Rear Brake Drum High-Strength Grey Cast Iron Machined Friction Surface Direct OEM Replacement for Isuzu NPR75 700P

The Rear Brake Drum (OEM Numbers: 8-97102001-0 / 8971020010 and 8-97319056-0 / 8973190560) is a premium-quality, direct replacement braking component designed for Isuzu NPR75 and 700P series medium-duty trucks.

Function: Provides a durable friction surface for brake shoes, converting kinetic energy into heat to slow or stop the vehicle. Ensures reliable braking performance for Isuzu NPR75/700P trucks.

• OE Quality: Manufactured to Isuzu dimensional and material specifications for perfect fit and safe braking
• High-Strength Cast Iron: Premium grey iron alloy provides excellent thermal conductivity and structural integrity under heavy braking
• Optimized Heat Dissipation: External cooling ribs and proper wall thickness reduce heat buildup and minimize brake fade
• Precision-Machined Friction Surface: Smooth, concentric inner surface ensures even contact with brake shoes for consistent stopping power
• Dynamically Balanced: Each drum is balanced to minimize vibration during rotation
• Restores Braking Performance: Eliminates pulsation, vibration, and reduced braking caused by worn or warped drums
• Direct Replacement: Simple bolt-off, bolt-on installation - no modification required
• Cost-Effective: Affordable alternative to genuine OEM without compromising safety

This rear brake drum is specifically designed for Isuzu NPR75 and 700P trucks.

• ISUZU NPR75 (medium-duty truck)
• ISUZU 700P (medium-duty truck)
• May also fit other Isuzu N-series trucks with compatible rear axle - verify

Not engine-specific - fits various engines (4HK1, 4HJ1, 4HE1, etc.)

Installation steps (typical for rear brake drum):

1. Safely lift and support the rear of the vehicle - remove rear wheels
2. Remove the brake drum - if stuck, tap gently with a rubber mallet. If the drum has retaining screws, remove them first
3. Inspect brake shoes and hardware - replace if worn, glazed, or contaminated with oil/grease
4. Inspect wheel cylinder - check for leaks or sticking pistons
5. Measure drum inner diameter - use a drum gauge or micrometer. Compare to maximum diameter stamped on the drum. If beyond limit, replace
6. Clean the new drum - remove protective coating (if any) with brake cleaner before installation
7. Install new drum - slide onto the hub. Ensure it rotates freely without dragging. Adjust brake shoes if necessary
8. Reinstall wheels - torque lug nuts to manufacturer specification (cross pattern)
9. Road test - perform low-speed brake applications to bed in new drums and shoes. Check for abnormal noise or vibration
10. Re-torque lug nuts after 100 km - recommended for commercial vehicle applications

• Material Verification: Cast iron composition tested to ensure GG20/GG25 equivalent properties
• Dimensional Inspection: Inner diameter, bolt pattern, mounting flange thickness, and overall concentricity checked
• Hardness Testing: Brinell hardness verified within OEM specified range (typically HB 180-220)
• Balance Test: Each drum is dynamically checked for imbalance
• Surface Finish Inspection: Inner friction surface roughness measured to ensure proper brake shoe bedding
• Crack Detection: Visual and magnetic particle inspection for casting defects or cracks
• Visual Inspection: 100% checked for casting flaws, burrs, or machining damage
• Packaged Safely: Each drum individually wrapped with rust inhibitor and packed in a sturdy carton

• Neutral export packing or customized packaging available
• Carton or wooden case for safe transportation
• Fast delivery for stock items
• Shipping by Express Air or Sea
