This vehicle has sensotronic brake control (SBC). If the SBC light on the dash illuminates, have the brakes checked. If the SBC is not working, limited brake pressure is delivered to the front brakes, increasing the distance it takes to stop. The SBC hydraulic unit has a specific service life programmed into the control module; follow the manufacturer's recommended service procedure for proper maintenance of the SBC.Google+

I am having the same issue and have discovered that the part is under a 10 year unlimited warranty through the dealer. My independent shop found this out for me. Great help on their part.
