This guide will provide you with step-by-step instructions to help you safely and efficiently remove the rear brake drum from your Isuzu NPR HD.

Tools and Materials Needed

Before starting the process, ensure you have the following tools and materials

4. Remove the Wheel Now, you can fully remove the lug nuts and take the wheel off. Set it aside in a safe place.

5. Inspect the Brake Assembly Take a moment to inspect the brake components for any signs of wear or damage. This is also a good time to clean the brake area with a cleansing agent to remove dust and debris.

6. Locate the Retaining Screws Most brake drums are held in place by retaining screws. Use a screwdriver to remove these screws. If the screws are stubborn, applying some penetrating oil can help loosen them.

7. Use a Brake Drum Puller Once the retaining screws are removed, you may need to use a brake drum puller to remove the drum. Position the puller on the drum and tighten it until the drum pops off. If you don’t have a puller, you can gently tap the drum with a mallet, but be cautious not to damage any surrounding components.

8. Remove the Drum With the drum loose, gently slide it off the hub. Be aware that the brake shoes may stick to the drum, so a bit of wiggling may be necessary to get it free.

9. Inspect the Drum and Brake Components After removal, inspect the inside of the drum for wear or scoring. Check the brake shoes and other components for any signs of damage or excessive wear.

10. Clean and Service Before reinstalling or replacing components, it’s advisable to clean the drum and brake assembly thoroughly with brake cleaner. This ensures optimal performance and prolongs the lifespan of the new or existing components.

Conclusion

Removing the rear brake drum from an Isuzu NPR HD is a process that requires careful attention and the right tools. By following these steps, you can ensure the job is done safely and effectively. If at any point you feel uncomfortable or unsure, don’t hesitate to consult with a professional mechanic. Proper brake maintenance is crucial for the safety and performance of your vehicle, so take the time to do it right!
