How to Replace Rear Brake Drums and Shoes
Brake maintenance is crucial for vehicle safety, and one of the components that often requires replacement is the rear brake drum and shoes. Unlike disc brakes, drum brakes use a different mechanism to create friction and slow down your vehicle. Over time, brake drums can wear out, and shoes may need replacement due to wear, resulting in reduced braking efficiency. This guide will walk you through the steps to replace rear brake drums and shoes effectively.
Tools and Materials Needed
Before starting the replacement process, gather the following tools and materials
- Jack and jack stands - Lug wrench - Brake cleaner - Brake drum puller (if necessary) - Replacement brake drums - New brake shoes - Spring tools (for removal and installation of springs) - Torque wrench - Safety glasses and gloves
Step 1 Prepare the Vehicle
Start by parking your vehicle on a flat, solid surface. Engage the parking brake to prevent any accidental movement. Using the lug wrench, loosen the lug nuts on the rear wheels while the wheels are still on the ground. Do not remove them completely at this stage.
Step 2 Lift the Vehicle
Next, utilize the jack to lift the rear of the vehicle. Ensure it’s stable by placing jack stands underneath the vehicle for safety. Once securely elevated, remove the lug nuts and take off the rear wheels.
Step 3 Inspect the Brake Assembly
With the wheels removed, take a moment to inspect the entire brake assembly. Look for any signs of damage, excessive wear, or corrosion on the brake components. If the brake lines or wheel cylinders appear damaged, consider replacing them as well.
Step 4 Remove the Brake Drum
Now, it’s time to remove the brake drum. Sometimes, the drum may be stuck due to rust or retaining clips. If it doesn’t come off easily, a brake drum puller can be used to facilitate removal. Gently tap around the edge of the drum with a rubber mallet to help loosen it if necessary.
Step 5 Remove Old Brake Shoes
After removing the drum, you’ll see the brake shoes, springs, and other hardware. Take a photo of the assembly for reference during reinstallation. Use spring tools to carefully remove the springs connecting the shoes. Once the springs are off, you can remove the old brake shoes by sliding them out of their slots.
Step 6 Install New Brake Shoes
Take your new brake shoes and slide them into the same position as the old ones. Make sure all the pivot points are aligned properly. Reattach the retaining clips and use the spring tools to secure the springs back into place. The shoes should move freely but not be overly loose.
Step 7 Install New Brake Drums
With the brake shoes installed, you can now put on the new brake drums. Slide the drum over the shoes and push it into place. Ensure it rotates freely without obstruction. If you face any resistance, double-check the shoe alignment and address any issues.
Step 8 Reassemble Everything
Once the drums are installed, put the rear wheels back on and hand-tighten the lug nuts. Lower the vehicle back to the ground and then use a torque wrench to tighten the lug nuts to the manufacturer's specifications. This ensures the wheels are properly secured.
Step 9 Test the Brakes
Before taking your vehicle back on the road, it’s essential to test the brakes. Pump the brake pedal a few times to ensure that the brake shoes are properly seated against the drum. Once the pedal feels firm, take the vehicle for a brief test drive at low speeds to ensure everything is functioning safely.
Conclusion
Replacing rear brake drums and shoes is a vital maintenance task that ensures your vehicle operates safely and efficiently. While it requires some mechanical skill and knowledge, following these steps makes the process manageable for most enthusiasts. Remember to prioritize safety by wearing protective gear and working in a well-lit area. If you are unsure or uncomfortable performing this task, do not hesitate to consult a professional mechanic. Regular brake inspections and timely replacements will keep you safe on the road.
