ISUZU ELF 700P 4HK1 Hydraulic Brake Booster 8-98031414-0 8980314140 — Verified OEM Direct-Fit Brake Servo Assembly
Product Overview

The Hydraulic Brake Booster (BOOSTER; HYDRAULIC BRK) with OEM number 8-98031414-0 — cross-referencing to 8980314140 / 8-97209212-0 / 8972092120 — is a critical safety component of the hydraulic brake system for ISUZU ELF, NPR, NQR, and 700P models equipped with the 4HK1 diesel engine.

Function Overview

The hydraulic brake booster is mounted between the brake pedal and the brake master cylinder. It uses hydraulic pressure supplied by the engine's power steering pump to multiply the force applied by the driver on the brake pedal, then transfers that amplified force to the brake master cylinder. The master cylinder pistons push brake fluid through the brake lines to the wheel brakes at each corner, achieving efficient braking. This component allows the driver to obtain sufficient braking force with reduced pedal effort, making it an indispensable power-assist device in commercial vehicle brake systems.

  • Weight & Logistics Data: Net weight 9.7 KG per piece, H/S Code: 870830000 — supports accurate freight and customs cost calculation
  • OEM Cross-Reference Verified: Replaces 8980314140 / 8-97209212-0 / 8972092120; CARDONE direct cross-interchange 538440; GM/CHEVROLET indirect cross-interchange 8980314140 / 8972092120
  • Installation Fitment: Direct replacement for OEM booster, fits ISUZU ELF/NPR/NQR/700P 4HK1 platforms
  • Genuine Reference Price: ISUZU genuine part market reference price approximately $1,499–$1,799 USD
Failure Symptoms
  • Abnormally hard brake pedal requiring excessive force to decelerate or stop
  • Significantly extended braking distance and delayed brake response
  • No pedal drop when depressing brake pedal with engine running (typical sign of booster failure)
  • Slow or incomplete pedal return after releasing the brake pedal
  • Abnormal air noise or hissing sound from the booster area during braking
Diagnostic method: With the engine off, pump the brake pedal several times to release residual assist, then maintain pedal pressure and start the engine. If the pedal drops noticeably several centimeters after engine start, the booster is working; if there is no drop, the booster has failed.

⚠️ Important: This is a brake system safety component requiring professional repair qualifications for installation. Please provide VIN or chassis number before ordering for fitment verification. Different NPR/NQR year/config variations may use different brake booster models — cross-reference by OEM number is strongly recommended. Brake system bleeding is mandatory after installation.

Quality Control & Verification
QC Item Verification Method
Dimensional inspection CMM coordinate measurement against OEM drawing for key mounting dimensions and port positions
Housing sealing Pneumatic/hydraulic seal test confirming no internal or external leakage
Boost ratio test Bench test confirming boost ratio meets OEM specification
Pedal return test Simulated condition test of pedal return speed and travel
Material hardness Housing material hardness testing to ensure pressure resistance
Visual inspection Visual check for cracks, porosity, corrosion on housing
Packaging inspection Ensure no deformation or damage in transit
The above QC items are industry-standard recommendations. Actual QC standards should be based on supplier inspection reports. As a safety component, brake boosters from suppliers with bench test reports should be prioritized.
Installation & Maintenance Recommendations
⚠️ IMPORTANT SAFETY NOTICE: The brake booster is a core safety component of the brake system. Installation must be performed by professional technicians with commercial vehicle brake system repair qualifications. Brake system bleeding and road testing are mandatory after installation. Always refer to the ISUZU workshop manual.
Installation Guidelines
  1. Disconnect battery negative terminal for safe operation
  2. Disconnect hydraulic lines from brake master cylinder; plug ports to prevent fluid loss and air ingress
  3. Remove old booster connections to brake pedal and master cylinder
  4. Install new booster, ensuring pushrod length matches OEM specification; connect to brake pedal and master cylinder
  5. Tighten mounting bolts to ISUZU-specified torque (consult workshop manual for specific torque values)
  6. Reconnect hydraulic lines, refill brake fluid, and perform brake system bleeding
  7. Start engine and perform the booster function test described above to confirm normal pedal drop
  8. Conduct low-speed road test to confirm normal braking performance
Maintenance Schedule
  • Inspect booster appearance, line connections, and leaks at every service interval
  • Check overall brake system condition including booster function every 40,000–60,000 km or 2 years
  • Inspect booster immediately if hard pedal, extended braking distance, or abnormal noise occurs
