How to Remove Rear Brake Drums on an Isuzu NPR

Removing the rear brake drums on an Isuzu NPR is a task that many vehicle owners may need to perform for routine maintenance or repairs. This process can seem daunting, but with the right tools and a bit of know-how, you can tackle this job with confidence. Below, we’ll provide a step-by-step guide on how to safely and effectively remove the brake drums from your Isuzu NPR.

Tools Required

Before you start, gather the following tools

1. Jack and Jack Stands 2. Wheel Chocks 3. Lug Wrench 4. Brake Drum Puller (if necessary) 5. Torque Wrench 6. Screwdriver 7. Rags or Shop Towels 8. Brake Cleaner 9. Safety Glasses and Gloves

Step-by-Step Guide

1. Preparation Begin by parking your Isuzu NPR on a flat, stable surface. Engage the parking brake and place wheel chocks under the front wheels to prevent any movement.

2. Lifting the Vehicle Using the jack, lift the rear of the vehicle. Once elevated, place jack stands under the rear axle to ensure the vehicle is securely supported. Never work under a vehicle supported only by a jack.

3. Removing the Wheels Using the lug wrench, loosen and remove the nuts on the rear wheels. If the wheels are stuck, gently tap them with a rubber mallet to free them from the hub. Once the nuts are removed, take off the wheels and set them aside.

4. Inspecting the Brake Drums With the wheels removed, inspect the brake drums for any visible damage or excessive wear, which may need addressing. If they appear warped or cracked, replacement is advisable.

5. Removing the Brake Drum The brake drum may slide off easily. However, if it is stuck due to rust or buildup, you may need to use a brake drum puller. Attach the puller to the drum according to the manufacturer’s instructions. Gradually tighten the tool until the drum releases from the hub.

6. Cleaning Once the drum is removed, inspect the brake shoes and hardware. Clean the drum and the rest of the brake components with brake cleaner to remove dust and debris. Ensure the back of the drum is free of rust, as any buildup can affect the drum’s performance.

7. Inspecting Brake Shoes While you have access to the brake assembly, check the brake shoes for wear. Look for the thickness of the friction material and inspect the springs and hardware for damage. Replace any worn components as necessary.

8. Reinstalling or Replacing Drums If you are installing new drums, ensure they are the correct size and type for your Isuzu NPR. When reinstalling the drum, simply slide it back onto the hub, ensuring it fits snugly.

9. Wheels Reinstallation Place the wheels back onto the hubs and hand-tighten the lug nuts. Lower the vehicle with the jack, then use the torque wrench to tighten the lug nuts to the specified torque settings indicated in the Isuzu NPR service manual.

10. Final Checks Before driving, pump the brake pedal to ensure the brake shoes seat properly against the drum. This will help eliminate any initial sponginess when you first use the brakes.

Conclusion

Removing the rear brake drums on an Isuzu NPR may take some time and patience, but it is a manageable task for those willing to get their hands dirty. Regular maintenance will not only prolong your brake system’s life but also ensure safety on the road. Always consult your vehicle’s manual for specifics regarding torque settings and brake specifications, and when in doubt, don’t hesitate to seek professional assistance. With practice, you will find this process becomes easier and more familiar each time.
