How to Adjust Brake Drum Shoes

Adjusting brake drum shoes is an essential maintenance task that helps ensure your vehicle’s braking system operates efficiently. Over time, the brake shoes can wear down and lose their effectiveness, leading to decreased braking performance and safety risks. Here’s a step-by-step guide on how to properly adjust your brake drum shoes.

Tools and Materials Needed

Before you begin, gather the necessary tools a jack and jack stands, a lug wrench, a brake shoe adjusting tool (or a flat screwdriver), and possibly a brake cleaner. It is also beneficial to have a shop manual for your vehicle for any specific recommendations regarding your model.

Step 1 Safety First

Start by parking your vehicle on a flat surface and engaging the parking brake. Loosen the lug nuts on the rear wheels slightly before raising the vehicle with a jack. Once lifted, securely place jack stands under the vehicle to ensure it remains stable during the adjustment.

Step 2 Remove the Wheel

Remove the lug nuts completely and take off the wheel to access the brake drum. Inspect the condition of the drum and shoes—look for uneven wear or any signs of damage.

In some cases, the brake drum may be stuck due to rust or debris. If so, gently tap it with a rubber or plastic mallet to loosen it. Once removed, inspect the inner surface for wear, and clean any dust or debris using brake cleaner.

Step 4 Inspect the Brake Shoes

Check the condition of the brake shoes. If they appear worn down or unevenly, consider replacing them. If they are still in good condition, proceed to adjust them.

Step 5 Adjust Brake Shoes

Locate the adjusting wheel or star wheel within the brake assembly. You will typically find it between the two brake shoes. Using your brake shoe adjusting tool or a flat screwdriver, turn the wheel until the shoes are snug against the drum. Ensure there is a slight space so that the drum can rotate smoothly without dragging.

Step 6 Reassemble and Test

Once the adjustment is complete, reattach the brake drum, ensuring it is secure. Replace the wheel and hand-tighten the lug nuts before lowering the vehicle. After lowering, tighten the lug nuts fully in a star pattern to ensure even seating.

Step 7 Test the Brakes

With the vehicle on the ground, repeat the process on the other side if needed. Finally, start the vehicle and gently test the brakes at low speed in a safe environment to ensure they function correctly.

Properly adjusted brake shoes are crucial for your vehicle's braking efficiency. Regular maintenance can save you time, money, and enhance your safety on the road. Always consult your vehicle's manual for specific instructions related to your brake system.
