Product Overview

The Rear Brake Wheel Cylinder with OEM numbers 8-97358879-0 / 8973588790 is a verified direct-fit replacement for ISUZU NPR, NQR, NRR, and N-Series trucks equipped with the 4HK1-T diesel engine. This critical hydraulic component converts hydraulic pressure from the master cylinder into mechanical force that pushes brake shoes against the drum to slow or stop the vehicle.

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 and feels soft
  • 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 brake warning activates
⚠️ Consequence of Ignoring Symptoms: If left unreplaced, a leaking wheel cylinder can lead to fluid loss, overheated drums, damaged brake components, and complete loss of braking on one rear wheel — creating a critical safety hazard for loaded commercial vehicles.

  5. Clean mounting surface: Remove rust, dirt, and debris from backing plate
  6. Install new cylinder: Position new wheel cylinder and tighten mounting bolts to specification
  7. Reconnect brake line: Connect hydraulic line to inlet port using M10 × 1.0 thread specification
  8. Install shoes and drum: Reinstall brake shoes, adjuster components, and drum
  9. Bleed brake system: Fill master cylinder and bleed system until clear, bubble-free fluid flows
  10. Test brakes: Pump pedal to seat shoes, check for leaks, and road-test at low speed
