How to Remove the Brake Drum from an Isuzu NPR


If you own an Isuzu NPR truck, you know how crucial it is to maintain its braking system for safety and performance. One of the significant components of the braking system is the brake drum, and over time, it may need to be removed for adjustments, inspections, or replacements. This article will guide you through the steps to remove the brake drum from your Isuzu NPR effectively and safely.


Tools and Materials Needed


Before you begin, ensure you have the following tools and materials ready


1. Jack and Jack Stands To lift the truck safely. 2. Lug Wrench For loosening the wheel nuts. 3. Brake Drum Puller This tool will help you remove the drum with ease. 4. Socket Set For removing any bolts connected to the brake system. 5. Brake Cleaner To clean the components once removed. 6. Rags or Towels For wiping down parts and cleaning up. 7. Safety Equipment Gloves and safety glasses for protection.


Step-by-Step Process


Step 1 Safety First


Before you start, ensure the truck is parked on a flat surface. Engage the parking brake and wear your safety gear.


Step 2 Loosen the Wheel Lug Nuts


Using a lug wrench, loosen the lug nuts on the wheel where you’ll be removing the brake drum. Do not fully remove them yet.


Step 3 Lift the Truck


Using the jack, lift the truck from the side where you are working. Once elevated, secure it with jack stands for added safety. It’s crucial never to rely solely on the jack to support the vehicle.


Step 4 Remove the Wheel

Now, remove the lug nuts completely and take off the wheel. This will expose the brake drum and the brake assembly.


Step 5 Inspect the Brake Components

Before proceeding, inspect the brake components for any visible signs of wear or damage. If you notice any issues, now is a good time to take note and possibly replace parts while you have access.


Step 6 Remove the Brake Drum


1. If the brake drum seems stuck, you may need to adjust the brake shoes. Locate the adjuster wheel at the bottom of the backing plate. Use a flathead screwdriver to turn the adjuster until the shoes retract slightly. This can ease the removal process. 2. If the drum is still stubborn, a brake drum puller may be necessary. Attach the puller to the drum according to the manufacturer’s instructions, ensuring it is securely fastened.


3. Once attached, turn the center bolt of the puller slowly. This should gradually pull the drum off the hub. It might take a few moments, so be patient. If you feel considerable resistance, double-check the brake adjuster and ensure there are no other obstructions.


Step 7 Clean and Inspect


Once the drum is removed, take the opportunity to clean it with brake cleaner and a rag. Inspect the inside of the drum for grooves or scoring and check the brake shoes for wear. If either component appears worn beyond limits, consider replacing them.


Step 8 Reassembly


If you are replacing or servicing components, do so following the manufacturer’s specifications. Once you have completed your maintenance, reassemble the brake drum and wheel in reverse order of removal.


Step 9 Lower the Truck


After ensuring everything is securely in place, remove the jack stands and lower the vehicle back to the ground.


Step 10 Test the Brakes


Before hitting the road, pump the brake pedal a few times to ensure the system is functioning correctly. This action helps seat the brake shoes against the drum, restoring braking power.


Conclusion


Removing the brake drum from an Isuzu NPR is a straightforward task if approached methodically and safely. Regular maintenance of your truck's braking system is essential for safety and optimal performance. If you are ever unsure or uncomfortable with any step, do not hesitate to consult a professional mechanic. Your safety on the road is paramount!
