Re: brake fail and rapid flashing warning light
The servo system must have enough available current to run the pumps up to pressure. A low voltage will cause that to fault out. The BMW test should have been more conclusive as to the cause of the problem. Typically it is in the ABS unit (electronic brain) and not a caliper issue.
Has the system been flushed with new fluid regularly? That can have an impact on internal faults. The brake light switches (handle bar and foot) feed the electronic ABS brain which then drives the brake light relay. If one of these is making contact all the time that can overheat the servo (and cause the brake light to stay on). Make sure they both are adjusted correctly.
