How to Replace the Drum Brakes on a 3rd Generation 4Runner

If you're a proud owner of a 3rd generation Toyota 4Runner (produced between 1996 and 2002), you probably appreciate the vehicle's ruggedness and off-road capabilities. As with any older vehicle, routine maintenance and repairs are essential to keep your 4Runner running smoothly. One key maintenance task you might face is replacing the drum brakes. While this may sound daunting, this article will guide you through the process step-by-step, ensuring that you tackle this task with confidence.

Tools and Materials Needed

Before you begin the replacement process, gather the necessary tools and materials

- Jack and jack stands - Lug wrench - Screwdriver (flathead and Phillips) - Brake drum puller (optional) - Brake cleaner - New brake drums (if needed) - New brake shoes - Brake spring tool - Torque wrench - Safety glasses and gloves

Step-by-Step Process

1. Safety First Always prioritize safety while working on your vehicle. Wear safety glasses and gloves throughout the process. Make sure you’re working in a well-ventilated area, especially if using brake cleaner.

2. Loosen Lug Nuts Start by loosening the lug nuts on the rear wheels while the vehicle is still on the ground. Turn them counterclockwise but do not remove them yet.

3. Lift the Vehicle Use a jack to lift the rear of the 4Runner and secure it with jack stands. This ensures the vehicle is stable while you work.

4. Remove the Wheels Now, remove the loosened lug nuts with a lug wrench and carefully take off the rear wheels. Set them aside in a safe location.

5. Inspect the Brake Assembly Once the wheels are removed, you will see the brake drum assembly. Inspect the components for any visible damage or excessive wear.

6. Remove the Brake Drums If the brake drums are stuck, you may need to tap them lightly with a hammer. Alternatively, a brake drum puller can be used for easier removal. Once removed, inspect the drums for scoring or damage. If they are worn beyond acceptable limits, replace them.

7. Detach the Old Brake Shoes Using a screwdriver, remove the retaining springs that hold the brake shoes in place. Be careful, as these springs can be under tension. After removing the springs, detach the shoes from the backing plate and any associated hardware.

8. Clean the Brake Assembly Before installing new parts, clean the entire brake assembly with brake cleaner. This will remove any dust, debris, and grease that can interfere with the functionality of the new brakes.

9. Install New Brake Shoes Follow the reverse procedure of removal. Install the new brake shoes onto the backing plate. Make sure to position the shoes correctly and use new hardware if the old ones are worn or damaged. Use the brake spring tool to safely install the retaining springs.

10. Replace the Brake Drums Once the new shoes are in place, carefully place the brake drums back onto the hub. Make sure they rotate freely without any dragging or resistance.

11. Reinstall the Wheels Align the wheels back onto the hub and hand-tighten the lug nuts to secure them in place. Lower the vehicle back to the ground and then tighten the lug nuts in a star pattern to ensure even torque.

12. Test the Brakes Before hitting the road, pump the brake pedal a few times to ensure the brake shoes properly seat against the drums and that your braking system is functioning correctly.

Conclusion

Replacing the drum brakes on your 3rd generation 4Runner can seem intimidating, but with the right tools and a bit of patience, it's certainly a task you can handle. Regular maintenance and timely brake replacement are crucial for ensuring your vehicle's safety and performance, especially if you plan on taking it off-road. By following this guide, you’ll not only save money on labor costs but also gain valuable experience working on your truck. Always consult your vehicle’s service manual for specific details and torque specifications. Happy wrenching!
