ok 93 f150 302 moror 4wd i just changed the oil pan gasket while doing so i hit the brake line that goes from caliper to caliper in the front witha rachet it was rusted out and broke i changed it and all others rusted i bled the brakes to day when finished the brake and abs light is on and the pedal goes to the floor i belive there is air in the abs unit there is a bleeder valve on it does this beed like the rest of the system with pumping the pedal and cracking the the bleeder valve or is the a another way to bleed this by the way i did not have this problem before changing the lines

 

Check online, I am pretty sure there might be a different way of bleeding abs brakes, but, that might be only for the back, the front might be non abs and blead normally.

 

i have never had this problem with abs brakes but i have never totaly had the system dry before i would have to assume bleeding the brakes would be the same i wanted to know if there was a special way to bleed the abs unit its self being there is a bleeder on the unit
