I put new front lines, rotors, calipers and pads on my 1999 F150 due to rust and wear last week and after bleeding three times and some short trip driving I cannot seem to get them bled completely. On dry pavement I cannot get enough pressure to kick the ABS on, but it does stop in a hurry.
I've been the one under the truck each time and I've had my helper put pressure on the pedal, I cracked the bleeder open with a clear tube attached, watched the flow for bubbles, then closed the bleeder before the flow stopped to avoid sucking in air there. Then repeat this till I see no bubbles.
I have only been doing the two front lines since I didn't open up the rear, should I do all four each time? The reservoir got pretty low as I was replacing the lines. Any other ideas on getting it back where it should be? In "normal" stopping it feels fine and not squishy, just can't get a whole lot of pressure past that.
