Removing the Rear Brake Drum A Step-by-Step Guide
Maintaining your vehicle's braking system is crucial for ensuring safety on the road. One of the key components in the drum brake system is the rear brake drum itself. Over time, brake drums may wear out or become contaminated with brake dust or moisture, necessitating their removal and possible replacement. This article outlines the steps involved in removing a rear brake drum, along with some tips and precautions.
Tools and Materials Required
Before starting, gather the necessary tools and materials - Jack and jack stands - Lug wrench - Screwdriver (flat head or Phillips depending on the drum) - Brake cleaner - Gloves and safety goggles - New brake shoes (if necessary) - Torque wrench
Step-by-Step Removal Process
1. Preparation and Safety Measures Begin by ensuring your vehicle is parked on a flat, stable surface. Engage the parking brake to prevent any movement. Wear gloves and safety goggles to protect yourself from dust and debris.
2. Loosening the Lug Nuts Use the lug wrench to slightly loosen the lug nuts on the rear wheel before lifting the vehicle. This step is crucial as it prevents the wheel from spinning while you’re loosening the nuts later.
3. Lifting the Vehicle Jack up the rear of the vehicle using the designated lift points and securely place jack stands beneath the vehicle for added safety. Ensure the vehicle is stable before proceeding.
4. Removing the Wheel Once the vehicle is securely lifted, fully remove the loosened lug nuts and remove the wheel. This will expose the rear brake drum.
5. Inspecting the Brake Drum Before removal, take a moment to inspect the brake drum for signs of damage or wear. If the drum surface is scored or excessively corroded, replacement might be necessary.
6. Removing the Brake Drum The next step involves removing the brake drum. In some cases, the drum might be secured with screws; if so, use a screwdriver to remove them. If the brake drum is stuck due to rust or debris, gently tap around the drum’s edge with a hammer to loosen it. Be careful not to damage any components in the process. Once loosened, pull the drum straight off the hub.
7. Inspecting and Replacing Brake Parts After removing the drum, inspect the brake shoes, springs, and other internal components for wear. If the lining on the brake shoes is worn down or if you notice any other issues, replace the shoes before reassembling the drum.
8. Cleaning the Components Use brake cleaner to thoroughly clean the drum, shoes, and backing plate. This step helps to eliminate contaminants and ensures optimal performance.
9. Reassembling If everything is in order, carefully slide the drum back onto the hub. Reattach any screws if applicable. Reinstall the wheel, tightening the lug nuts by hand before lowering the vehicle.
10. Lowering the Vehicle Remove the jack stands and lower the vehicle back to the ground. Once it’s on the ground, use the torque wrench to tighten the lug nuts to the manufacturer’s recommended specifications.
11. Testing Before hitting the road, pump the brake pedal a few times to reset the brake shoes against the drum. Test the brakes at low speed to ensure everything is functioning properly.
Conclusion
Removing the rear brake drum may seem daunting at first, but with the right tools and a methodical approach, you can successfully complete the task. Regular maintenance of your vehicle’s braking system helps ensure your safety on the road. Should you encounter any complexities, don’t hesitate to consult a professional mechanic for assistance. Remember, a well-maintained braking system is vital for the safety of you and your passengers.
