Is It Hard to Change Drum Brakes?

When it comes to vehicle maintenance, one of the key components that demand attention is the braking system. Drum brakes, in particular, are still common on many vehicles, especially older models and some economical ones. Understanding the intricacies involved in changing drum brakes can not only save you money but also enhance your troubleshooting skills. So, is it hard to change drum brakes? Let’s delve into it.

Understanding Drum Brakes

Before tackling the question, it's essential to understand how drum brakes work. Unlike disc brakes that use calipers and rotors, drum brakes rely on shoes that press against the inner surface of a drum to create friction and, consequently, stopping power. This design is effective but can also be more complicated to service than disc brakes.

Tools Required

Changing drum brakes requires specific tools. You will need a jack and jack stands, a tire iron, a socket set, a brake spring tool, and possibly a hammer. Additionally, brake cleaner and new brake shoes or kits are essential. Having the right tools on hand will streamline the process and minimize potential frustration.

Step-by-Step Process

1. Preparation Begin by parking your vehicle on a level surface, pulling the parking brake, and loosening the lug nuts. Next, use a jack to lift the vehicle, securing it with jack stands for safety.

2. Removing the Wheel Take off the wheel completely. With the wheel out of the way, you'll have direct access to the drum brake assembly.

3. Removing the Brake Drum The brake drum may be secured by a retaining screw or may need a bit of persuasion if it's rusted on. Carefully remove the screw (if present) and gently tap the drum with a hammer if it won’t budge.

4. Inspecting Components Once the drum is off, inspect the brake shoes, springs, and other components for wear. This is also a good time to check the brake cylinder for leaks, ensuring that the entire system is healthy.

5. Removing Old Brake Shoes Use a brake spring tool to carefully remove the springs and clips that hold the shoes in place. Take a picture or make a note of how everything is assembled, as this will help you when installing the new shoes.

6. Installing New Brake Shoes Place the new brake shoes in the same configuration as the old ones. Reattach the springs and ensure that everything is secured properly.

7. Reassembling the Brake Drum Once the new shoes are secured, reattach the brake drum. If it doesn’t slide on easily, you might need to adjust the shoe's positioning slightly.

8. Finishing Up Reinstall the wheel and lower the vehicle. Finally, tighten the lug nuts and pump the brakes a few times to ensure proper adjustment and function.

Is It Hard?

Whether changing drum brakes is hard largely depends on your comfort level with automotive repairs. For those with basic mechanical skills, this task can be achievable with patience and careful attention to detail. However, for beginners, it may seem daunting due to the intricacies involved with springs and the brake system’s overall assembly.

Final Thoughts

While changing drum brakes might seem challenging, it is a manageable task for those willing to invest the time and effort. By understanding the process and preparing adequately, you can successfully change your drum brakes and enjoy the satisfaction of maintaining your vehicle. Not only does this give you insight into how your car operates, but it also fosters a deeper appreciation for vehicle maintenance. If, however, you find the task too complicated, seeking help from a professional mechanic is always a wise choice.
