How to Put Drum Brakes Together A Step-by-Step Guide Drum brakes are a vital component of many vehicles, providing the necessary stopping power through friction. Whether you're a seasoned mechanic or a DIY enthusiast, understanding how to assemble drum brakes is essential. This guide outlines the steps needed to put drum brakes together properly. 1. Gather Your Tools and Materials Before starting the assembly process, ensure you have the necessary tools. You'll need a socket set, wrenches, tension springs, and a brake shoe tool. Additionally, make sure you have new drum brake kits that include brake shoes, springs, and retainers. 2. Prepare the Brake Assembly Begin by cleaning the brake components. Remove any rust or debris from the brake drum and the backing plate. It’s important to ensure that all parts are in good condition. Check the brake shoes for wear and replace them if necessary. 3. Install the Primary Brake Shoe Identify the primary and secondary brake shoes. The primary shoe is usually positioned toward the front of the vehicle. Attach the primary shoe to the backing plate by positioning it in the correct slot and securing it with the appropriate retaining clips or springs. 4. Attach the Secondary Brake Shoe Next, install the secondary brake shoe. This shoe will be placed behind the primary shoe, and it should also be secured to the backing plate. Make sure both shoes are properly aligned with the brake drum. how to put drum brakes together 5. Connect the Springs Use the brake shoe tool to attach the tension springs. Begin with the lower springs first, as they help hold the shoes in the correct position. After the lower springs are in place, attach the upper springs, ensuring they provide the necessary tension to keep the shoes pressed against the drum when released. 6. Install the Adjuster Mechanism The adjuster mechanism is crucial for maintaining the correct distance between the brake shoes and the drum. Install the adjuster in the designated area between the two shoes and adjust it to the manufacturer’s specifications. This will help ensure optimal braking performance. 7. Finally, Place the Brake Drum Once everything is securely in place, carefully slide the brake drum over the assembled brake shoes. Turn it to ensure there is a smooth fit and that the shoes are not dragging. 8. Test the System Before taking your vehicle on the road, pump the brake pedal a few times to seat the shoes against the drum. Check for any unusual noises or excessive movement and make adjustments where necessary. By following these steps, you can successfully put drum brakes together, ensuring your vehicle's braking system works efficiently and effectively. Remember, safety comes first, so if you’re unsure, consult a professional mechanic.
