ISUZU Brake Wheel Cylinder 8-97139825-0 8971398250 Compatible with NKR NPR 4BD1 4HF1 Diesel Engine — 1-3/16 Inch Bore 16-Tooth OEM Standard Replacement
Part Number Note: This product number is 8-97139825-0 / 8971398250. Cross-reference numbers include 8-97022143-0 / 8970221430 and 8-97022143-1 / 8970221431. Please verify the specific number and installation position based on actual vehicle configuration.
The ISUZU Brake Wheel Cylinder with OEM numbers 8-97139825-0 / 8971398250 is a precision-engineered replacement designed for ISUZU NKR and NPR series light-duty trucks, compatible with 4BD1 and 4HF1 diesel engines. This component is a core actuation element of the vehicle's hydraulic braking system, responsible for converting hydraulic pressure from the master cylinder into mechanical force to push the brake shoes against the brake drum.
The brake wheel cylinder is a critical actuation component of the hydraulic braking system, mounted on the brake backing plate and connected to the master cylinder via brake fluid lines.
| Symptom | Probable Cause |
|---|---|
| Reduced braking performance; increased stopping distance | Worn internal seals; hydraulic leakage; insufficient braking force |
| Vehicle pulls to one side during braking | Single-side cylinder malfunction; uneven braking force |
| Brake drag; vehicle still feels braked after pedal release | Stuck piston; cylinder fails to return |
| Visible brake fluid leakage at the wheel cylinder area | Worn/damaged cylinder seals |
| Soft or spongy brake pedal; increased pedal travel | Internal leakage or air in hydraulic system |
