U*pdate. I took it in this morning to have the brakes checked. The BAS light went off on the way to the shop. Long story short. They checked every thing out. Brakes, rotors sensors, lines everything looked great. He said the fluid did look a little dirty and the light was on due to a code thrown for the brake switch. He said let's do the flush, clear the code before determining if the switch is actually bad. I, and he thought given the pedal was traveling to the floor, that it may have been triggering the sensor light. So, flushed the fluid, cleared the code and all is well. I now am back to regular brake feel and power and the BAS light has not returned. I drove it about 20 miles and all seems good.

Recommendation is to do the flush and reset the code (logical first step of course) and see if that fixes it. If not, next step is likely the master cylinder. Hope this helps. Good luck and report back.
