Replacing Brake Shoes on Drum Brakes A Step-by-Step Guide
Brake systems are crucial for the safe operation of any vehicle. Among the various braking systems, drum brakes are widely used, especially in older cars and some modern vehicles. One essential component of drum brakes is the brake shoes, which play a vital role in creating friction to stop the vehicle. Over time, these shoes can wear out and need replacement. Here’s a comprehensive guide on how to replace brake shoes effectively.
Tools and Materials Needed
Before starting the job, gather the necessary tools and materials
1. Jack and jack stands 2. Lug wrench 3. Screwdrivers (flathead and Phillips) 4. Brake shoe replacement kit 5. Brake cleaner 6. C-clamp or brake spring tool 7. Safety glasses and gloves
Preparation
1. Ensure Safety First Park the vehicle on a flat surface, set the parking brake, and wear safety glasses and gloves to protect yourself from debris. 2. Loosen the Lug Nuts Using a lug wrench, slightly loosen the lug nuts on the wheel where you plan to replace the brake shoes. Do not remove them yet.
3. Lift the Vehicle Use a jack to lift the vehicle and secure it with jack stands. Make sure the vehicle is stable before proceeding.
4. Remove the Wheel Fully remove the lug nuts and take off the wheel to expose the drum brake assembly.
Removing the Drum
1. Inspect the Drum Check the condition of the brake drum. If it’s worn out, consider replacing it as well.
2. Remove the Drum Gently tap the drum with a hammer to loosen it. If it’s stuck, use brake cleaner to help break the grip. Once loose, pull the drum off the wheel hub.
Taking Out the Old Brake Shoes
1. Identify the Shoe Assembly Examine how the brake shoes are installed. Take note of the arrangement and the placement of springs and retaining clips.
2. Disconnect Springs Using a C-clamp or brake spring tool, carefully remove the tension springs that hold the shoes in place. Be cautious, as these springs can snap back.
3. Remove the Shoes Once the springs are detached, slowly take out the old brake shoes. Be aware of any retaining clips and any wiring (if applicable) that may need to be disconnected.
Installing New Brake Shoes
1. Preparation Clean the brake assembly with brake cleaner to remove dust and debris.
2. Install New Shoes Place the new brake shoes into the same position as the old ones. Ensure they align properly with the backing plate.
3. Reconnect Springs Reattach the springs and ensure everything is secure. It’s crucial that the springs have the correct tension for proper brake function.
Reassemble and Test
1. Reinstall the Drum Carefully place the brake drum back over the shoes, ensuring it’s seated correctly.
2. Replace the Wheel Put the wheel back on and hand-tighten the lug nuts. Lower the vehicle from the jack stands and tighten the lug nuts fully in a crisscross pattern.
3. Test the Brakes Before driving, pump the brake pedal a few times to ensure the shoes are properly seated. Execute a cautious test drive to check for proper brake function.
Conclusion
Replacing brake shoes on drum brakes is a manageable task for those willing to learn and invest time. By following the steps outlined above and prioritizing safety, vehicle owners can maintain their drum brake systems effectively. Regular brake inspections can greatly enhance vehicle safety and performance, ensuring a smooth ride for all drivers.
