3rd Gen 4Runner Drum Brake Replacement A Comprehensive Guide

The Toyota 4Runner has earned a reputation for its reliability and off-road prowess, particularly in its third generation, produced from 1996 to 2002. However, like any vehicle, regular maintenance is crucial to keep it running smoothly. One essential maintenance task that every 4Runner owner may face is the replacement of the rear drum brakes. In this article, we’ll provide a step-by-step guide on how to replace the drum brakes on your 3rd Gen 4Runner.

Understanding the Components

Before diving into the replacement process, it's vital to understand the components of a drum brake system. The main parts include the brake drum, brake shoes, wheel cylinder, and various springs and retainers. Over time, these components can wear out, leading to reduced braking performance and potentially dangerous driving conditions.

Tools and Materials Needed

To ensure a smooth replacement process, gather the following tools and materials

1. New brake shoes 2. New brake drums (if necessary) 3. Brake cleaner 4. Wrenches and sockets 5. Screwdrivers 6. A jack and jack stands 7. Pliers 8. A brake spring tool (optional, but helpful) 9. Safety goggles and gloves

Step-by-Step Replacement Process

1. Preparation and Safety Park your 4Runner on a level surface and engage the parking brake. Wear safety goggles and gloves for protection.

2. Lift the Vehicle Use a jack to lift the rear end of your 4Runner. Secure it with jack stands to ensure stability while you’re working underneath the vehicle.

3. Remove the Wheel Use a lug wrench to remove the lug nuts and take off the wheel. This will expose the drum brake assembly.

4. Inspect the Brake Drum Before disassembling, inspect the brake drum for grooves or wear. If the drum is excessively worn, it may need to be replaced.

5. Remove the Brake Drum The drum may slide off; however, if it's stuck, gently tap around the edges with a mallet. Once off, inspect the condition of the brake shoes and other components.

6. Disassemble the Brake Components Carefully remove the old brake shoes using pliers. Take note of how the springs and other components are arranged, as you will need to replicate this when installing the new kit.

7. Install the New Brake Shoes Using the reference you noted earlier, install the new brake shoes. Ensure that all springs, retainers, and the wheel cylinder are correctly positioned.

8. Reattach the Brake Drum Once the new shoes are installed, place the brake drum back onto the assembly. Rotate it to ensure it fits properly and is not binding against the shoes.

9. Reinstall the Wheel Place the wheel back onto the hub, hand-tighten the lug nuts, and lower the vehicle back to the ground. Once the vehicle is on the ground, tighten the lug nuts to the manufacturer's specified torque.

10. Test the Brakes Before driving, pump the brake pedal a few times to seat the shoes against the drum properly. Test the brakes at low speed to ensure everything is functioning correctly.

Conclusion

Replacing the drum brakes on your 3rd Gen Toyota 4Runner is a manageable task that can save you money on labor costs and increase your understanding of your vehicle. Regular brake maintenance is vital for safety, ensuring that your 4Runner remains responsive and reliable. If you're unsure at any stage of the process, consulting a professional is always a wise decision. Happy wrenching, and enjoy the peace of mind that comes with new brakes!
