Braking system...

BC and Spec are right... My brakes were fine then one day I heard a scratching figured my pads were almost gone and figured I'd change them at the end of the week, it was Weds. Didn't realize the piston had got stuck. By Fri I had no brake pads, no rotors, I was leaking brake fluid all over the place and my brake pedal touched the floor when I pressed it.
