Guide to Replacing Drum Brakes on a 3rd Generation 4Runner

A Comprehensive Guide to Replacing Drum Brakes on a 3rd Generation 4Runner

The 3rd generation Toyota 4Runner, produced from 1996 to 2002, is renowned for its durability and off-road capability. However, like any vehicle, the braking system may require maintenance over time, particularly the drum brakes that are utilized in the rear. Whether you're experiencing reduced braking performance or simply following your maintenance schedule, replacing the drum brakes is a task that can be accomplished with some basic tools and patience. This guide will walk you through the process step by step.

Tools and Materials Needed

Before diving into the replacement process, ensure you have the following tools and materials at your disposal

- A jack and jack stands - Lug wrench - Screwdriver (flathead and Phillips) - Pliers - Brake cleaner - New brake shoes - New drum (if necessary) - Rubber mallet - Torque wrench - Gloves and safety goggles

Step 1 Prepare Your Vehicle

Begin by parking your 4Runner on a flat, stable surface. Engage the parking brake and place wheel chocks in front of the front wheels to prevent any movement. Using a lug wrench, loosen the lug nuts on the rear wheels slightly (do not remove them yet) before lifting the vehicle.

Step 2 Lift the Vehicle

Using a jack, raise the rear of the vehicle until it is high enough to comfortably access the rear wheels. Once elevated, secure the vehicle with jack stands for added safety. Now, you can remove the lug nuts and take off the rear wheels.

Step 3 Remove the Brake Drum

After removing the wheel, you will have access to the brake drum. If the drum is rusted or stuck, gently tap it with a rubber mallet to loosen it. Carefully pull the drum off the axle. Inspect the brake drum for wear; if the inner surface is scored or worn beyond the manufacturer's specifications, consider replacing it.

With the brake drum removed, take a moment to inspect the brake components. Look for signs of wear on the brake shoes, springs, and hardware. If any parts appear damaged or excessively worn, they should be replaced. Typically, if the brake shoes are less than 1/4 inch thick, they should be changed.

Step 5 Remove Old Brake Shoes

To replace the old brake shoes, locate and remove the retaining springs and clips. Use your pliers and screwdrivers to gently release the components. Once free, you can pull the old shoes off the backing plate. Take note of how everything is positioned, as you will need to install the new shoes in the same manner.

Step 6 Install New Brake Shoes

Take your new brake shoes and compare them with the old ones to ensure a proper fit. Begin with the primary shoe (the one that contacts the drum first). Position it onto the backing plate and reinstall the retaining springs and clips. Repeat the same process for the secondary shoe.

Step 7 Reinstall the Brake Drum

Once the new brake shoes are securely in place, it’s time to reinstall the brake drum. Slide the drum over the shoes and make sure it spins freely. If it feels tight, you may need to adjust the shoe depth using the star wheel adjuster until the drum fits snugly but allows for rotation.

Step 8 Reattach the Wheel

With the drum back in place, reinstall the wheel and hand-tighten the lug nuts. Lower the vehicle off the jack stands and then finish tightening the lug nuts in a crisscross pattern to ensure even pressure.

Step 9 Test Your Brakes

Before hitting the road, pump the brake pedal a few times to ensure the brake shoes seat properly against the drum. Start the vehicle and perform a gentle test drive to check the brake response. Listen for any unusual sounds and feel for any vibrations, which may indicate a problem with your installation.

Conclusion

Replacing the drum brakes on your 3rd generation Toyota 4Runner is a manageable DIY project that can save you money in labor costs. Regular maintenance of your braking system not only ensures your safety but also prolongs the life of your vehicle. If you are ever uncertain or encounter issues during the process, don’t hesitate to seek professional assistance. Happy driving!
