i just spent about $300 last month on brakes on my stang. well after putting all the brakes on including everything from wheel cylinders to the actual drums i bled the brakes to get all the air out of lines and then for about a week the brakes were fine, however when i was just driving it, the pedal all the sudden went all the way down to the floor and i had no brakes what so ever. i figured that air got back into the lines so i checked all the wheel cylinder connections and nothing was leaking ..what could it be? what do i do? thanks kevin

Check the fluid. Duh. no im kidding. Im not sure i would say air in the lines or one of your wheel cylinders could have blown out.
