ABS Braking

ABS braking
2.1 Maintaining Pressure





After the ABS control unit detects wheel lock due to excessively increased pressure, the ABS control unit closes the inlet valve to avoid further increase in hydraulic pressure.

2.2 Decreasing pressure





If wheel lock continues, the ABS control unit opens the corresponding outlet valve so that brake fluids flow to the pressure accumulator. This reduces pressure only for wheels that are locked.

2.3 Increasing pressure





When wheels have been returned to normal speed from locking, the ABS control unit stops operating the solenoid valve and returns to standard braking operation.
