How to Put Rear Drum Brakes Back Together A Step-by-Step Guide

If you're tackling a rear drum brake replacement or repair, understanding how to put them back together is essential. Drum brakes are a vital component of your vehicle's braking system, and reassembling them correctly ensures safety and performance. This guide will walk you through the process step by step.

Tools and Materials You’ll Need

Before you start, gather the necessary tools and materials

- New brake shoes - Brake drum (if needed) - Brake hardware kit (springs, clips) - Brake cleaner - Oil or grease (high-temperature) - Wrenches and sockets - Screwdrivers - Drum brake tool kit (optional but helpful)

Safety First

Before you begin working on your vehicle, make sure it is parked on a level surface. Engage the parking brake and wear safety glasses to protect your eyes from debris. If needed, use a jack to lift the vehicle and ensure it is securely supported with jack stands.

Step 1 Remove the Old Brake Shoes

If you haven't done so already, you'll need to remove the old brake shoes. Start by removing the brake drum. If it’s stuck, use a rubber mallet to gently tap around the drum’s circumference to loosen it. Once removed, take note of how the old brake shoes and hardware are arranged. It is often helpful to take a photo for reference.

Step 2 Clean the Assembly

Using brake cleaner, thoroughly clean the brake backing plate and the inside of the brake drum. This step removes any dirt, dust, and old grease. It’s important to ensure that all surfaces are clean for proper adhesion and functioning.

Step 3 Install New Hardware

Install new hardware from the brake hardware kit. This typically includes springs and clips that secure the brake shoes. Follow the diagram you’ve referenced or the photo you took earlier to ensure correct placement. Use a brake tool if needed for tensioning the springs.

Step 4 Position the New Brake Shoes

Now, take your new brake shoes and place them on the backing plate. The curved side of the shoes should face inward towards the drum. If your braking system uses adjusters, attach them to the brake shoes before securing the shoes to the backing plate.

Step 5 Attach the Springs

Once the shoes are positioned, attach the return springs. These springs pull the shoes away from the drum when the brakes are not engaged. Ensure the springs are securely fitted to allow for adequate tension.

Step 6 Adjust the Brake Shoes

Before you replace the drum, check the adjustment of the brake shoes. There should be minimal clearance between the shoes and the drum. Most systems have an adjustment mechanism (either automatic or manual) that can be tweaked to achieve the desired clearance.

Step 7 Replace the Brake Drum

Carefully slide the brake drum back over the newly installed brake shoes. Spin the drum to ensure it rotates freely. If it feels too tight, you may need to readjust the shoes.

Step 8 Final Checks

Finally, reinstall any retaining clips and ensure everything is tight and secure. It’s also wise to double-check your work before lowering the vehicle. Pump the brake pedal a few times to seat the shoes against the drum before you hit the road.

Conclusion

Reassembling rear drum brakes is a straightforward process if done methodically. By following these steps and paying attention to detail, you can ensure that your braking system functions efficiently and safely. Always refer to your vehicle's service manual for specific guidance related to your make and model, and when in doubt, consult with a professional mechanic. Happy braking!
