Ive got an 02 GT. The drivers front caliper locked up on me so i replaced the caliper, rotor, and pads on that side. When i took the brake line off of the caliper the master cylinder completely drained. When i tried to bleed the brakes i had no pedal at all. Had my son pump the brakes while i bled them. Whats weird is i had clean fluid with NO air coming out of each bleeder. I bleed the front and back lines. After bleeding the entire system i still had NO pedal at all. It goes completely to the floor. I am absolutely stumped as to what the problem can be. Anyone have any ideas? Thanks for your help.
