How to Replace Drum Brake Pads

When it comes to maintaining your vehicle, ensuring that your brake system remains in optimal condition is crucial for your safety and the safety of others on the road. Drum brake pads, although not as common as disc brakes in modern vehicles, are still utilized in many cars, especially in the rear brakes of older models. Replacing drum brake pads can seem daunting, but with the right tools and guidance, you can tackle the job yourself. This article will guide you through the process of replacing your drum brake pads in a few straightforward steps.

Tools and Materials Needed

Before you begin, gather the necessary tools and materials - A jack and jack stands - A lug wrench - Brake drum puller (if necessary) - New brake pads - Brake cleaner - C-clamp or brake expander tool - Torque wrench (optional) - Gloves and safety glasses

Step 1 Safety First

Before you start working on your car, ensure it’s parked on a flat surface, and engage the parking brake. Wear safety glasses and gloves to protect yourself from debris and sharp objects.

Step 2 Remove the Wheel

Using a lug wrench, loosen the lug nuts on the wheel where you will be replacing the drum brake pads. After loosening them, use a jack to lift the vehicle and secure it with jack stands for safety. Once the vehicle is secure, remove the lug nuts completely and take off the wheel.

Step 3 Access the Brake Drum

Inspect the brake assembly and locate the brake drum. If the drum is stuck, you may need to use a brake drum puller to safely remove it. Once removed, you’ll see the brake shoes and other components inside the assembly.

Step 4 Remove the Old Brake Shoes

Take note of how the old brake shoes are positioned before removing them, as you will install the new ones in the same manner. Remove the retaining springs and any hardware that holds the brake shoes in place. Carefully slide out the old brake shoes from the backing plate.

Step 5 Prepare for Installation

Before installing the new brake shoes, clean the brake assembly with brake cleaner to remove any dust or debris. Inspect the hardware for wear and replace if necessary. If the brake cylinder is leaking or damaged, it should be repaired or replaced as well.

Step 6 Install New Brake Shoes

Take the new brake shoes and position them in the same layout as the old ones. Start by sliding the shoes into place on the backing plate and then reattach the retaining springs. When reassembling, ensure that any clips, adjusters, and the spring tension are appropriate to ensure the shoes fit snugly.

Step 7 Reinstall the Brake Drum

Once the new brake shoes are installed, carefully slide the brake drum back onto the wheel hub. Ensure that it rotates freely without rubbing against the shoes. If you encounter resistance, check the installation and adjust the shoes accordingly.

Step 8 Reattach the Wheel

With the brake drum in place, it’s time to reinstall the wheel. Place the wheel back onto the hub, hand-tighten the lug nuts, and then lower the vehicle from the jack stands. Once the vehicle is on the ground, use the lug wrench to tighten the lug nuts securely in a star-pattern to ensure even tightening.

Step 9 Test the Brakes

Before driving the vehicle, depress the brake pedal several times to seat the new shoes against the drum properly. This step is crucial as it ensures the brake system is ready for use. Once satisfied, take your vehicle for a short test drive at a low speed to ensure the brakes are functioning correctly.

Conclusion

Replacing drum brake pads may seem like a challenging task, but with the right approach and tools, it can be done efficiently. Regular maintenance of your brake system not only prolongs the life of the components but also enhances the safety of your vehicle. Always refer to your vehicle’s manual for specific instructions and specifications. If you’re ever in doubt, consult with a professional mechanic to ensure the job is done correctly.
