Brake shoes are a crucial component of a vehicle’s braking system, responsible for converting the kinetic energy of a moving vehicle into heat energy, which is dissipated through the brake pads and drums. Over time, brake shoes wear out due to friction and heat, requiring replacement to maintain safe braking performance. In this comprehensive guide, we will walk you through the process of replacing rear brake shoes, highlighting the importance of this task, the necessary tools and materials, and the step-by-step instructions for a successful replacement.
The importance of replacing brake shoes cannot be overstated. Worn-out brake shoes can lead to reduced braking performance, increased stopping distances, and even brake failure, which can result in accidents and injuries. Furthermore, worn-out brake shoes can also cause excessive wear on other brake components, such as the brake drums and rotors, leading to costly repairs.
Before we dive into the replacement process, it’s essential to understand the different types of brake shoes and their characteristics. There are two main types of brake shoes: semi-metallic and non-asbestos organic (NAO). Semi-metallic brake shoes are made from a mixture of metal fibers and organic materials, providing excellent heat dissipation and braking performance. NAO brake shoes, on the other hand, are made from a mixture of organic materials and are designed for use in high-performance vehicles.

Preparation and Safety Considerations
Before starting the replacement process, it’s essential to ensure that you have the necessary tools and materials. You will need a set of brake shoes, brake hardware (such as springs, clips, and pins), and lubricant (such as grease or silicone spray). You will also need a brake cleaner to clean the brake drums and rotors.
It’s also crucial to follow proper safety procedures when working with brake systems. Always wear protective gear, such as gloves and safety glasses, and ensure that the vehicle is securely supported on jack stands. Never work on a vehicle that is supported by a single jack or a hydraulic jack.
Tools and Materials Needed
- Brake shoes
- Brake hardware (springs, clips, and pins)
- Lubricant (grease or silicone spray)
- Brake cleaner
- Jack stands
- Wheel chocks
- Tire pressure gauge
- Socket set
- Wrench set
- Brake lubricant applicator
Preparation Checklist
- Ensure the vehicle is securely supported on jack stands
- Remove the wheel and caliper
- Mark the brake drum for reference
- Remove the old brake shoes
- Inspect and clean the brake drums and rotors
- Apply lubricant to the new brake shoes
- Install the new brake shoes
- Reinstall the brake hardware
- Reinstall the caliper and wheel
Removing the Old Brake Shoes
Removing the old brake shoes is a relatively straightforward process. Begin by loosening the brake spring and brake clip that hold the old brake shoes in place. You may need to use a socket wrench or a brake spring compressor to loosen the spring.
Once the brake spring and clip are loose, you can remove the old brake shoes. Be careful not to damage the brake drum or the brake rotor when removing the old brake shoes. (See Also: How to Reset Parking Brake Bmw X5? Easy Steps Ahead)
Removing the Brake Spring
- Loosen the brake spring using a socket wrench or brake spring compressor
- Remove the brake spring from the brake drum
- Remove the brake clip from the brake drum
Removing the Old Brake Shoes
- Remove the old brake shoes from the brake drum
- Inspect the brake drum and rotor for wear or damage
- Clean the brake drum and rotor using a brake cleaner
Installing the New Brake Shoes
Installing the new brake shoes is a relatively straightforward process. Begin by applying lubricant to the new brake shoes using a brake lubricant applicator.
Once the new brake shoes are lubricated, you can install them in the brake drum. Make sure to align the brake shoe pins with the brake drum and secure them using the brake clip and brake spring.
Installing the New Brake Shoes
- Apply lubricant to the new brake shoes using a brake lubricant applicator
- Install the new brake shoes in the brake drum
- Align the brake shoe pins with the brake drum
- Secure the brake shoe pins using the brake clip and brake spring
Reinstalling the Brake Hardware
Reinstalling the brake hardware is a relatively straightforward process. Begin by reinstalling the brake spring and brake clip that hold the new brake shoes in place.
Once the brake spring and clip are installed, you can reinstall the brake caliper and wheel.
Reinstalling the Brake Spring
- Reinstall the brake spring using a socket wrench or brake spring compressor
- Secure the brake spring to the brake drum
- Reinstall the brake clip to the brake drum
Reinstalling the Brake Caliper and Wheel
- Reinstall the brake caliper to the brake rotor
- Secure the brake caliper to the brake rotor using the brake caliper bolts
- Reinstall the wheel to the brake rotor
- Secure the wheel to the brake rotor using the wheel lug nuts
Testing the Brakes
Once the new brake shoes are installed, it’s essential to test the brakes to ensure they are functioning properly. Begin by driving the vehicle slowly and applying the brakes gently to check for any unusual noises or vibrations. (See Also: What Does Old Brake Fluid Look Like? – Signs To Watch For)
Next, drive the vehicle at a moderate speed and apply the brakes firmly to check for any signs of brake failure or uneven braking.
Testing the Brakes
