How to Tighten Rear Drum Brakes

Maintaining your vehicle’s braking system is crucial for safety and performance. Rear drum brakes, while not as common as disc brakes in newer vehicles, are still found in many models. Over time, these brakes can become loose or malfunction due to wear and tear. This can lead to inefficient braking and increased stopping distances, which can be dangerous. Here’s a comprehensive guide on how to tighten rear drum brakes effectively.

Tools and Materials Needed

Before you start, gather the necessary tools a jack and jack stands, a lug wrench, a brake adjusting tool or screwdriver, and possibly some brake cleaner. It’s also advisable to wear safety glasses and gloves.

Step 1 Preparing Your Vehicle

Begin by ensuring the car is parked on a level surface. Engage the parking brake to prevent any movement. Loosen the lug nuts on the rear wheels slightly but do not remove them completely. Use your jack to lift the vehicle, and then support it securely with jack stands. Remove the rear wheels to access the drum brakes.

Step 2 Inspect the Brake Components

Once the wheels are off, take a moment to inspect the brake components. Look for any visible signs of wear, such as cracked or worn brake shoes. If they appear excessively worn, consider replacing them instead of merely adjusting the brakes.

Step 3 Locate the Brake Adjuster

Drum brakes typically have an adjusting mechanism located at the bottom of the brake assembly. This is usually a star wheel that can be turned to adjust the brake shoes' position. You may need to use a flashlight to get a better view.

Step 4 Adjusting the Brake Shoes

Using a brake adjusting tool or a flat-head screwdriver, rotate the star wheel. Turn it in the direction indicated for tightening (usually clockwise, but check your vehicle’s service manual). This action will move the brake shoes outward, bringing them closer to the drum. Adjust them until you feel a slight drag when rotating the drum by hand; this means they’re properly aligned.

Step 5 Reassembling the Brakes

After making the adjustment, check that everything is secure. Replace the drum and reinstall the wheel, tightening the lug nuts by hand. Lower the vehicle back to the ground.

Step 6 Final Checks

Once the car is back on the ground, fully tighten the lug nuts in a star pattern to ensure even pressure. Pump the brake pedal a few times to help the shoes settle against the drum. Finally, take your vehicle for a short test drive to ensure the brakes are functioning properly.

In conclusion, tightening rear drum brakes is a straightforward process that can significantly enhance your vehicle's safety. Regular maintenance checks and timely adjustments will contribute to better braking efficiency and a longer lifespan for your brake components. Always consult your vehicle's manual for specific instructions related to your make and model, and don’t hesitate to seek professional assistance if you’re unsure about any steps.
