Steps to Replace and Adjust Brake Drums for Optimal Vehicle Performance

How to Change Brake Drums A Step-by-Step Guide


Changing brake drums is an essential skill for DIY enthusiasts and car owners alike. Brake drums are vital components of a vehicle’s braking system, and over time, they can wear down, affecting braking performance. This guide will walk you through the basic steps to change brake drums safely and efficiently.


Tools and Materials Needed


Before beginning the process, it’s crucial to gather all the necessary tools and materials


1. Tools - Socket set - Wrench set - Screwdrivers (flat-head and Phillips) - Brake drum puller - Torque wrench - Pliers


2. Materials - New brake drums - New brake shoes (it’s often recommended to replace both simultaneously) - Brake cleaner - Brake grease - Safety equipment (gloves, safety glasses)


Step 1 Prepare Your Vehicle


1. Safety First Ensure the vehicle is parked on a flat surface. Engage the parking brake to prevent any movement. 2. Loosen Lug Nuts Using a lug wrench, slightly loosen the lug nuts on the wheel whose brake drum you’re replacing without removing them completely.


3. Jack Up the Vehicle Use a jack to lift the vehicle, then secure it with jack stands for safety. Remove the wheel completely to access the brake drum.


Step 2 Remove the Brake Drum


1. Inspect the Drum Look for any retaining screws that hold the drum in place and remove them if present.


2. Use a Brake Drum Puller If the drum is stuck due to rust or wear, utilize a brake drum puller. Attach it securely, and turn the handle to apply pressure until the drum loosens.


3. Remove the Drum Carefully slide the drum off the hub. If it does not come off easily, check for additional screws or clips that may be holding it in place.

Step 3 Replace Brake Shoes


1. Remove Old Brake Shoes Take note of how the current shoes are installed. Remove any springs and clips that hold the shoes in position.


2. Install New Brake Shoes Position the new brake shoes in place, making sure they align properly with the braking mechanism. Reattach the springs and clips securely.


Step 4 Install New Brake Drum


1. Clean the Area Before installing the new drum, clean the hub and ensure there is no dirt or debris.


2. Apply Brake Grease Lightly grease the backing plate to facilitate smooth movement of the brake shoes.


3. Install the New Drum Slide the new brake drum onto the hub, ensuring it fits snugly over the new brake shoes. Replace any retaining screws you removed earlier.


Step 5 Reassemble and Test


1. Reattach the Wheel Place the wheel back onto the hub, tighten the lug nuts by hand, and lower the vehicle from the jack stands.


2. Tighten Lug Nuts Once the vehicle is back on the ground, use a torque wrench to tighten the lug nuts to the manufacturer’s specifications.


3. Test the Brakes Before hitting the road, pump the brake pedal a few times to seat the new shoes against the drum. Finally, take a short test drive to ensure everything is functioning correctly.


Changing brake drums is a manageable task that can save you time and money. By following these steps, you can maintain your vehicle's braking system, ensuring safety for you and your passengers. Always consult your vehicle’s manual for specific instructions and torque specifications.
