How to Change Drum Brakes on a Trailer

Maintaining your trailer is crucial to ensuring safety and performance on the road. One essential maintenance task is changing the drum brakes, which are vital for stopping your trailer efficiently. This guide will walk you through the process of changing drum brakes on a trailer step-by-step, helping you keep your vehicle in peak condition.

Tools and Materials Needed

Before beginning the process, gather the necessary tools and materials

- Jack and jack stands - Lug wrench - Socket set - Screwdrivers (flat-head and Phillips) - Brake cleaner - New brake shoes and drums - Brake grease - Safety glasses and gloves - Dust mask (optional)

Step 1 Prepare the Trailer

1. Safety First Park your trailer on a flat surface and engage the trailer's parking brake. Use wheel chocks to secure the tires to prevent any movement during the process. 2. Loosen the Lug Nuts Before raising the trailer, use the lug wrench to slightly loosen the lug nuts on the wheel you will be working on, but do not remove them completely.

Step 2 Raise the Trailer

1. Jack Up the Trailer Carefully place the jack under the trailer’s frame and lift it until the wheel is off the ground.

2. Secure with Jack Stands Once the trailer is raised, place jack stands beneath the frame for added safety.

3. Remove the Wheel Completely remove the loosened lug nuts and take off the wheel to expose the drum brake assembly.

Step 3 Remove the Brake Drum

1. Inspect the Drum Check for any damage or excessive wear. If the drum has grooves or cracks, it is advisable to replace it.

2. Remove the Retaining Hardware Look for the retaining screws or clips that hold the brake drum in place. Use the appropriate screwdriver or socket to remove these components.

3. Pull Off the Drum Gently pull the brake drum off the wheel hub. If it is stuck, tap it lightly with a rubber mallet to loosen it.

Step 4 Change the Brake Shoes

1. Inspect the Brake Assembly Before replacing the shoes, inspect all components like the springs, actuators, and wheel cylinders for any signs of wear or damage.

2. Remove Old Brake Shoes You'll find springs and retainers securing the brake shoes. Use your tools to remove these components carefully, being mindful of their spring tension.

3. Install New Brake Shoes Position the new brake shoes into the assembly. Make sure they align correctly with the wheel cylinder and the backing plate. Reattach the springs and retainers securely.

Step 5 Reassemble the Drum Brake

1. Clean the Brake Components Use brake cleaner to clean the drum and remove any debris or dust from the assembly.

2. Reattach the Brake Drum Once the shoes are in place, slide the brake drum back onto the wheel hub. Secure it with the retaining screws or clips.

3. Reinstall the Wheel Place the wheel back onto the hub, lining it up with the lug bolts. Hand-tighten the lug nuts before lowering the trailer.

Step 6 Lower the Trailer and Test

1. Lower the Trailer Carefully remove the jack stands and lower the trailer back to the ground. Torque the lug nuts to the manufacturer’s specifications using the lug wrench.

2. Test the Brakes Before taking your trailer on the road, perform a brake test. This can be done by slowly rolling the trailer forward and applying the brakes to ensure they function correctly.

Conclusion

Changing drum brakes on your trailer is a task that requires attention to detail but can be done with some basic tools and knowledge. Regular maintenance, including brake changes, is key to ensuring a safe and reliable towing experience. Always consult your trailer's owner manual for specific instructions and safety precautions. If you're ever in doubt, don't hesitate to seek professional assistance. With proper care, your trailer will provide many safe journeys ahead.
