It's what I expected. Brake fluid needed flushin and replacing. Fixed the issue. Mechanic reset the code and all was fixed. The light came on because the pedal went so far to the floor it triggered the warning light. So don't replace any switch until after you flush and replacE the field and the rest the code and test the car.
