I have a 1990 RRC with ABS. I had to disconnect the break lines and replace both front calipers. Prior to doing so, the breaks actually were pretty good. I only replaced the calipers due to one was leaking. Anyways now i have both calipers on and i can not get the breaks to pump up. There are no signs of leaking, just can get them to pump up with any pressure. I got a ton of air out of the lines, im looking for any thoughts anyone may have.
