How to Remove Rear Brake Drums on an Isuzu NPR

The Isuzu NPR is a reliable medium-duty truck widely used in various industries for its durability and performance. Regular maintenance is crucial for optimal operation, and one essential aspect is the brake system, particularly the rear brake drums. This article will guide you through the process of removing the rear brake drums on an Isuzu NPR, ensuring safety and efficiency.

Tools Required

Before starting the removal process, gather the following tools - Jack and jack stands - Lug wrench - Brake cleaner - Screwdriver (flathead) - Rubber mallet - Torque wrench - Protective gloves and goggles

Safety First

Always prioritize safety when working on your vehicle. Park the Isuzu NPR on a flat surface and engage the parking brake. Wear protective gloves and goggles to safeguard yourself against any debris or brake dust.

Step 1 Loosen the Lug Nuts

Using a lug wrench, loosen the lug nuts on the rear wheels while the truck is still on the ground. Turn the lug nuts counterclockwise but do not completely remove them at this stage.

Step 2 Lift the Truck

Position a jack under the frame of the truck, ensuring it is on a strong part of the chassis. Lift the truck until the rear wheels are off the ground. Once elevated, place jack stands under the truck for added safety and stability.

Step 3 Remove the Wheels

Now that the truck is secure, remove the lug nuts completely and take off the rear wheels. Set the wheels aside in a safe area where they won’t roll or cause obstruction.

Step 4 Inspect the Brake Assembly

With the wheels removed, you’ll have access to the brake drums. Before proceeding, take a moment to inspect the brake assembly for any visible wear and tear. This can help identify potential issues that may need attention.

Step 5 Remove the Brake Drum

To remove the brake drum, look for adjustment holes or rubber plugs on the back of the drum. If equipped, use a screwdriver to adjust the brake shoes inward to create clearance. This step is critical as it prevents damage to both the shoes and the drum.

If the drum is still stuck after adjusting, gently tap around the drum with a rubber mallet. This will help to loosen any rust or debris that may be holding it in place. Carefully pull the drum straight off the wheel hub. If it resists, inspect the retaining screws or hardware that may need to be removed.

Step 6 Clean and Inspect

Once the brake drum is removed, use brake cleaner to clean both the inside of the drum and the brake shoes. Inspect the drum for any wear, scoring, or cracking. If the surface is uneven or damaged, it may need to be resurfaced or replaced.

Step 7 Reassemble

If you are replacing or servicing the drum, reverse the removal process. Slide the new or cleaned drum onto the wheel hub. Ensure that the drum fits snugly and rotates freely without obstruction. Replace any hardware that may have been removed during disassembly.

Next, reinstall the rear wheels. Hand-tighten the lug nuts, ensuring they are snug but not over-tightened.

Step 8 Lower the Truck and Finalize

Remove the jack stands, then carefully lower the truck back to the ground using the jack. Once it is securely on the ground, use the torque wrench to tighten the lug nuts to the manufacturer’s specifications, usually outlined in the truck’s manual.

Conclusion

Removing the rear brake drums on an Isuzu NPR can be completed with basic tools and some mechanical knowledge. Regular maintenance of your brake system is vital for the safe operation of the vehicle. Always consult the owner’s manual for specific details related to your truck model, and don’t hesitate to seek professional help if needed. Maintaining your Isuzu NPR’s braking system will ensure its reliability for years to come.
