Tools You'll Likely Need:
* Wheel chocks: Essential for safety.
* Lug wrench: To remove the wheel.
* Jack and jack stands: To safely lift the vehicle.
* Screwdriver (usually a flathead): To adjust the star wheel.
* C-clamp or brake drum spreader: Helps to spread the brake shoes to access the adjuster. A large pair of pliers *might* work in a pinch, but a spreader is recommended.
* Socket wrench and sockets: Might be needed depending on the design of your wheel.
* Gloves: To keep your hands clean.
* Wrench (possibly): Some models may require a wrench for the adjuster.
Procedure (General - Consult your manual for specifics):
1. Safety First: Chock the front wheels, engage the parking brake, and safely raise the rear of the vehicle using a jack and secure it with jack stands. Never work under a car supported only by a jack.
2. Remove the Wheel: Remove the lug nuts and take off the wheel.
3. Access the Adjustment Mechanism: You'll see the brake drum. You'll likely need to use a C-clamp or brake drum spreader to gently spread the brake shoes apart enough to get the drum off. It might require some effort, but avoid using excessive force, as you could damage the shoes or other components. *This is the trickiest part; often you need to carefully manipulate the shoes.*
4. Locate the Adjuster: Inside the drum, you'll find a star-wheel adjuster. This is a small, notched wheel.
5. Adjust the Star Wheel: Using a screwdriver, turn the star wheel. Turning the star wheel clockwise tightens the brakes, counter-clockwise loosens them. You'll need to do this while carefully rotating the drum to feel for the proper clearance. You should feel a slight drag as the drum rotates. You want just enough resistance to prevent free spinning yet still allows the drum to turn freely without significant drag.
6. Check the Adjustment: Once you think you have the adjustment right, reassemble everything (drum, wheel, lug nuts). Test the brake pedal for firmness. It should feel firm, but not overly hard. If it feels too soft or spongy, recheck the adjustment.
7. Repeat for the other side: Follow the same steps for the other rear wheel.
8. Important Note: Don't over-tighten the adjuster. This can lead to dragging brakes, overheating, and premature wear. A small amount of clearance is needed for proper operation.
9. Test Drive: After reassembling everything, perform a test drive. Check for pulling or any unusual braking behavior.
When to Seek Professional Help:
If you're uncomfortable working on your brakes, take your car to a qualified mechanic. Brake adjustments are fairly simple, but improper adjustment can be very dangerous. If you encounter significant difficulty removing the drum or adjusting the brakes, it's best to seek professional assistance. Worn brake shoes or other brake components could be the reason for your brake adjustment issue. Replacing worn parts is an essential part of proper brake maintenance.
