How to Change Brake Drums A Step-by-Step Guide

Changing brake drums is an essential skill for any car owner who wants to save money on repairs and take control of their vehicle's maintenance. Brake drums serve a critical function in the vehicle's braking system, providing the necessary friction to slow down or stop the vehicle. While the process can seem daunting, with the right tools and a little patience, you can change your brake drums effectively. In this guide, we'll walk you through the steps necessary to accomplish this task.

Tools and Materials Needed

Before you begin, gather the following tools and materials

1. Safety Gear Safety glasses and gloves. 2. Jack and Jack Stands To safely elevate the vehicle. 3. Lug Wrench To remove the wheel nuts. 4. Brake Drum Puller If the drum is stuck. 5. Socket Set For removing drum assembly parts. 6. Brake Cleaner To clean the drum and components. 7. New Brake Drums Ensure they are the correct size for your vehicle. 8. New Brake Shoes It’s often a good idea to replace them while you’re at it.

Step 1 Prepare the Vehicle

First, park your vehicle on a flat surface and engage the parking brake. Make sure the engine is turned off and the keys are removed. If you are working on the rear brakes, the process will be similar for the front brakes, but check your manual for specifics.

Step 2 Loosen the Wheel Nuts

Using a lug wrench, loosen the wheel nuts while the vehicle is still on the ground. Turn the nuts counterclockwise, but do not remove them completely yet. Simply breaking the torque will make it easier to remove them once the vehicle is lifted.

Step 3 Elevate the Vehicle

Using a jack, lift the vehicle until the wheel is off the ground. Secure it with jack stands for stability. Never rely solely on the jack to support the vehicle.

Step 4 Remove the Wheel

Now that the vehicle is securely elevated, fully remove the loosened lug nuts and take off the wheel. Set it aside in a safe place.

Before proceeding to remove the drum, inspect the brake assembly for wear. You want to check the brake shoes, springs, and other components for any signs of damage. It’s often a good idea to replace the brake shoes when changing the drum to ensure optimal performance.

Step 6 Remove the Brake Drum

At this point, try to remove the brake drum. If it comes off easily, great! If it feels stuck, you may need to use a brake drum puller to loosen it. Attach the puller to the drum and turn the screw to apply pressure until the drum releases. Be cautious during this step; ensure that you’re supporting the drum as it comes off to prevent it from falling.

Step 7 Clean the Brake Assembly

Once the drum is off, take the time to clean the brake assembly using brake cleaner. This will help eliminate dust and debris that could affect braking performance. Make sure you clean any other components that need attention.

Step 8 Install New Brake Drums

Now it’s time to install the new brake drums. Place the new drum onto the hub, making sure it’s seated properly. If you are replacing brake shoes, follow the manufacturer’s instructions for installation before placing the drum.

Step 9 Reassemble

Reattach any components you removed, and replace the wheel onto the hub. Align the holes and start threading on the lug nuts by hand to ensure they fit properly.

Step 10 Lower the Vehicle

Once everything is back in place, lower the vehicle off the jack stands, and back onto the ground. Once it’s secure, use the lug wrench to tighten the lug nuts in a crisscross pattern to ensure they are evenly tightened.

Conclusion

Changing brake drums can seem like a complicated task, but by following these straightforward steps and working methodically, you can perform this maintenance yourself. Always consult your vehicle manual for specific instructions related to your car model and ensure that you adhere to all safety precautions. Regular maintenance of your braking system is crucial for your vehicle's safety, and being proactive about changing brake drums can save you from future headaches on the road. Happy driving!
