I have a 1997 Explorer with the 302. I recently had to replace the brake line from the rear to the abs pump, my front calipers pads and rotors, and my master cylinder in one shot. I bench bled the master cylinder, then bled the brakes traditionally, I get fluid at all four wheels no air...yet my pedal goes almost to the floor?.... what am I missing? Please help, I only have two more days before school starts and just want normal brakes like everyone else.
