How to Replace Drum Brakes on Any Vehicle

Introduction

This tutorial will guide you through the process of replacing drum brakes on any vehicle. Understanding how drum brakes work and the steps involved in replacing them can help ensure your vehicle's braking system functions effectively. Whether you're a seasoned DIYer or tackling this for the first time, this guide will provide you with the necessary steps and tips.

Step 1: Prepare Your Vehicle

• Loosen the Lug Nuts: Before lifting the vehicle, slightly loosen the lug nuts while it's still on the ground. This makes it easier to remove the wheel later.
• Lift and Support the Vehicle: Use a jack to lift the vehicle and secure it with jack stands on level ground for safety.

Step 2: Remove the Brake Drum

• Check for Rust: Brake drums can be difficult to remove due to rust buildup from the brake shoes.
• Use a Hammer: Gently tap the drum between the wheel studs with a hammer to help free it from rust.
• Adjust the Brake Shoes: Locate the adjustment hole, usually found on the drum or backing plate. Use a flat screwdriver to adjust the brake shoes inward, which will help free the drum.
• Remove the Drum: Once freed, pull the drum straight off the hub.

Step 3: Inspect Brake Components

• Check Drum Specifications: Look for the maximum drum diameter marking. If the drum exceeds this size, it must be replaced.
• Inspect Brake Shoes: Check the condition of the brake shoes. If they are worn, they will need replacement.
• Examine the Wheel Cylinder: Ensure the wheel cylinder is not corroded. If it shows signs of wear or damage, consider replacing it.

Step 4: Replace Brake Shoes

• Remove Springs: Use needle-nose pliers to carefully remove the springs connecting the shoes to the backing plate.
• Take Photos: Document the arrangement of parts with photos to aid reassembly.
• Take Off the Shoes: Once the springs are removed, slide the shoes off the wheel cylinder and backing plate.

Step 5: Clean and Lubricate Components

• Clean the Adjuster: Remove the adjuster, clean it, and apply anti-seize grease to ensure it operates smoothly.
• Check Parking Brake Mechanism: Ensure the lever for the parking brake pivots freely.

Step 6: Install New Brake Shoes

• Position New Shoes: Slide the new brake shoes onto the wheel cylinder and backing plate.
• Reattach Springs: Reinstall the springs using the same method as removal, ensuring they are securely fastened.

Step 7: Adjust Brake Shoes

• Set the Adjuster: Use the adjuster to position the shoes so they are close to the drum without dragging.
• Access Panel: If available, use the access panel to adjust the shoes after the drum is back on.

Step 8: Reinstall the Brake Drum

• Slide the Drum Back On: Carefully place the drum over the newly installed brake shoes.
• Final Adjustments: If necessary, use the access panel to make final adjustments to the shoe position.
