| High Light | 8970369290 OEM Fit Brake Vacuum Booster ，8"+9" Tandem Brake Vacuum Booster ，ISUZU NPR 4HF1 Brake Booster | ||
The Brake Vacuum Booster with OEM numbers 8970369290 and 8-97036929-0 is a verified direct-fit replacement for ISUZU NPR / NPR71 / NPR66 / 600P series light and medium-duty trucks equipped with 4HF1 / 4JH1 / 4KH1 diesel engines. This booster utilises engine intake vacuum to create a pressure differential that amplifies the driver's brake pedal force, delivering light, linear braking output even under full-load conditions and effectively reducing driver fatigue on long hauls.
The brake vacuum booster is mounted between the brake master cylinder and the brake pedal. When the pedal is depressed, the control valve opens, allowing atmospheric pressure to enter one side of the booster chamber while engine vacuum acts on the other side. This pressure differential acts on the internal diaphragm, multiplying the pedal force by the boost ratio before transmitting it to the master cylinder piston, thereby achieving sufficient hydraulic pressure with reduced pedal effort. This unit employs an 8"+9" tandem dual-diaphragm design, providing a larger effective boost area than a single-diaphragm booster of the same diameter.
Replace the booster when any of these symptoms appear:
