How to Replace Drum Brakes A Step-by-Step Guide

Replacing drum brakes can be a daunting task for many car owners, but with the right tools and a bit of patience, it can be accomplished in a few hours. Drum brakes are commonly found on the rear wheels of many vehicles, and over time, they can wear out, leading to decreased braking efficiency. In this guide, we will walk you through the steps to replace drum brakes safely and effectively.

Tools and Materials Needed

Before you start, gather the following tools and materials

- Jack and jack stands - Lug wrench - Brake cleaner - Screwdrivers (flathead and Phillips) - Pliers - Brake drum puller (optional, if the drum is stuck) - New brake shoes - Brake hardware kit (springs, clips, etc.) - Torque wrench

Step 1 Prepare the Vehicle

1. Safety First Park the vehicle on a flat, stable surface and turn off the engine. Ensure the parking brake is engaged. 2. Loosen Lug Nuts Using a lug wrench, slightly loosen the lug nuts on the rear wheels while the vehicle is still on the ground.

3. Jack Up the Vehicle Use a jack to raise the rear of the vehicle and secure it with jack stands. Never rely solely on the jack for support.

Step 2 Remove the Wheel

1. Remove Lug Nuts Finish removing the lug nuts and take off the wheel. Set it aside in a safe place.

Step 3 Access the Drum Brakes

1. Inspect the Drum Check for any visible damage on the brake drum. If it appears scored or excessively worn, consider replacing it as well.

2. Remove the Brake Drum If the drum doesn’t slide off easily, you may need a brake drum puller to remove it without damaging other components.

Step 4 Disassemble the Brake Assembly

1. Take Pictures Before disassembling, take photos of the existing setup. This will be a helpful reference when installing the new components.

2. Remove the Old Brake Shoes Start by removing any retaining clips, springs, and adjusters. Use pliers and screwdrivers as needed to carefully detach these parts.

3. Inspect Components Examine the wheel cylinder and other brake hardware for wear or leaks. If any parts are damaged, replace them accordingly.

Step 5 Install New Brake Shoes

1. Prepare New Parts If your new brake shoes came with a hardware kit, install the new springs and clips according to the pictures you took earlier.

2. Position New Brake Shoes Place the new brake shoes into the drum assembly, ensuring that the adjusting lever and springs are positioned correctly.

3. Reconnect the Wheel Cylinder Carefully ensure the wheel cylinder is back in place and connected to the shoes.

Step 6 Reassemble and Test

1. Reinstall the Brake Drum Slide the brake drum back into place. Ensure it rotates freely without excess friction.

2. Replace the Wheel Put the wheel back on, hand-tighten the lug nuts, and lower the vehicle back to the ground.

3. Tighten Lug Nuts Use a torque wrench to securely tighten the lug nuts to the manufacturer’s specifications.

Step 7 Test the Brakes

Before taking your vehicle on the road, pump the brake pedal a few times to seat the brake shoes against the drum. This step ensures that your brakes are functioning properly.

Conclusion

Replacing drum brakes is a straightforward process that can save you money on repair costs. With careful attention to detail and a commitment to safety, you can effectively maintain your vehicle's braking system. Always consult your vehicle’s owner manual for specific instructions and torque specifications, and remember that if you feel unsure at any point, it’s wise to seek professional assistance. Happy motoring!
