How to Get a Stuck Rear Brake Drum Off
Removing a stuck rear brake drum can be a challenging task, especially if you’re not familiar with the tools and techniques involved. Brake drums can become seized on the hub due to corrosion, dirt, or the brake shoes expanding against the drum surface. However, with the right approach, you can successfully remove a stuck brake drum. This guide will provide you with a step-by-step process to help you tackle this task safely and effectively.
Tools and Materials Needed
Before you start, gather the following tools and materials
- Safety goggles and gloves - Jack and jack stands - Lug wrench - Brake drum puller (if available) - Hammer - Penetrating oil (such as WD-40 or PB Blaster) - Flathead screwdriver - Pliers - Cleaning brush
Step 1 Safety First
Before you begin any work, ensure that you prioritize safety. Put on safety goggles and gloves to protect yourself from any debris that may fly when you are working on the brake drum. Make sure your vehicle is parked on a flat surface, and engage the parking brake.
Step 2 Lift the Vehicle
Using a jack, lift the rear of the vehicle and secure it on jack stands. This will give you proper access to the wheels and brake system. Make sure the vehicle is stable before you proceed.
Step 3 Remove the Wheel
Using a lug wrench, remove the lug nuts and take off the rear wheel
. This will expose the brake drum and allow you to access it more easily.Step 4 Inspect the Brake Drum
Inspect the brake drum for any visible damage or excessive rust. If the brake shoes are worn against the drum, this can cause them to grip tightly, making removal more difficult.
Step 5 Apply Penetrating Oil
If the drum appears stuck, apply penetrating oil around the edges where the drum meets the hub. Allow the oil to soak in for about 10-15 minutes. This will help to loosen any rust or debris that may be causing the drum to stick.
Step 6 Use a Hammer
Gently tap around the drum with a hammer to help break any corrosion. Use a rubber mallet if you have one, as it will be less likely to damage the drum. If you don’t have a rubber mallet, cover the drum with a piece of wood before hitting it to reduce the risk of damaging the surface. Be careful not to hit too hard; the goal is to break the seal created by rust, not to dent the drum.
Step 7 Use a Brake Drum Puller
If the drum still won’t budge, consider using a brake drum puller. This tool can be attached to the drum and will apply even pressure to help pull it away from the hub. Follow the instructions provided with the tool for proper usage, ensuring that you have a secure fit before applying force.
Step 8 Release the Adjuster
If the brake shoes are still snug against the drum, you may need to release the brake adjuster. Locate the adjustment slot on the backing plate and use a flathead screwdriver to turn the adjuster in the direction that will retract the shoes. This can provide additional space for the drum to come off more easily.
Step 9 Pull the Drum Off
With the above steps completed, try pulling the drum off again. Rock it back and forth gently while pulling. If it still resists, repeat the process of applying penetrating oil, hammering, and using the puller until it loosens.
Step 10 Clean and Inspect
Once you have successfully removed the drum, clean the hub and inspect both the drum and brake shoes for wear and damage. Replace any worn components as necessary.
Conclusion
Removing a stuck rear brake drum can take patience and the right techniques. By using penetrating oil, applying gentle force, and utilizing a brake drum puller when necessary, you can successfully free the drum. Always remember to follow safety precautions and inspect your brake components for any signs of wear or damage before reassembly. Happy repairing!
