How to Change Studs on Drum Brakes

Changing studs on drum brakes is an essential skill for car maintenance that can save time and money. Drum brakes often suffer from wear and tear, causing studs to become damaged or stripped. This article will guide you through the process of changing these crucial components to ensure your vehicle performs optimally and safely.

Tools and Materials Needed

Before starting, gather the necessary tools and materials

- New studs - Jack and jack stands - Lug wrench - Brake cleaner - Hammer - Screwdriver - Wire brush or sandpaper - Torque wrench - Safety goggles

Step 1 Safety First

Ensure your safety by wearing protective eyewear and working in a well-lit area. Before beginning any work, park your vehicle on a flat surface and engage the parking brake to prevent any accidental movement.

Step 2 Remove the Wheel

Using the lug wrench, loosen the lug nuts on the wheel with the drum brake you intend to work on. Do not remove them completely yet. Once they are loosened, use the jack to lift the vehicle and stabilize it with jack stands. After securing the vehicle, fully remove the lug nuts and take off the wheel.

Step 3 Remove the Drum

Next, locate the drum brake assembly. If the drum is stuck, it may require a gentle tap with a hammer to loosen it. Be careful not to damage the drum or surrounding components. Once the drum is off, examine the brake shoes, springs, and hardware while ensuring that they are in good condition. If not, consider replacing them as well.

Step 4 Inspect the Studs

Now, you can see the studs clearly. Check each stud for any damage, such as bending or stripping. If you notice that the studs are damaged or worn out, they will need to be replaced.

Step 5 Remove the Damaged Studs

Using your screwdriver and hammer, carefully tap out the damaged studs from the wheel hub. It's important to tap them gently to avoid damaging the surrounding area. If a stud is particularly stubborn, you can use a pair of pliers to pull it out once it’s been loosened.

Step 6 Install New Studs

Take the new studs and insert them into the holes in the wheel hub. Make sure they fit snugly and are aligned properly. To secure them in place, you can place the rotor back onto the hub and tighten down the lug nuts partially to hold the studs steady while you work.

Step 7 Hammer the New Studs

Using a hammer, carefully tap the new studs into position. Be cautious not to apply too much force, as this may damage the threads. The goal is to ensure that the studs sit flush against the wheel hub.

Step 8 Reassemble the Drum and Wheel

Reattach the drum brake assembly and ensure everything is properly seated. Before putting the wheel back on, check that everything is clean and free of debris. You can use brake cleaner and a wire brush or sandpaper for this. Once the drum is secured, carefully place the wheel back on and hand-tighten the lug nuts.

Step 9 Lower the Vehicle

Once the wheel is back on, lower the vehicle using the jack and remove the jack stands. Now that the vehicle is back on the ground, use a torque wrench to tighten the lug nuts to the manufacturer’s specifications.

Step 10 Final Checks

After completing the installation, make sure everything is tightened and secure. Once you’re confident that all components are properly installed, take the vehicle for a short test drive. Pay close attention to any unusual noises or handling issues, which may indicate improper installation.

Conclusion

Changing studs on drum brakes may seem daunting, but with the right tools and approach, it’s an achievable task. Regular maintenance not only enhances your vehicle's performance but also ensures your safety on the road. If you're ever in doubt, don’t hesitate to consult a professional mechanic for assistance.
