How to Remove the Rear Brake Drum on an Isuzu NPR

The Isuzu NPR is a popular medium-duty truck known for its durability and performance. Like any vehicle, it requires regular maintenance to ensure optimal operation, and one critical component that may need servicing is the rear brake drum. Over time, brake drums can wear out or become damaged, necessitating their removal and replacement. This guide will provide you with step-by-step instructions on how to safely and effectively remove the rear brake drum from your Isuzu NPR.

Tools and Materials Needed

Before beginning the removal process, gather the following tools and materials

- Lug wrench - Jack and jack stands - Socket set - Brake drum puller (if necessary) - Screwdrivers (flathead and Phillips) - Clean cloths or rags - Brake cleaner - Work gloves and safety glasses

Step 1 Prepare the Vehicle

1. Safety First Ensure that your vehicle is parked on a flat surface and set the parking brake to prevent any movement. 2. Loosen the Wheels Using the lug wrench, loosen the lug nuts on the rear wheels before lifting the vehicle. Do not remove them completely yet.

Step 2 Lift the Vehicle

1. Jack Up the Vehicle Use a hydraulic jack to lift the rear of the Isuzu NPR. Place jack stands under the vehicle's frame for stability. 2. Remove the Rear Wheels Now that the truck is securely elevated, remove the lug nuts completely and take off the rear wheels to access the brake drums.

Step 3 Remove the Brake Drum

1. Inspect for Retaining Screws Some brake drums may have retaining screws that need to be removed. Use a screwdriver to take them out if present. 2. Check for Rust or Corrosion Often, the brake drum can become stuck due to rust or corrosion. If this is the case, gently tap around the drum with a rubber mallet to loosen it. Be careful not to damage any components. 3. Use a Brake Drum Puller (if necessary) If the drum does not come off easily, you might need a brake drum puller. Follow the tool instructions carefully to pull the drum off without causing damage. 4. Remove the Brake Drum Once loose, pull the brake drum straight off the hub. Be cautious as it may be heavy and may contain residual brake components.

Step 4 Inspect and Clean

1. Inspect the Brake Components With the drum removed, check the brake shoes, springs, and hardware for wear or damage. Replace any worn or damaged components as necessary. 2. Clean the Brake Drum Use brake cleaner and a clean rag to wipe down the brake drum, removing any dust or debris that could affect performance.

Step 5 Reinstallation

To reinstall the brake drum, reverse the removal steps

1. If necessary, replace any components and make sure they are correctly positioned. 2. Slide the drum back onto the hub, ensuring it fits snugly. 3. Reattach retaining screws if used. 4. Replace the rear wheels and hand-tighten the lug nuts. 5. Lower the vehicle and completely tighten the lug nuts in a crisscross pattern. 6. Always remember to test the brakes thoroughly before heading out on the road.

Conclusion

Removing the rear brake drum on an Isuzu NPR can be a straightforward task if you follow these steps carefully. Regular maintenance of the brake system is crucial to ensure safe operation of your vehicle.
