If you look at the bottom of the rear brake drum you should find a little opening sometimes it has a rubber plug inserted in it. Pull out the plug and use a thin straight screwdriver to feel for the adjuster. The adjuster has a spoked wheel on it thatyou can turn with the screwdriver just turn it a couple of clicks at a time till you feel drag on the wheel whenyou turn it by hand.

How to adjust parking brake on 1993 chevy lumina ?

  • 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.

    How to adjust rear brakes on toyota coaster

    There are usually two ways to go about adjusting the rear brakes, both involve getting the rear wheels off the ground on jack stands. Look for a small oval shaped rubber plug near the top on the brake backing plate where the brake line goes, there is a star adjuster wheel inside, with screwdriver rotate the wheel upward, there will be a clicking noise, ecah click tightens the brake, rotate the wheel while doing this until the wheel has a slight drag while rotating then stop. The other whay is to remove the wheel and the brake drum, then adjust the star adjuster a little at a time until the brake drums just fits over the brake shoes.

    Adjusting the parking brake on a MiTSubichi ENDEAVOUR 2005

    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.

    Rear brakes sticking

    need more info---did you have brakes worked on, did it happen all of a sudden???

    I changed the rear brake pads and the rotor and rim are getting very very hot.

    Are the rear brakes drum? If so they need to be adjusted. There is a little slot on the backside of the brake assembly that usually has a plastic or rubber cover. Jack the rear end up and remove that cover to expose a little slot. Use a small flathead screwdriver to adjust the ratchet mechanism. To find out which way to turn it spin the wheel occasionally to see what direction will tighten the shoes. Adjust the shoes untill the wheel stops spinning then back off a turn.

    Adjust handbrake on nissan terrano

    On the inboard side of the rear wheel hubs, you will find an oval rubber plug, pry this plug out, to gain access to the brake adjuster.
    Pull the handbrake up two clicks.
    Jack and support. Remove the rear wheel, and adjust the brake using a screw driver levered through the slot to turn the notched wheel of the adjuster, until the hub starts to drag when rotated by hand. Repeat for the other side. Note the ratchet mechanism on the adjuster will only let it turn one way.

    Need to adjust rear brakes

    Most cars have self adjusting brakes. Simply back up while applying the brake. If this doesny work. Jack up the car so you can turn the wheel, you should see a rubber plug which I refer to as a dust cover. Remove this and using a brake adjusting tool move the adjusting sccrew up or down until you feel some pressure on the wheel when you turn it. Then back off a turn.

    How to adjust parking brake on a GMC Sierra 2500 HD Duramax 4wd?

    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.
