C1179 INFINITI Description
The Active Brake Booster consists of vacuum booster, an active booster control group and a delta stroke sensor. In case of brake booster system malfunction due to loss of vacuum the delta stroke sensor will signal the ABS actuator and electric unit (control unit) that a booster failure has occurred. The active booster then applies supplemental force to the master cylinder relative to the amount of force exerted on the brake pedal.
