Descrizione del prodotto
Brake Master Vacuum Assembly 8-97033988-0 For ISUZU NHR 4JB1 Diesel Truck
The brake master vacuum assembly carrying OEM number 8-97033988-0 combines the vacuum brake booster (servo) and the hydraulic master cylinder into a single factory-assembled unit. It is a direct bolt-on replacement for ISUZU NHR series light trucks powered by the 4JB1 2.8L diesel engine, including NHR55, NHR57, NHR69 chassis from the late 1980s through the late 1990s.
On diesel engines like the 4JB1, vacuum for the brake booster is drawn from a separate engine-driven vacuum pump, rather than the intake manifold as on gasoline engines. This design ensures consistent braking assistance even when the throttle is open or the engine is under load.
A failing vacuum booster typically reveals itself through a hard brake pedal (loss of assist), a hissing sound when pressing the pedal, or engine stalling during braking. A leaking master cylinder leads to a spongy pedal that slowly sinks under steady pressure.
Pre-Assembled Brake Master Vacuum Assembly with Diesel-Specific Vacuum System and Tandem Hydraulic Circuit for ISUZU NHR 4JB1 0
Product Specifications
Part Number:8-97033988-0 8970339880
Product Name:Brake Master Vacuum Assembly
Car Model:ISUZU NHR
Engine Model:ISUZU 4JB1
Condition:100% Brand New
Origin:China Mainland
Main Market:Middle East, Asia, Africa, South America, North America & Europe
Material:High-strength aluminum alloy & precision bearings
Installation:Direct OEM replacement
Quality Standard:OEM equivalent / ISO quality control
Applications
This 8-97033988-0 brake vacuum assembly directly replaces the factory unit in the following configurations:
  • ISUZU NHR55 (1990-1996) - 2.8L 4JB1 naturally aspirated
  • ISUZU NHR57 (1993-1999) - 2.8L 4JB1-T turbocharged
  • ISUZU NHR69 (1995-1998) - late production 4JB1-TC intercooled turbo
  • ISUZU DMAX EXTENDED CAB 4X2 - 2.8L 4JB1 (RLF) with manual transmission, 1993-1999
  • ISUZU TFS SERIES (1997) - diesel cab-chassis configurations
  • ISUZU Faster / KB series (selected markets with 4JB1)
  • Chevrolet W3500 / W4 (rebadged ISUZU NHR, 1990s)
Features & Benefits
Single Pre-Assembled Unit Reduces Installation Time
The booster and master cylinder come pre-assembled and pressure-tested as a pair, eliminating the need for bench-bleeding and component transfer.
Diesel-Specific Vacuum System Compatibility
Designed to operate with diesel-driven vacuum pumps, maintaining consistent assist even at idle.
Tandem Hydraulic Circuit Design
Dual-circuit design ensures braking function is maintained even if one circuit fails.
Replacement for Two Common Failure Modes
Addresses both vacuum booster diaphragm failure and master cylinder seal hardening in one replacement.
Pushrod Adjustable to Factory Specification
Pushrod projection can be adjusted to 18.0-18.2 mm to compensate for wear or deformation.
ISO 9001 Manufacturing with Batch Traceability
Each unit is assembled and tested in an ISO 9001 certified facility with full traceability.
Quality Control & Verification
Each production batch undergoes comprehensive testing:
  • Pushrod projection measurement - set to 18.0-18.2 mm
  • Hydraulic pressure test - 1,200 psi for 60 seconds with zero leakage
  • Vacuum retention test - 500 mmHg with ≤ 2 mmHg pressure drop
  • Thread fit inspection - Go/No-go gauges for outlet ports
  • Mounting flange flatness - within 0.1 mm tolerance
  • Material certification - spectrographic analysis per batch
  • Salt spray testing - ASTM B117, 72 hours, no red rust
Packaging & Supply
  • Individual packaging: VCI sealed bag inside foam-lined carton
  • Carton dimensions: 30 × 30 × 25 cm per unit
  • Net weight: approx. 2.8 kg; Gross weight: approx. 3.5 kg
  • Master carton: 6 units per export carton
  • Lead time: 3-7 working days for stock orders
