How to Take Drum Brakes Apart A Step-by-Step Guide

Drum brakes are a common type of braking system used in many vehicles, particularly older models and some modern compact cars. Understanding how to take drum brakes apart can be beneficial for any car enthusiast or DIY mechanic. This process allows you to inspect, clean, or replace components that may be worn out or malfunctioning. Below is a detailed guide on how to safely disassemble drum brakes.

Tools and Materials Needed

Before you begin, ensure you have the following tools

1. Jack and Jack Stands – To lift and secure the vehicle. 2. Lug Wrench – To remove the wheel. 3. Screwdrivers – Both flathead and Phillips. 4. Pliers – For removing clips and springs. 5. Drum Brake Tool Kit – This may include tools specifically designed for removing springs and adjusters. 6. Clean Cloths – For cleaning and wiping surfaces. 7. Brake Cleaner – To clean components. 8. Replacement Parts (if necessary) – Including brake shoes, springs, and wheel cylinders.

Step-by-Step Process

1. Preparation Start by parked on a flat surface and ensure the vehicle is in gear or has the parking brake engaged. This prevents any unwanted movement while you are working.

2. Jack Up the Vehicle Use the jack to lift the rear or front (depending on the drum) of the vehicle off the ground. Secure it with jack stands to ensure safety.

3. Remove the Wheel Using the lug wrench, loosen and remove the lug nuts from the wheel. Carefully take the wheel off and set it aside.

4. Inspect the Brake Drum Look for any visible signs of wear or damage on the brake drum. If the drum appears to be significantly worn, it may need to be resurfaced or replaced.

5. Remove the Brake Drum You may need to remove retaining screws if they are present. Gently tap the drum with a rubber mallet if it’s stuck. Be cautious not to damage the drum.

6. Take Pictures Before removing any components, take photos of the setup. This can help significantly during reassembly.

7. Remove the Brake Shoes Locate the springs and clips that hold the brake shoes in place. Use pliers and the drum brake tool to carefully unhook these features. Remember the orientation and placement of each component, as this will be crucial for reassembly.

8. Inspect Components Once the shoes are free, inspect them, as well as the wheel cylinder and all springs. Look for signs of wear such as cracks, uneven surfaces, or leaks, and replace parts as needed.

9. Clean the Parts Use brake cleaner and cloths to clean all components. Remove dust and debris to ensure optimal performance once reassembled.

10. Reinstall or Replace Parts If you’re replacing any components, follow the reverse order of disassembly. Make sure each spring and clip is properly positioned as per your reference photos.

11. Reattach the Brake Drum Once everything is in place and secure, reattach the brake drum. Ensure it spins freely without any binding.

12. Reinstall the Wheel Place the wheel back onto the hub, hand-tighten the lug nuts, and lower the vehicle to the ground.

13. Final Tightening With the vehicle on the ground, use the lug wrench to fully tighten the lug nuts in a crisscross pattern to ensure even torque.

Conclusion

Disassembling drum brakes is a straightforward process if approached with care and attention to detail. By following this guide, you can maintain your vehicle’s braking system and ensure its safety and efficiency. Always remember, if you're unsure about any step, consulting a professional mechanic is a wise choice. Keeping a vehicle’s braking system in top shape is essential for safe driving, and being knowledgeable about the parts can help you troubleshoot and maintain your vehicle with confidence.
