Removing the Rear Brake Drum on an Isuzu NPR A Step-by-Step Guide

The Isuzu NPR is a versatile medium-duty truck known for its reliability and performance. However, like any vehicle, it requires regular maintenance to ensure optimal safety and functionality. One common maintenance task is the removal of the rear brake drum, which is essential for brake pad replacement or inspection. In this article, we’ll walk you through the step-by-step process of removing the rear brake drum on an Isuzu NPR.

Tools and Materials Needed

Before diving into the removal process, gather the necessary tools and materials - Jack and jack stands - Lug wrench - Brake drum puller (if necessary) - Screwdriver - Torque wrench - Brake cleaner - Safety goggles - Gloves

Safety First!

Safety should always be your top priority when working on any vehicle. Ensure you are wearing safety goggles and gloves to protect yourself from dust and debris. Additionally, work in a well-ventilated area to avoid inhaling fumes or brake dust.

Step 1 Preparing the Truck

Start by parking the Isuzu NPR on a flat and stable surface. Make sure to engage the parking brake to prevent any unwanted rolling. Once the truck is secured, loosen the lug nuts on the rear wheels using a lug wrench. It’s easier to do this while the wheels are still on the ground to prevent them from spinning.

Step 2 Lifting the Vehicle

Next, use a jack to lift the rear of the truck. Place jack stands underneath the vehicle for additional support. Ensure that the truck is stable and secure before proceeding to the next steps. Never rely solely on the jack for support.

Step 3 Removing the Rear Wheels

With the truck securely lifted, fully remove the lug nuts and take off the rear wheels. Set the wheels aside in a safe location. This will give you access to the rear brake drum for removal.

Step 4 Inspecting the Brake Assembly

Before removing the brake drum, take a moment to visually inspect the brake assembly. Look for any signs of wear or damage. It’s essential to note any irregularities that might need to be addressed during reassembly.

Step 5 Removing the Brake Drum

To remove the brake drum, you may need to free it from rust and debris that might have accumulated around the drum's edge. Using a screwdriver, gently pry around the edge if the drum is stuck. If the drum won’t budge, a brake drum puller can be employed to apply even pressure and facilitate removal.

Step 6 Cleaning and Inspection

Once you’ve successfully removed the brake drum, it’s important to clean both the drum and the brake assembly. Use brake cleaner to remove dust and contaminants, ensuring that all surfaces are free from debris. Simultaneously, inspect the brake shoes and other components for wear and damage.

Step 7 Reinstallation

After performing any necessary repairs or replacements and ensuring everything is clean, it’s time to reinstall the drum. Place the brake drum back onto the wheel hub, ensuring it sits correctly. Reattach the wheels and tighten the lug nuts in a star pattern to ensure even pressure.

Conclusion

Removing the rear brake drum on an Isuzu NPR can seem daunting, but following these steps will make the process manageable. Regular maintenance and inspection of your vehicle's brake system are crucial for safety. If you encounter any issues or are unsure at any stage, it’s advisable to consult a professional mechanic. Your safety and the reliable performance of your Isuzu NPR depend on it!
