Product Description
Brake Master Cylinder Assembly 8-97224374-0 8-97315164-0 For ISUZU NKR55 4JB1 2.8L Diesel Truck
Product Overview

The brake master cylinder assembly carrying OEM numbers 8-97224374-0 and 8-97315164-0 (also 8972243740, 8973151640) converts mechanical brake pedal force into hydraulic pressure for the braking system on ISUZU NKR55 series light‑duty trucks powered by the 4JB1 2.8L diesel engine. These interchangeable part numbers refer to the same tandem master cylinder design used across NKR55 chassis from the late 1980s through the mid‑1990s.

Vehicle Applications

This ISUZU NKR55 brake master cylinder assembly directly replaces the factory unit in the following configurations:

Chassis Engine Years Notes
ISUZU NKR55 4JB1 (naturally aspirated) 1988-1994 Light cab‑over, standard GVWR
ISUZU NKR55E 4JB1‑T (turbo) 1990-1998 Turbocharged variant
ISUZU NKR55G 4JB1 1992-1998 Updated chassis
ISUZU NKR57 4JB1 1988-1994 Slightly longer wheelbase - same master cylinder
ISUZU NPR (early) 4JB1 1988-1994 Some NPR trucks share this cylinder
ISUZU KB / Rodeo 4JB1‑T 1990-1998 Pickup trucks with 2.8L diesel
Key Features & Benefits
Tandem (Dual‑Circuit) Design for Fail‑Safe Braking

Contains two independent pistons in series. If one circuit fails due to leakage, the other circuit retains hydraulic pressure for reduced but functional braking.

Aluminum Alloy Housing Resists Corrosion

Die‑cast aluminum body prevents rust and extends service life in coastal or winter‑salt regions. Bore is anodized or hard‑coated for wear resistance.

EPDM Seals Compatible with DOT 3 / DOT 4 Brake Fluid

Formulated EPDM rubber seals resist swelling and hardening caused by moisture absorption - the primary cause of seal failure in older master cylinders.

Integral Reservoir with Fluid Level Sensor Port

Includes provision for brake fluid level sensor with translucent reservoir for visual fluid level checking. Capacity: approx. 0.3-0.4 liters.

Direct Bolt‑On Replacement - No Modifications

Four‑stud mounting flange matches NKR55 firewall exactly. Installation typically takes under one hour with no adapter plates or line bending required.

100% Pressure‑Tested Before Packing

Each unit undergoes hydraulic pressure testing at 1,200 psi (83 bar) for 60 seconds while submerged. Certificate of conformance available for wholesale orders.

Quality Control & Verification
QC Item Verification Method
Bore diameter and finish Air gauge and profilometer - 23.81 mm ±0.02 mm, Ra ≤ 0.4 µm
Piston seal integrity Low‑pressure test: 2 bar applied to outlet; measure pressure decay over 10 seconds
High‑pressure external leakage 1,200 psi for 60 seconds, submerged in test fluid - zero bubbles
Reservoir attachment seal Vacuum test on reservoir chamber - no air ingestion
Port thread accuracy Go/No‑go gauges for M10 × 1.0 threads
Pushrod bore alignment Fixture check - clevis/fork interface square to mounting flange
Return spring force Spring dynamometer - force measured at 50% compression
Material certification Spectrography on housing batch - aluminum alloy grade

Manufacturing facility holds ISO 9001:2015 certification with 12‑month warranty against manufacturing defects. Certificate of analysis with batch traceability available for wholesale orders.
