Construction

• This system has individual control of the front wheels and common control ("Select low") for the rear wheels. "Select Low" means that the rear wheel that would lock first (the one with lowest resistance to lock-up) determines anti-lock brake system activation for both rear wheels.
• The system has a fail-safe function that allows normal braking if there's a problem with the anti-lock brake system.

Construction

In addition to the conventional braking system, the anti-lock brake system consists of: gear pulsers attached to the rotating part of individual wheels; wheel sensors, which generate pulse signals corresponding to the revolution of the gear pulsers; ABS control unit, which controls the working of the anti-lock brake system by performing calculations based on the signals from the individual wheel sensors and the individual switches; modular unit, which adjusts the hydraulic pressure applied to each caliper on the basis of the signals received from the ABS control unit; an accumulator, in which high-pressure brake fluid is stored, a pressure switch, which detects the pressure in the accumulator and transmits signals to the ABS control unit; an ABS pump assembly, which supplies the high-pressure working fluid to the accumulator by means of a pump; a motor relay for driving the ABS pump assembly; fail-safe relays, which cut off the solenoid valve ground circuit when the fail-safe device is at work; and, an ABS indicator light.
