Brake Wheel Cylinder Rubber Cup SC-80423 for ISUZU NKR 100P / NPR — Verified OEM-Fit Rear Wheel Cylinder Cup Seal, 1 Inch
The Brake Wheel Cylinder Rubber Cup with reference code SC-80423 is a verified direct-fit replacement for ISUZU NKR 100P / NPR light trucks. This rubber cup is a critical component of the rear drum brake hydraulic system, responsible for sealing hydraulic pressure inside the wheel cylinder and ensuring reliable braking force transmission.
The brake wheel cylinder rubber cup is the primary hydraulic seal inside the wheel cylinder. It converts hydraulic brake fluid pressure into mechanical force that pushes the brake shoes against the brake drum. The cup-shaped design features a precisely angled sealing lip that expands under hydraulic pressure — the tighter the braking force, the tighter the seal.
This rubber cup is manufactured by Jingzhong (贵州精忠橡塑实业有限公司), a professional rubber and plastic manufacturer with ISO/TS 16949:2009 quality system certification, using an NBR (Nitrile Butadiene Rubber) compound for excellent resistance to DOT 3 / DOT 4 brake fluid, heat, and compression set.
Replace the brake wheel cylinder rubber cup when any of these symptoms appear:
⚠️ Critical Inspection Note: ISUZU service manuals require that when rebuilding a wheel cylinder, both cup seals and dust boots must be replaced as a complete set per wheel. Prior to installation, the cylinder bore must be inspected for scoring or pitting — if damaged, the entire wheel cylinder assembly must be replaced. New cups must be lubricated with clean brake fluid and installed with the sealing lip facing the hydraulic pressure source.
