The current ABS installation may not be able to warn you of a malfunction. Finding out the brakes aren't operating correctly when you need them is to say the least, problematic. The RAS ABS Brake Control Module Monitor monitors the performance of the last device in the system, so any upstream faults can be detected. Should a fault be detected, within milliseconds of beginning to apply brake pressure, the crew will be notified with both aural and visual warnings allowing the crew to take immediate action to safely bring your aircraft to a stop.
When a brake fault is detected, the fault is stored in the Brake Monitor's memory allowing for quick troubleshooting. If the aircraft power is applied with a fault stored in memory, the ABS INOP indicator will be illuminated, along with a series of aural warnings, notifying the crew before flight that the ABS system is not operating properly.
