Hey guys, I am having a lot of trouble bleeding out my brakes on the Bronco. I have 4 wheel ABS and just completed my SAS. I have 79 Bronco calipers up front. Nothing changed in the back, I have bled out the lines several times with no air coming out. I can get the pedal to pump up a little bit with the truck off, but after about 20 seconds i hit the pedal and it hits the floor again. With the truck running a cant even get them to pump up. I think there is still air in the lines, but dont know where. There also is nothing that i can see to bleed out the ABS module. 2 weeks agao before i started the SAS the brakes worked great with no problems. I have no leaks anywhere and have been bleeding using the 2 man procedure. Any sugestions?
