If you’re experiencing issues with your parking brake or drum brakes, it may be necessary to remove them for inspection or replacement. While this task can seem daunting, it’s actually quite straightforward with the right tools and knowledge. In this comprehensive guide, we’ll walk you through every step of the process, ensuring you tackle this task with confidence.
Tools You’ll Need:
- Jack and jack stands
- Lug wrench
- Socket wrench
- Brake cleaner
- Brake caliper tool
- Parking brake cable pliers
Safety First:
Before beginning any work on your vehicle, always prioritize safety. Engage the parking brake, chock the wheels, and wear appropriate safety gear.
Step 1: Raise and Secure Your Vehicle
Using a jack, carefully lift the vehicle and secure it with jack stands. Ensure the vehicle is stable before proceeding.
Step 2: Remove the Lug Nuts and Wheel
Locate the lug nuts on the wheel and use a lug wrench to loosen them. Once loose, remove the lug nuts and carefully lift the wheel off the hub.
Step 3: Disconnect the Brake Line
Using a brake caliper tool, gently squeeze the brake caliper pistons back into the caliper. Once the pistons are retracted, disconnect the brake line from the caliper.
Step 4: Remove the Brake Caliper
Remove the bolts holding the brake caliper in place. Carefully lift the caliper up and away from the rotor. Support the caliper with a bungee cord or wire to prevent damage to the brake line.
Step 5: Remove the Parking Brake Cable
Locate the parking brake cable attached to the backing plate. Use parking brake cable pliers to disconnect the cable from the lever.
Step 6: Remove the Drum Brake Assembly
Slide the drum brake assembly off the axle. Be careful not to damage the wheel bearings or axle seal.
Step 7: Inspect and Replace Components
Once the drum brake assembly is removed, inspect the components for wear or damage. If necessary, replace worn or damaged parts such as brake shoes, wheel cylinders, or springs.
Step 8: Reassemble the Drum Brake Assembly
Assemble the drum brake components in the reverse order of removal. Ensure all components are properly seated and tightened.
Step 9: Reinstall the Parking Brake Cable
Connect the parking brake cable to the lever on the backing plate. Adjust the cable tension as per the manufacturer’s specifications.
Step 10: Reinstall the Brake Caliper
Position the brake caliper over the rotor and secure it with the bolts. Tighten the bolts to the specified torque.
Step 11: Reconnect the Brake Line
Connect the brake line to the caliper and tighten the fitting. Bleed the brake system to remove any air from the lines.
Step 12: Reinstall the Wheel and Lug Nuts
Place the wheel back on the hub and tighten the lug nuts by hand. Use a lug wrench to further tighten the lug nuts to the specified torque.
Step 13: Lower the Vehicle
Carefully lower the vehicle from the jack stands. Remove the jack and wheel chocks.
Tips for Success:
- Use penetrating oil to loosen rusty bolts or nuts.
- Inspect the brake shoes for wear or glazing.
- Clean all components thoroughly with brake cleaner before reassembly.
- Refer to your vehicle’s repair manual for specific instructions and torque specifications.
