The Rear Brake Drum (OEM Numbers: 1-42315377-0 / 1423153770) is a premium-quality, direct replacement brake component designed specifically for ISUZU VC46 series heavy-duty trucks equipped with 6WF1 diesel engines.
This precision-engineered brake drum is mounted on the rear wheel hub and rotates with the wheel, providing the friction surface that brake shoes press against when brakes are applied. The resulting friction converts the vehicle's kinetic energy into heat, slowing or stopping the truck safely and reliably under all load conditions.

Installation Notes
Professional mechanic installation is essential for safety:
Ensure vehicle is safely raised - Use appropriate jack stands or a lift to support the vehicle; remove the rear wheel
Remove the brake drum - Remove the brake drum retaining screws; carefully pull the drum off the hub (use a brake drum puller if necessary)
Inspect brake components - Check brake shoes, wheel cylinders, springs, and hardware for wear or damage; replace if necessary
Clean the hub surface - Thoroughly clean the wheel hub and axle flange; remove all rust, debris, and old grease
Measure the new drum - Use a brake drum micrometer to verify the inside diameter is within specification and roundness is within tolerance
Clean the new drum - Wipe the friction surface with a clean, lint-free cloth to remove any protective coating or debris
Install the new drum - Carefully slide the new brake drum onto the hub; ensure it seats fully against the axle flange
Install retaining screws - Install and tighten the drum retaining screws to manufacturer torque specifications
Adjust brake shoes - Adjust the brake shoe-to-drum clearance to manufacturer specification
Reinstall the wheel - Install the wheel and tighten lug nuts in a star pattern to manufacturer torque specifications
Check brake operation - Pump the brake pedal several times to seat the brake shoes; verify firm pedal feel
Road test - Test the brakes at low speed in a safe area; verify proper stopping performance and no abnormal noise or pulsation
Re-check lug nut torque - After the first 50-100 km, re-check and re-torque the wheel lug nuts
