How to Adjust Parking Brake Shoes
This guide will walk you through the process of adjusting your parking brake shoes. While the specific steps may vary slightly depending on your vehicle model, the general principles remain the same. It’s important to consult your vehicle’s owner’s manual for detailed instructions and torque specifications specific to your car.

How To Adjust Parking Brake Shoes
The parking brake, also known as the handbrake, is a crucial safety feature in any vehicle. It prevents your car from rolling when parked on an incline or flat surface. Over time, the parking brake shoes may wear down, requiring adjustment to maintain optimal braking performance. This article will guide you through the process of adjusting parking brake shoes, empowering you to handle this essential maintenance task yourself.
Understanding Parking Brake Systems
Most vehicles utilize a mechanical parking brake system. This system involves brake shoes that press against a drum brake rotor located on each rear wheel. When you engage the parking brake, a lever or cable system pulls the shoes outward, creating friction and stopping the wheels.
Components of a Parking Brake System
- Parking Brake Lever: The lever you pull to engage the parking brake.
- Cable System: A series of cables that transmit force from the lever to the brake shoes.
- Brake Shoes: Friction pads that press against the brake drum.
- Brake Drum: A metal cylinder attached to the rear wheel hub.
- Adjusting Mechanism: A system of star wheels or other components that allow you to adjust the shoe clearance.
Signs Your Parking Brake Needs Adjustment
Pay attention to these signs that indicate your parking brake may require adjustment:
- The parking brake lever feels loose or spongy.
- The vehicle rolls when parked on an incline.
- You need to pull the lever all the way up to engage the brake.
- You hear grinding or squealing noises when applying the parking brake.
Tools and Materials You’ll Need
Before you begin, gather the following tools and materials:
- Socket wrench set
- Screwdriver
- C-clamp or brake shoe adjuster tool
- Lug wrench
- Jack and jack stands
- Gloves
Step-by-Step Guide to Adjusting Parking Brake Shoes
Follow these steps carefully to adjust your parking brake shoes:
1. Secure the Vehicle
Park your vehicle on a level surface and engage the parking brake. Chock the front wheels to prevent the vehicle from rolling.
2. Loosen the Lug Nuts
Using a lug wrench, loosen the lug nuts on the rear wheels. Do not remove them completely at this stage.
3. Raise the Vehicle
Using a jack, carefully raise the vehicle until the rear wheels are off the ground. Securely position jack stands under the vehicle frame to support its weight.
4. Remove the Wheel
Now, completely remove the lug nuts and take off the rear wheel.
5. Access the Brake Drum
Locate the brake drum on the rear axle. It may be held in place by a few bolts or clips. Remove these fasteners to access the drum.
6. Inspect the Brake Shoes
Carefully remove the brake drum. Inspect the brake shoes for wear and tear. If they are excessively worn, you will need to replace them before adjusting the parking brake.
7. Adjust the Parking Brake Shoes
Locate the adjusting mechanism on the back plate of the brake assembly. This mechanism is typically a star wheel or a similar component. Use a screwdriver or a specialized brake shoe adjuster tool to turn the adjusting mechanism.
Turning the adjusting mechanism will move the brake shoes outward, increasing the braking pressure.
8. Test the Parking Brake
Reinstall the brake drum and wheel. Lower the vehicle and test the parking brake. Engage the lever and make sure the wheel does not rotate.
If the wheel still rotates, continue to adjust the parking brake shoes in small increments until the desired braking pressure is achieved.
9. Fine-Tune the Adjustment
Once the parking brake is functioning properly, you may need to fine-tune the adjustment.
Engage the parking brake and apply a slight force to the wheel. If you feel excessive resistance, loosen the adjustment slightly. If the wheel still rotates, tighten the adjustment.
10. Repeat for the Other Wheel
Repeat steps 4 through 9 for the other rear wheel.
Safety Precautions
When working on your vehicle’s brakes, always prioritize safety:
- Wear gloves to protect your hands from dirt and grime.
- Use jack stands to securely support the vehicle when it is raised.
- Never work under a vehicle that is only supported by a jack.
- Be aware of moving parts and potential hazards.
