The Rear Brake Wheel Cylinder (OEM Numbers: 8-97358878-0 / 3502030-P301 / 8973588780 / 3502030P301) is a premium-quality, direct replacement hydraulic brake component designed specifically for ISUZU NPR75 series medium-duty trucks equipped with 4HK1 diesel engines.
This precision-engineered wheel cylinder is a critical component of the rear drum brake system - it receives pressurized brake fluid from the master cylinder via the brake lines and converts it into mechanical force, pushing the brake shoes outward against the brake drum to slow or stop the vehicle safely and effectively.
