Brake Shoe Assembly LK04442 5-47110-058-1 for ISUZU NKR 2.8/3.4 NPR NKS58 JAC 1040 — Verified OEM Fit Rear Drum Brake Shoe Set Ø320 mm
The Brake Shoe Assembly with reference code LK04442 and OEM number 5-47110-058-1 is a verified direct-fit replacement for ISUZU NKR 2.8 / NKR 3.4 / NPR / NKS58 / NPR58 and JAC 1040 / JAC 1040S light trucks equipped with 4JB1 / 4JB1-T / 4HF1 / 4HG1 diesel engines. This brake shoe is a critical component of the rear drum brake system, responsible for generating braking force by pressing the friction lining against the rotating brake drum when the brake pedal is applied.
The brake shoe is a curved metal platform with a friction lining bonded to its outer surface. It is mounted inside the brake drum on the backing plate and is actuated by the wheel cylinder. When the brake pedal is depressed, hydraulic pressure pushes the brake shoe outward, pressing the friction lining against the inner surface of the rotating drum. This friction converts the vehicle's kinetic energy into heat, slowing and stopping the vehicle.
Replace the brake shoe assembly when any of these symptoms appear:
- Squealing, grinding, or scraping noise during braking — worn friction lining allows metal-to-metal contact between the shoe and drum
- Longer stopping distance — reduced friction coefficient from worn lining compromises braking effectiveness
- Brake pedal pulsation or vibration — uneven lining wear or drum distortion causes pedal feedback
- Visible cracks, glazing, or oil contamination on the friction lining — glazed or contaminated lining loses friction properties
- Brake fluid leakage at the wheel cylinder — oil contamination ruins the friction lining
- Uneven or accelerated tire wear — a dragging brake shoe from a seized adjuster causes uneven wheel rotation

IMPORTANT: Brake system service must be performed by a qualified technician. Never reuse old brake shoes.
- Preparation: Raise the vehicle on a hoist. Remove the wheels and brake drums. Clean the brake assembly thoroughly.
- Removal: Remove the brake shoe return springs, hold-down springs, and adjuster components. Remove the old brake shoes.
- Inspection: Inspect the brake drum for scoring, cracks, or excessive wear. Measure the drum inner diameter. Inspect the wheel cylinder for leaks.
- Installation: Install the new brake shoes onto the backing plate. Reinstall all springs and adjuster components.
- Adjustment: Adjust the brake shoe clearance to specification. Verify proper adjuster operation.
- Final Check: Reinstall the brake drum and wheels. Bleed the brake system thoroughly.
- Road Test: Perform a road test at low speed to verify proper braking performance.
- Every 10,000 km: Check brake shoe lining thickness and inspect for uneven wear
- Every 40,000–50,000 km: Inspect brake drums and shoes. Replace if lining thickness is below minimum
- Every 2 years: Replace brake fluid regardless of mileage
- When brake noise or reduced braking is detected: Inspect brake shoes immediately
- Whenever the brake drum is removed: Always inspect brake shoes and replace if needed
