Deskripsi Produk

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.

Part Number:	8-97224374-0 8-97315164-0	Product Name:	Brake Master Cylinder Assembly
Car Model:	ISUZU NKR55	Engine Model:	ISUZU 4JB1
Condition:	100% Brand New	Size:	Standard
Weight:	Standard	Origin:	China Mainland
Main Market:	Middle East, Asia, Africa, South America, North America & Europe
Package:	Neutral Packing Or Make It As Requested
Material:	High-strength aluminum alloy & precision bearings
Installation:	Direct OEM replacement	Quality Standard:	OEM equivalent / ISO quality control

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.
