Product Description
Rear Brake Wheel Cylinder 8-97349705-0 8973497050 For ISUZU NPR NQR NRR N-Series 4HK1-T
Product Overview
OEM Verified Direct fit replacement rear brake wheel cylinder for ISUZU NPR, NQR, NRR, and N-Series trucks equipped with 4HK1-T diesel engine (2003-2018). This critical hydraulic component converts pressure from the master cylinder into mechanical force to activate rear drum brakes.
Key Specifications
- Bore Diameter: 30.16 mm (1-3/16 in) - precision-honed to OEM specification
- Material: Cast iron body with EPDM rubber cups and boots
- Thread Specification: M10 × 1.0 inlet thread (2 ports)
- Position: Rear Left (Driver Side)
- Quality: 100% pressure tested before packaging
- OEM Cross-Reference: 8-97349705-0, 8973497050, 8-97349-705-0, 97349705, 8-97349-705-1, 8973497051
Failure Symptoms & Replacement Indicators
- Brake fluid leak at wheel: Visible wetness around backing plate or inside brake drum
- Spongy or long-travel brake pedal: Pedal sinks further than normal with soft feel
- Uneven braking or vehicle pull: Vehicle pulls to one side during braking
- Brake fade or overheating drums: Extended stopping distances and hot brake drums
- Brake warning light illumination: Dashboard warning with abnormal brake behavior
⚠️ Consequence of Ignoring Symptoms: If left unreplaced, a leaking wheel cylinder can lead to fluid loss, overheated drums, damaged brake components, and complete braking loss on one rear wheel - creating critical safety hazards for loaded commercial vehicles.
