjusting a parking brake it is important in most designs for the cable to be adjusted only to remove any free play without moving the caliper levers from the backstops and then if the parking brake lever or pedal travel is excessive it must be because of wear or other faults. Sometimes that basic requirement must be taken with a pinch or two of "experienced" salt...

Ford have a self adjusting parking brake I have experience of. A spring within the system preloads the cable eliminating all slack in the cable so the cable moves the caliper levers from the first. The main problem with the system is the preload spring is sometimes strong enough to overcome the resistance of the caliper spring and cause a binding brake. No manual adjustment was provided.
In that case I find fabricating and fitting brackets to anchor additional return springs to the calipers is a must.

Under the car on the drivers side you will see a threaded rod that goes through a saddle that goes off with two cables to the rear wheels, adjust the cable there using the adjustment nut.

Adjustment

1. Place parking brake lever in -full released- position.
2. Raise and support vehicle.
3. Remove plug in parking brake shoe support to access adjuster star-wheel.
4. Through the access hole, rotate the adjuster star wheel in the following direction to expand the shoes outward against the drum:
   1. Left brake - Rotate star-wheel toward rear of vehicle.
   2. Right brake - Rotate star-wheel toward front of vehicle.
5. Using an appropriate tool, turn adjuster star wheel until wheel will not rotate (dead lock).
6. Back off adjuster six detents (teeth).
7. Rotate wheel, checking for light drag. If drag is too heavy, continue to back off adjuster one detent at a time until light drag is present. Do not back off star-wheel more than 17 detents from wheel lock.
8. Install access plug.
9. Adjust opposite wheel parking brake shoes using same method.
10. Lower vehicle.
11. Apply and release parking brake lever once to ensure proper operation of parking brakes.

Removal & Installation NOTE The following procedure may be used to remove shoes on either side of the vehicle.

1. Lock out automatic adjuster in parking brake lever.
2. Raise and support vehicle.
3. Access and remove rear hub and bearing.
4. Remove parking brake cable bolt at knuckle.
5. Completely back off parking brake shoe adjustment.
6. Remove parking brake shoe adjuster spring.
7. Remove shoe adjuster.
8. Remove upper brake shoe hold-down clip and pin.
9. Remove lower brake shoe hold-down clip and pin.
10. Remove upper and lower shoes with return spring from shoe actuator.
11. Remove return spring from shoes.

To install:

1. Install return spring between upper and lower shoes.
   NOTE Before installing shoes on actuator, make sure actuator hooked to rear cable is positioned with word -UP- facing outward.
2. Install upper and lower shoes with return spring on shoe actuator located on parking brake cable.
3. Install lower brake shoe hold-down pin through rear of support and lower shoe, then install hold-down clip.
4. Install upper brake shoe hold-down pin through rear of support and upper shoe, then install hold-down clip.
5. Install shoe adjuster. Place end of adjuster with star wheel upward.
6. Install parking brake shoe adjuster spring.
7. Install bolt securing parking brake cable to knuckle and tighten bolt to 21 ft. lbs. (28 Nm).
8. Using Brake Shoe Gauge, Special Tool C-3919, or equivalent, measure inside diameter of parking brake drum portion of rotor.
9. Place Gauge over parking brake shoes at widest point.
10. Using adjuster star wheel, adjust parking brake shoes until linings on both park brake shoes just touch jaws on gauge. This will give a good preliminary adjustment of parking brake shoes, before a final adjustment is made at end of this procedure.
11. Install hub and bearing with wheel speed sensor as well as all components necessary to access it.
12. Lower vehicle.
13. Unlock automatic adjuster in parking brake lever.
14. Perform final adjustment of parking brake shoes

Hi:
You could have a parking brake cable sticking, or just your rear brake is over adjusted. Rear brakes can be adjusted in, and after the rear drum is removed, the parking brake cable should be checked to see if it moves in and out. Replace if needed!

you mean parking brake cable? loosen parking brake cables put drums on , and adjust shoes till they lightly drag, now apply brakes a few times and check the adjustment again, if all ok, now adjust park brake cables, you want to adjust so park pedal goes 5-8 clicks till the wheels are "locked up" and the wheels spin free with the park brake off

The rear drum brakes:

• Have internal shoes that expand against the brake drum (1126).
• Are a single-anchor type.
• Are actuated by one rear wheel cylinder (2262).
• Have two pistons in the rear wheel cylinder (2261). One exerts force against the upper end of the primary shoe; the other exerts force against the upper end of the secondary shoe.
• Adjust rear brake shoes and linings (2200) automatically.
• Need manual brake adjustment if the adjusters are not operating properly or after the rear brake shoes and linings have been replaced.

When the brake pedal is applied, hydraulic fluid pressure forces the pistons in the rear wheel cylinder outward, moving the rear brake shoes and linings against the brake drum.
The rear drum brake system includes the parking brake mechanism. Refer to Section 206-05 .

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

Check the return spring on the parking brake lever as wll as the gear teeth:

1. Make sure the parking brake cable is free and is not frozen or sticking. Make sure the brake shoes are properly adjusted.
2. Raise and safely support the rear wheels.
3. Apply the parking brake while counting the number of notches. Check the desired parking brake stroke; it should be 7-9 notches.
4. If adjustment is required, remove the adjusting nut cover and turn the adjusting nut located at the front of the parking brake cable.
5. After adjustment, check there is no looseness between the adjusting nut and the parking brake lever, then tighten the locknut.

Do not adjust the parking brake too tight. If the number of notches is less than specification, the cable has been pulled too much and the automatic adjuster will fail or the brakes will drag.

1. With the parking brake lever in the released position, turn the rear wheels to confirm that the rear brakes are not dragging.
2. Lower the vehicle.
3. Check that the parking brake holds the vehicle on an incline.
