The Importance of Adjusting the Drum Brake
The drum brake is a complex system that relies on precise alignment and adjustment to function properly. If the brake shoes are not properly adjusted, they may not make contact with the drum, leading to reduced braking performance. Additionally, if the brake shoes are over-adjusted, they may wear out prematurely, leading to costly repairs. Adjusting the drum brake is a critical maintenance task that can help prevent these issues and ensure the safety and reliability of the vehicle.
Tools and Materials Needed
To adjust the drum brake, you will need the following tools and materials:
- A drum brake adjustment tool (available at most auto parts stores)
- A pair of gloves
- A pair of safety glasses
- A torque wrench
- A socket wrench
- A ratchet
- A drum brake lubricant (optional)
Step-by-Step Instructions
Adjusting the drum brake is a relatively straightforward process that can be completed in a few hours. Here are the step-by-step instructions:
Step 1: Jack Up the Vehicle
Before starting the adjustment process, you will need to jack up the vehicle to give you clearance to access the drum brake. Make sure the vehicle is securely supported by jack stands and that the parking brake is engaged.
Step 2: Remove the Wheel

Step 3: Remove the Brake Dust Shield
The brake dust shield is a protective cover that helps keep debris out of the drum brake. To access the brake shoes, you will need to remove the dust shield. This can usually be done by unscrewing the retaining clips and sliding the shield off.
Step 4: Inspect the Brake Shoes
Once the dust shield is removed, you can inspect the brake shoes for wear and damage. Look for any signs of wear or damage, such as rust or corrosion, and make a note of any issues you find.
Step 5: Adjust the Brake Shoes
To adjust the brake shoes, you will need to use the drum brake adjustment tool. This tool is designed to help you adjust the brake shoes to the correct position. Follow the manufacturer’s instructions for adjusting the brake shoes, and make sure to check the brake shoes frequently to ensure they are properly aligned.
Step 6: Reassemble the Drum Brake
Once the brake shoes are adjusted, you can reassemble the drum brake. Make sure to tighten all the retaining clips and bolts securely, and check the brake shoes one last time to ensure they are properly aligned.
Step 7: Bleed the Brake System
Finally, you will need to bleed the brake system to remove any air that may have entered the system during the adjustment process. This can usually be done by using a brake bleeding kit and following the manufacturer’s instructions. (See Also: What Would Cause Brake Caliper to Stick? Common Culprits Revealed)
