How to Put Drum Brakes Together

Drum brakes are an essential component of a vehicle’s braking system, providing effective stopping power, especially in rear-wheel drive cars. As with any automotive repair, reassembling drum brakes requires patience and attention to detail. This guide will walk you through the process of putting drum brakes back together after maintenance or replacement.

Step 1 Gather Your Tools and Components

Before starting, ensure you have all necessary tools at your disposal, including a brake spring tool, a pair of pliers, a socket set, and a flathead screwdriver. Additionally, gather all components required for the drum brakes brake shoes, springs, adjusters, and the drum itself. It’s crucial to have everything handy to avoid any interruptions during the reassembly process.

Before reassembly, inspect all the components for wear and tear. Check the brake shoes for thickness; if they are worn down, they should be replaced. Also, ensure the springs and other hardware are intact. Replacing any worn parts will ensure optimal brake performance and safety.

Step 3 Install the Brake Shoes

Start by positioning the brake shoes onto the backing plate. The shoes are typically designed to fit in a specific way, with a primary shoe and a secondary shoe. Ensure that the lining of the brake shoes is facing the drum. Attach the shoes using the hold-down springs. Using the brake spring tool can make this process easier. Secure each shoe in place, ensuring they can pivot appropriately.

Step 4 Attach the Adjuster and Springs

Next, install the adjuster mechanism between the two brake shoes. This component helps maintain proper spacing between the shoes and the drum. Follow this by attaching the return springs, which pull the shoes back to their resting position once the brake pedal is released. These springs should be placed correctly to ensure they function effectively.

Step 5 Fit the Drum and Adjust

With the shoes and springs in place, carefully slide the brake drum over the assembled shoes. Spin the drum to ensure it rotates freely. If it’s too tight, you may need to adjust the brake shoes using the adjusting mechanism until the desired clearance is achieved.

Step 6 Final Checks

Before finishing up, double-check all connections and ensure that all components are securely fastened. Reinstall the wheel and lower the vehicle back to the ground. Press the brake pedal a few times to seat the shoes before taking the vehicle for a test drive.

Putting drum brakes together may seem daunting, but with the right tools and a systematic approach, it can be a manageable task. Always remember to follow safety precautions and consult your vehicle’s manual for specific instructions related to your make and model. Happy braking!
