Replacing Drum Brakes on a 3rd Generation 4Runner A Step-by-Step Guide

The Toyota 4Runner is known for its off-road capabilities, reliability, and durability. However, like any vehicle, routine maintenance is essential to keep it performing at its best. One key component that may require attention over time is the drum brake system, particularly on the 3rd generation (1996-2002) 4Runner. If you’re experiencing braking issues or hear a grinding noise when braking, it may be time for a drum brake replacement. In this article, we’ll walk you through the essential steps to effectively replace the drum brakes on your 3rd gen 4Runner.

Tools and Materials Needed

Before starting the brake replacement process, ensure you have the following tools and materials on hand

- Basic hand tools wrenches, sockets, and screwdrivers - Brake drum puller (if needed) - Replacement brake shoes - New brake hardware (springs, clips, and retainers) - Brake cleaner - Grease (for the backing plate) - Jack stands and a jack - Safety goggles and gloves

Step 1 Prepare Your Vehicle

Start by parking your 4Runner on a flat surface and engaging the parking brake. Loosen the lug nuts on the rear wheels slightly while the vehicle is still on the ground. Then, use a jack to lift the rear of the vehicle and secure it with jack stands for safety. Afterward, remove the rear wheels completely.

Once the wheels are off, you can access the brake drums. Inspect for any retaining screws or clips holding the drum in place. If the drum is stuck due to rust or debris, a brake drum puller may be necessary. Carefully remove the drum; if it’s hard to pull off, tap lightly around the edge with a rubber mallet to loosen it.

Step 3 Inspect Components

With the drum off, take a moment to inspect the condition of the brake shoes, springs, and hardware. Look for signs of wear, such as uneven wear patterns, cracks, or thinning on the shoes. If any components appear damaged or worn, they should be replaced.

Step 4 Remove Old Brake Shoes

Before replacing the brake shoes, take note of how everything is assembled, as you’ll need to replicate this when installing new parts. Remove the retaining springs and then the shoes themselves. Be cautious, as the springs can be under tension, potentially leading to injury.

Step 5 Install New Brake Shoes

Starting with the new brake shoes, install them into the backing plate area, aligning them as the old ones were positioned. Reattach the springs and hardware carefully, ensuring everything is securely in place but not overly tight.

Step 6 Clean and Reinstall the Drum

Before installing the brake drum, clean the inside of the drum with brake cleaner to remove any dust and debris. It’s crucial to ensure there are no contaminants on the surface that could affect performance. Once clean, reinstall the drum, making sure it fits snugly.

Step 7 Reassemble and Test

Finally, reattach the wheels, tightening the lug nuts by hand first. Once the vehicle is on the ground, use a torque wrench to properly tighten the lug nuts to the manufacturer's specifications. After everything is securely in place, do a quick brake test.

Conclusion

Replacing the drum brakes on a 3rd generation Toyota 4Runner is a valuable skill for any DIY enthusiast. Not only can it save you money on labor costs, but it also enhances your understanding of your vehicle's braking system. With the right tools and a bit of patience, you can ensure your 4Runner continues to perform safely and effectively on or off the road. Always prioritize safety, and if you feel uncertain at any step, don’t hesitate to consult a professional mechanic.
