Adjusting Padking Brake with 4 wheel disc brakes.

If your parking brake is too loose or is not properly adjusted, you may encounter problems while parking, positioning and driving your car. Most of the time, car owners would send their car to a mechanic in order to fix and tighten the parking brake. However, you can actually skip this step and adjust your parking brake yourself. When your car starts to slip on a hill in its park position, you need to start tightening the parking brake.1 Remove the car's center console cover placed around your parking brake level inside your car. This is found between the seat of the driver and the front passenger.2 Use your wrench to turn its adjuster nut found at the end of your parking brake's cable rod. Loosen the adjuster nut with your wrench, while making sure that it does not come off at your parking brake cable rod's end.3 Raise your car rear wheels using your jack, and use your jack stands to support both its rear wheels.4 Pull up your parking brake handle up to two clicks or notches. Tighten your adjuster nut until you feel a slight resistance on your rear wheels whenever you spin them.5 Release your parking brake lever. Check and make sure that your rear wheels are still able to spin freely and without any resistance.6 Pull up on your parking brake lever up to three to five clicks or notches, while making sure that your car's rear wheels are not turning at all.7 Lower the car by adjusting your jack, and remove your jack stands from your car's rear wheels.

your rear brakes are worn or the self adjusters are rusted, assuming you have drum rear brakes & not disc pads in the rear.
Try backing up several times with very hard stops to activate the self adjusters. If you don't back up much, the self adjusters can not work. Parking brake will be adjusted at the same time.

The only manual adjustment for the parking brake on these is at the shoes themselves. Procedure for that is as follows:

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

under the car/truck the cable if your truck has 4 wheel disc brakes then the parking brake my be self adjusting / with parking brake shoes in the new style there is an adjustment on the back wheels

The parking brake on most vehicles are self adjusting. If the parking brake is not self adjusting you will to remove the brake drum/rotor and check to see which part is binding. If you wan to simply adjust the parking brake lever to make it tighter there should be an adjusting nut on the cable under the vehicle.

Shoes Removal

Take a picture and remember how each part goes and attaches

1. Remove the brake drum, refer to Drum in this section.

1. Remove the upper retracting spring.

1. Remove the lower retracting spring.

1. Remove the self-adjuster.

1. Remove the hold-down springs.

1. Remove the parking brake lever clip and the parking brake lever.

The adjuster is just like on a car with drum brakes. It can be adjusted with the wheels still on the truck, but if yours is out enough that it doesn't work, an inspection is warranted. Axle seal failure is common and will soak the shoes.

Jacked both rear wheels off ground, and while slowly spinning wheel, tighten the star-wheel adjuster until you just hear and feel brake drums rubbing, then loosened slightly.
There's a plastic dust cover about 1/4" X 1" that you remove, and use a drum brake adjuster tool.

The driverside access hole is below axle, easily accessable. To tighten driver side rear parking brake, turn star-wheel adjuster down.


The passengerside access hole is found above axle, and difficult to see. Removed pass side wheel and used an inspection mirror.
To tighten passenger side rear parking brake, turn star-wheel adjuster up.

Good luck and hope this helps. Oh and the other thing to is that if you do smell axle fluid around the wheels and see oil leaking from the drum area. Then you have a axle wheel seal and or bearing gone bad too.

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 .

Hi... to adjust rear brakes providing the shoes are good... just drive vehicle in reverse and pump brakes... rear shoes are self adjusting so they should "adjust" themselves... after doing this test by putting on park brake, put vehicle in drive and see if vehicle moves forward, repeat procedure if necessary. Hope this helps... please rate suggestion.... ty
