How to Remove the Rear Brake Drum on an Isuzu NPR HD

The Isuzu NPR HD is a versatile and robust vehicle commonly used for transporting goods and equipment. Like all vehicles, it requires regular maintenance and repairs, including the brake system. One important aspect of brake maintenance is the removal and replacement of the rear brake drums. This process might seem daunting for someone without experience, but with the right tools and steps, it can be accomplished efficiently.

Tools Required

Before you start, gather the necessary tools

1. Jack and Jack Stands For safely lifting the vehicle. 2. Lug Wrench For removing the wheels. 3. Brake Drum Puller To help remove the drum if it is stuck. 4. Socket Set For various bolts. 5. Wrenches Adjustable and fixed, for different nut sizes. 6. Clean Rag To clean parts during the process. 7. Brake Cleaner For cleaning the brake components. 8. Creeper Optional, but handy for sliding under the vehicle.

Step-by-Step Procedure

1. Safety First Park the vehicle on a flat surface and engage the parking brake. Place wheel chocks in front of the front wheels to prevent any movement.

2. Lifting the Vehicle Use your jack to lift the rear of the Isuzu NPR HD. Once lifted, firmly place jack stands under the vehicle to ensure it is secure.

3. Removing the Wheels Use the lug wrench to loosen and remove the lug nuts on the wheel covering the rear brake drum. After the nuts are removed, take off the wheel, exposing the brake drum.

4. Inspecting the Brake Drum Before proceeding with removal, check the condition of the brake drum. Look for any cracks, deep grooves, or excessive wear. If the drum is damaged, it’s crucial to replace it.

5. Removing the Brake Drum If the brake drum is not coming off easily, it may be stuck due to rust or debris. Use a brake drum puller to gently apply pressure and remove the drum. Follow the manufacturer’s instructions for your puller for best results.

6. Disassembling the Brake Components Once the drum is off, take the time to inspect the brake shoes, springs, and other components. If the shoes are worn down or damaged, they should be replaced. Note the arrangement of the components for reassembly.

7. Cleaning the Components Using brake cleaner, thoroughly clean the brake assembly, including the shoes, springs, and backing plate. A clean surface ensures effective braking and prolongs the life of parts.

8. Installing the New Drum or Components (if necessary) If you are installing a new brake drum, simply slide it onto the wheel hub, ensuring it fits snugly. If you are replacing brake shoes, refer to your notes from disassembly to reassemble them correctly.

9. Reattach the Wheel Place the wheel back onto the hub, securing it with lug nuts. Tighten them in a cross-pattern to ensure even pressure.

10. Lowering the Vehicle Carefully remove the jack stands and lower the vehicle back to the ground using the jack. Once on the ground, perform a final tightening on the lug nuts.

11. Test the Brakes Before driving, pump the brake pedal a few times to seat the new components. Ensure everything is functioning properly before hitting the road.

Conclusion

Removing and replacing the rear brake drum on an Isuzu NPR HD may require some mechanical knowledge and the right tools, but following these steps will lead to successful completion of the task. Always prioritize safety, and don't hesitate to consult a professional mechanic if you're unsure at any stage of the process. Regular brake maintenance is crucial for the safety and reliability of your vehicle.
