Removing Rear Drum Brakes A Step-by-Step Guide
Removing rear drum brakes might seem like a daunting task, but with the right tools and a bit of know-how, it can be accomplished by anyone with basic mechanical skills. Drum brakes are commonly used in older vehicles and some modern cars due to their effective braking power, especially for rear wheels. Whether you're looking to replace worn-out components, upgrade to disc brakes, or perform routine maintenance, this guide will take you through the steps involved in safely removing rear drum brakes.
Tools and Materials Needed
Before you begin, ensure you have the following tools and materials
- Jack and jack stands - Lug wrench - Brake drum puller (if necessary) - Screwdrivers (flathead and Phillips) - Socket set and ratchet - Pliers - Brake cleaner - Shop rags - New brake components (if you're replacing them) - Safety glasses and gloves
Step 1 Prepare the Vehicle
Start by parking your vehicle on a flat, stable surface. Engage the parking brake, and if you're removing the rear drum brakes, make sure to block the front wheels to prevent the vehicle from rolling. Next, loosen the lug nuts on the rear wheels slightly—do not remove them yet.
Step 2 Lift the Vehicle
Using the jack, lift the rear of the vehicle and secure it with jack stands. Ensure the vehicle is stable before proceeding. Once it's secure, remove the lug nuts and take off the rear wheels to access the drum brakes.
Step 3 Inspect the Brake Assembly
With the wheels removed, take a moment to inspect the brake assembly. Look for signs of wear or damage, such as cracked or worn brake shoes, leaking wheel cylinders, or damaged springs. This will help you understand what needs to be replaced.
Step 4 Removing the Brake Drum
To remove the brake drum, you may need to disengage the adjusting mechanism. Locate the access hole on the back of the drum, usually covered by a rubber plug or a small cover. This hole is used to adjust the brake shoes. Use a screwdriver to turn the adjuster, retracting the shoes inward to release the tension on the drum.
If the drum is stuck due to rust or buildup, a brake drum puller might be necessary. Attach the puller to the drum and turn the center screw to remove the drum if it doesn't come off easily. Be cautious and ensure the puller is adequately secured to avoid any accidents.
Step 5 Disconnecting the Brake Components
Once the drum is removed, you will see the brake shoes and other components. Document the configuration of the brake assembly by taking pictures, as this will help during reassembly. Carefully disconnect the springs and retaining clips using pliers, and remove the brake shoes from the backing plate.
Take special care with the hardware—if you’re reusing it, keep everything organized. If you plan to replace the brake shoes, ensure you’ve purchased the correct replacement parts.
Step 6 Clean and Inspect
Before installing new components, take this time to clean the backing plate and other components. Use brake cleaner to remove dust and grime. Inspect the wheel cylinder for leaks and ensure it is functioning correctly. If necessary, replace any damaged parts.
Step 7 Installing New Brake Components
If you're replacing the brake shoes, install them in the reverse order of removal. Start with the lower spring, securing the shoes to the backing plate, and then attach the upper springs and any retaining clips. Ensure everything is tight and secure, following the original orientation you documented.
Step 8 Reattach the Drum and Wheels
Once the new shoes are installed, reattach the brake drum. Ensure it rotates freely with no binding. Next, reinstall the wheels, hand-tightening the lug nuts before lowering the vehicle back to the ground.
Conclusion
Removing rear drum brakes can be a straightforward process if carried out with care and attention to detail. Always ensure you follow safety procedures and consult your vehicle’s service manual for any specific instructions. If at any point you feel unsure, don’t hesitate to seek professional help. Proper braking is crucial for vehicle safety, and maintaining your brakes should always be a priority. Enjoy the satisfaction of knowing you’ve completed the task yourself!
