How to Change Brake Drums
Changing brake drums is a necessary skill for any car owner or enthusiast who wishes to maintain their vehicle’s braking system. Brake drums work in conjunction with brake shoes to create the friction needed to slow down or stop your vehicle. Over time, these components can wear out, and it’s essential to know how to change them to ensure your safety on the road. This article will guide you through the steps necessary to change your brake drums effectively.
Tools and Materials Needed
Before you begin, gather the following tools and materials
1. A jack and jack stands 2. Lug wrench 3. Brake drum puller (if necessary) 4. Screwdrivers (flathead and Phillips) 5. New brake drums 6. Brake shoe kit (if needed) 7. Brake cleaner 8. Ratchet and socket set 9. Gloves and safety goggles
Step 1 Safety First
Always prioritize safety when working on your vehicle. Begin by parking your car on a flat, stable surface and engaging the parking brake. Wear safety goggles and gloves to protect your eyes and hands from debris and oil.
Step 2 Loosen the Lug Nuts
Using a lug wrench, slightly loosen the lug nuts on the wheel corresponding to the brake drum you wish to replace. It’s easier to do this while the wheel is still on the ground. Do not completely remove the lug nuts yet.
Step 3 Lift the Vehicle
Once the lug nuts are loosened, use a jack to lift the vehicle. Place jack stands under the car for added safety to ensure that the vehicle remains stable while you work.
Step 4 Remove the Wheel
With the vehicle securely lifted, fully remove the loosened lug nuts and take off the wheel. Set the wheel aside in a safe location.
Step 5 Remove the Brake Drum
Inspect the brake drum for any retaining screws. If there are screws, use the appropriate screwdriver to remove them. Depending on the model of your vehicle, the drum may simply slide off. However, if it is stuck due to rust or wear, you may need a brake drum puller to remove it. Once the drum is free, gently pull it away from the axle.
Step 6 Inspect and Replace Brake Shoes
While you have access to the brakes, take the time to inspect the brake shoes. If they show signs of wear or damage, replace them. The process generally involves removing the springs and clips that hold the shoes in place. Follow the instructions provided with your new brake shoe kit for installation.
Step 7 Install New Brake Drums
After ensuring that everything is clean and dry, carefully install the new brake drum over the brake shoes. Make sure it fits snugly and rotates freely without obstruction. If there were retaining screws, replace them as well.
Step 8 Reattach the Wheel
Replace the wheel onto the hub, and hand-tighten the lug nuts. Once the wheel is back on, carefully lower the vehicle back to the ground using the jack.
Step 9 Tighten Lug Nuts
With the vehicle back on the ground, use the lug wrench to fully tighten the lug nuts in a crisscross pattern to ensure even pressure.
Step 10 Test Drive
Before you hit the road, pump the brake pedal a few times to ensure the system is engaged properly. Take a short test drive to confirm that the brakes are functioning correctly. Listen for any unusual noises and ensure that the car stops smoothly.
In conclusion, changing brake drums is a manageable task with the right tools and patience. Regular maintenance of your vehicle’s braking system not only enhances safety but also improves the overall driving experience. Always consult your vehicle’s manual for specific instructions and torque specifications. If at any point you feel uncomfortable performing these steps, don’t hesitate to seek professional help.
