How to Replace Brake Drums A Step-by-Step Guide
Brake drums play a crucial role in a vehicle's braking system, especially for those equipped with rear drum brakes. Over time, these drums can wear down, become warped, or even crack, leading to decreased performance and potentially dangerous driving conditions. Replacing brake drums is a maintenance task that can be done at home with the right tools and a bit of patience. This guide will walk you through the process step by step.
Tools and Materials Needed
Before starting the replacement, ensure you have the following tools and materials
- Jack and jack stands - Lug wrench - Brake drum puller (if necessary) - Screwdriver - Pliers - New brake drums - New brake shoes (recommended) - Brake cleaner - Lubricant - Shop towels or rags
Step 1 Safety First
Safety should always be your primary concern. Start by parking your vehicle on a level surface and engaging the parking brake. Ensure that you wear safety glasses and gloves to protect yourself during the process.
Step 2 Loosen the Lug Nuts
Using a lug wrench, slightly loosen the lug nuts on the rear wheels of the vehicle. Do not remove them completely at this stage. Loosening them while the vehicle is still on the ground will make it easier to remove them once the vehicle is raised.
Step 3 Lift the Vehicle
Use a jack to lift the rear end of the vehicle. Once it’s elevated, place jack stands under the vehicle for added stability. Always ensure that your vehicle is secure before proceeding.
Step 4 Remove the Wheels
Now that the vehicle is safely lifted, remove the lug nuts completely and take off the rear wheels. This will expose the brake drum.
Step 5 Inspect the Brake Drums
Before removing the drums, inspect them for visible damage or wear. If they are excessively worn or grooved, it’s time to replace them. If you notice any unusual sounds or feel vibrations while driving, it may also indicate the need for new drums.
Step 6 Remove the Brake Drums
If the brake drums are stuck due to rust or dirt buildup, you may need to tap them gently with a hammer to loosen them. Alternatively, a brake drum puller can be used for more stubborn drums. Once they are free, slide them off the wheel hub.
Step 7 Replace the Brake Shoes (Optional but Recommended)
While you have access to the braking system, it's wise to replace the brake shoes as well. Remove the springs and clips holding the old brake shoes in place using pliers and a screwdriver. Install the new brake shoes in the reverse order, ensuring that the components are correctly positioned.
Step 8 Install New Brake Drums
Once the brake shoes are in place, it’s time to install the new brake drums. Slide the new drums onto the wheel hub, ensuring they fit snugly but freely. Rotate them a few times to check for any binding.
Step 9 Reattach the Wheels
With the brake drums securely in place, replace the wheels and hand-tighten the lug nuts. Once all wheels are installed, lower the vehicle back to the ground.
Step 10 Final Tightening
Now that your vehicle is back on the ground, use the lug wrench to tighten the lug nuts in a crisscross pattern to ensure even pressure. Make sure to use the manufacturer’s recommended torque specifications for the best results.
Step 11 Test the Brakes
Before hitting the road, pump the brake pedal a few times to seat the new components. This is crucial, especially if you’ve replaced the brake shoes. Once everything feels normal, take the vehicle for a short test drive at low speeds to ensure that the brakes are functioning properly.
Conclusion
Replacing brake drums is a straightforward task that can enhance your vehicle's safety and performance. By following this guide, you'll not only gain hands-on experience in vehicle maintenance but also save money by avoiding service costs at a repair shop. As always, consult your vehicle’s manual for specific details pertaining to your model, and don’t hesitate to seek professional help if you’re uncertain about any part of the process. Safe driving!
