How Do I Change Drum Brakes A Step-by-Step Guide

Changing drum brakes is an essential skill for any DIY mechanic or an economical car owner. Understanding how to replace drum brakes can save you money on labor costs and help ensure your vehicle remains safe and reliable. In this guide, we will walk you through the process of changing drum brakes step by step.

Tools and Materials Needed

Before you begin, gather the following tools and materials

- Jack and jack stands - Lug wrench - Brake cleaner - Screwdriver (flathead and Phillips) - Pliers - Drum brake replacement kit (brake shoes, springs, and any necessary hardware) - Torque wrench - Gloves and eye protection

Step 1 Preparation

Start by ensuring your vehicle is parked on a flat, level surface. Engage the parking brake and wear appropriate safety gear. Before working on the car, it’s a good idea to disconnect the battery to eliminate any electrical hazards.

Step 2 Loosen the Lug Nuts

Using a lug wrench, slightly loosen the lug nuts on the wheel you will be working on while the vehicle is still on the ground. You don’t have to remove them completely at this stage.

Step 3 Jack Up the Vehicle

Using a jack, raise the vehicle and secure it with jack stands for safety. Ensure the vehicle is stable before attempting to remove the wheel.

Step 4 Remove the Wheel

Now, completely remove the lug nuts and take off the wheel. This exposes the drum brake assembly.

Step 5 Remove the Brake Drum

Inspect the brake drum for any retaining screws that may be holding it in place. If there are screws, remove them with a screwdriver. If the brake drum is stuck, gently tap it with a hammer to free it from the hub. Make sure not to damage the drum in the process.

Step 6 Inspect the Old Brake Shoes

Once you have removed the drum, inspect the old brake shoes for wear. If they appear worn down, it's time to replace them. Take note of how the old shoes are positioned and the order of any springs and hardware, as this will help you in the reassembly process.

Step 7 Remove the Old Brake Shoes

Use pliers to unhook the springs and disconnect the brake shoes from their mounting points. Carefully remove the old brake shoes and any associated hardware.

Step 8 Clean the Brake Components

Before installing the new brake shoes, clean the inside of the drum and surrounding components using brake cleaner. This step ensures that dust and debris do not interfere with the braking process.

Step 9 Install the New Brake Shoes

Position the new brake shoes into the mounting points. reattach springs and any other hardware to secure the shoes in place. Refer to the notes you took during disassembly to ensure everything is being put back in the correct order.

Step 10 Reattach the Brake Drum

Once the new shoes are installed, carefully place the brake drum back onto the wheel hub. Ensure it spins freely and doesn’t rub against the new shoes. If it does, you may need to adjust the shoes with the adjustment wheel, which is typically located at the bottom of the assembly.

Step 11 Reinstall the Wheel

Place the wheel back on the hub and hand-tighten the lug nuts. Lower the vehicle back to the ground using the jack and remove the jack stands.

Step 12 Tighten the Lug Nuts

With the vehicle back on the ground, use a torque wrench to tighten the lug nuts to the manufacturer’s specified torque rating. This ensures the wheel is securely fastened.

Step 13 Test the Brakes

Before driving, pump the brake pedal several times to seat the new shoes against the drum. This action will also help to ensure proper brake pedal feel and function. Take your vehicle for a short test drive in a safe area to verify that the brakes are functioning properly.

Conclusion

Changing drum brakes may seem challenging initially, but by following these steps and taking your time, you can successfully replace them yourself. Not only can this save you money, but it also gives you a deeper understanding of your vehicle's braking system. Always prioritize safety, and do not hesitate to consult your vehicle's manual for specific recommendations regarding your make and model. Happy wrenching!
