How to Change Drum Brake Pads
Changing drum brake pads is a crucial skill for any car owner or enthusiast, as it ensures your vehicle's braking system remains efficient and safe. Unlike disc brakes, which are more common in modern vehicles, drum brakes operate differently and require a specific process for replacement. This guide will walk you through the steps necessary to change drum brake pads effectively.
Tools and Materials
Before you begin, gather the following tools and materials
- jack and jack stands - lug wrench - brake drum puller (if needed) - socket set - screwdriver - new brake pads - brake cleaner - safety goggles and gloves
Step 1 Prepare the Vehicle
Ensure your vehicle is parked on a flat surface and engage the parking brake. Begin by loosening the lug nuts on the tire covering the drum brake. Do not remove them completely yet. Next, use a jack to lift the vehicle and secure it with jack stands. Remove the wheel entirely.
Step 2 Inspect the Brake Assembly
With the wheel removed, inspect the brake assembly. Drum brakes consist of several parts, including the brake drum, brake shoes, springs, and adjusters. Before you proceed, check for any excessive wear or damage to these components.
Step 3 Remove the Brake Drum
If the drum does not come off easily, you may need to use a brake drum puller. Attach the puller according to the manufacturer's instructions and carefully extract the drum from the wheel hub. Once removed, inspect the inner surface for grooves or scoring, which may necessitate a drum replacement or resurfacing.
Step 4 Remove Old Brake Shoes
With the drum off, you can now access the brake shoes. Carefully unhook the springs and remove the retaining clips holding the brake shoes in place. Keep track of how everything is assembled, which will help during reinstallation. Take note of the orientation of the shoes and any other components to ensure proper rebuilding.
Step 5 Install New Brake Shoes
Begin by placing the new brake shoes in the same configuration as the old ones. Reattach the retaining clips and springs. It is essential to ensure all components are securely connected and in the correct position. Caution is advised here, as improperly installed brake shoes can lead to poor brake performance or even failure.
Step 6 Reinstall the Brake Drum
Once the new shoes are installed, gently slide the brake drum back over the shoes. Make sure it rotates freely; if it’s too tight, you may need to adjust the brake shoes using the adjuster wheel. This is typically located at the bottom of the brake assembly and can be adjusted until you have a snug fit that allows for smooth rotation of the drum.
Step 7 Reattach the Wheel
With everything reassembled, replace the wheel and hand-tighten the lug nuts. Lower the vehicle back to the ground and then fully tighten the lug nuts in a crisscross pattern to ensure even pressure.
Step 8 Test the Brakes
Before hitting the road, it’s essential to test the brakes. Pump the brake pedal a few times to adjust the shoes to the drum and ensure they are making proper contact. Check for any unusual noises or issues when you first drive, as this may indicate an improper installation.
Conclusion
Changing drum brake pads might seem daunting, but with the right tools and a little patience, it can be a rewarding DIY task. Regular maintenance of your braking system not only enhances your vehicle's performance but also ensures your safety on the road. Always remember to consult your vehicle’s service manual for specific instructions and specifications related to your car's braking system.
