How to Remove the Rear Brake Drum on an Isuzu NPR
Removing the rear brake drum on an Isuzu NPR truck can be a straightforward process if you have the proper tools and understanding of the steps involved. Whether you're replacing worn-out drums, changing brake shoes, or just inspecting your brake components, this guide will help you perform the task safely and efficiently.
Tools and Materials Needed
Before starting, gather the following tools and materials - Jack and jack stands (or a hydraulic lift) - Lug wrench - Brake drum puller - Screwdriver (flathead) - Pliers - Clean rags - Brake cleaner - Safety goggles - Gloves
Step 1 Prepare the Vehicle
1. Park the Truck on a Level Surface Ensure that your Isuzu NPR is parked on a flat area to prevent rolling. 2. Engage the Parking Brake This will add stability while you work on the brakes. 3. Loosen the Lug Nuts Using a lug wrench, slightly loosen the lug nuts on the rear wheel but do not remove them completely at this stage.
Step 2 Raise the Vehicle
1. Jack Up the Truck Using a jack, lift the rear of the truck high enough to remove the wheel. Make sure to place the jack under a sturdy part of the frame to avoid damage to the suspension components.
2. Secure with Jack Stands Once raised, place jack stands under the vehicle to ensure it is stable and secure before you begin working.
3. Remove the Wheel Now that the truck is safely elevated, remove the lug nuts completely and take off the rear wheel to expose the brake drum.
Step 3 Inspect and Remove the Brake Drum
1. Check for Retaining Screws Some Isuzu NPR models may have retaining screws holding the brake drum in place. If present, use a screwdriver to remove these screws.
2. Inspect for Damage Before proceeding to remove the drum, inspect it for cracks or other signs of damage. If there's significant wear, consider replacing it instead of reusing it.
3. Remove the Brake Drum If the drum doesn’t come off easily, you may need to use a brake drum puller. Attach the puller to the drum and turn the handle to pull the drum off the hub. Be cautious as the drum may come off with some force.
Step 4 Work on the Brake Components
1. Inspect Brake Shoes Once the drum is removed, check the condition of the brake shoes. If they are worn down or damaged, it’s a good idea to replace them.
2. Clean the Components Use brake cleaner and a clean rag to wipe down the brake assembly, removing any dust or debris. This will help ensure proper function when reassembled.
Step 5 Reinstallation or Replacement
1. Install New Parts if Needed If you replaced or repaired shoes or other components, ensure they are correctly positioned and securely attached.
2. Reattach the Brake Drum Slide the drum back onto the hub carefully, ensuring no obstruction in the process.
3. Secure with Retaining Screws If your model has screws, be sure to reinstall them.
Step 6 Reassemble the Wheel
1. Put the Wheel Back On Place the wheel back onto the hub and hand-tighten the lug nuts.
2. Lower the Vehicle Carefully remove the jack stands and lower the truck back to the ground.
3. Tighten Lug Nuts Finally, tighten the lug nuts in a crisscross pattern to ensure even pressure.
Conclusion
Removing and replacing the rear brake drum on an Isuzu NPR is a task that can be accomplished with basic mechanical skills and the right tools. Always remember to prioritize safety by using proper lifting techniques and wearing the necessary safety gear. Regular maintenance of your braking system not only improves the performance of your vehicle but also enhances your safety on the road. If you’re ever unsure, consulting a professional mechanic is always a wise choice.
