How to Change Drum Brakes
Changing drum brakes can seem like a daunting task, but with the right tools and a little bit of guidance, it can be a manageable DIY project. Drum brakes are commonly used in older vehicles and can require maintenance just like disc brakes. Here’s a step-by-step guide on how to change drum brakes, ensuring your vehicle runs safely and smoothly.
Tools and Materials Needed
Before you get started, gather the necessary tools and materials. You’ll need
- Lug wrench - Jack and jack stands - Brake cleaner - Drum brake kit (shoes, springs, clips) - Screwdrivers - Pliers - A work light (if you're working in dim conditions) - Safety glasses and gloves
Step 1 Prepare Your Vehicle
First, ensure your vehicle is on a flat, stable surface. Engage the parking brake and place wheel chocks behind the front wheels for added safety. Using the lug wrench, loosen but do not completely remove the lug nuts on the rear wheels while the vehicle is still on the ground.
Step 2 Lift the Vehicle
Once the lug nuts are loosened, use the jack to lift the vehicle. After lifting, securely position jack stands under the vehicle to prevent it from collapsing. Now, you can completely remove the lug nuts and take off the wheel to expose the drum brake assembly.
Step 3 Remove the Brake Drum
With the wheel removed, you should see the brake drum. To remove it, you may need to tap it with a hammer if it is stuck due to rust or brake material buildup. If your vehicle has a retaining screw on the drum, make sure to remove this first. Once loose, gently pull the drum off the wheel hub, taking care not to damage any components behind it.
Step 4 Inspect the Components
With the drum removed, take a moment to inspect the condition of the brake shoes, springs, and other components. Look for signs of wear, such as uneven wear on the brake shoes, or any broken springs. Taking a picture or drawing a diagram can help you understand how to reassemble everything later.
Step 5 Remove the Old Brake Shoes
Start removing the old brake shoes by detaching the return springs. Use a pair of pliers to unhook them. Then, using a screwdriver, flip the anchor pin or adjuster, which will allow you to remove the shoes. Take note of how everything is arranged, as you’ll need to replicate this setup with the new components.
Step 6 Install the New Brake Shoes
Before installing the new shoes, clean the brake assembly using the brake cleaner to remove dust and debris. Install the new brake shoes by following the same arrangement as the old ones. Ensure that the adjuster and the springs are correctly positioned.
Step 7 Reattach the Brake Drum
Once the new shoes are firmly in place, carefully slide the brake drum back onto the wheel hub. Ensure it moves smoothly and fits properly without excessive play.
Step 8 Reinstall the Wheel
Align the wheel back on, and hand-tighten the lug nuts. Lower the vehicle by removing the jack stands and lowering it to the ground. Once the vehicle is on the ground, use the lug wrench to tighten the lug nuts in a crisscross pattern to ensure even tightening.
Step 9 Test the Brakes
Before taking your vehicle back on the road, pump the brakes a few times to ensure they’re functioning properly. This helps to set the shoes against the drum and ensures that your braking system is responsive.
Conclusion
Changing drum brakes is a valuable skill that can save you money and keep your vehicle in top working condition. Always remember to wear safety gear, and if you encounter any issues or feel overwhelmed, it’s perfectly okay to consult a professional mechanic. Regular maintenance will prolong the life of your brakes and ensure a safer driving experience. Happy wrenching!
