Okay i thought my brake pins were the wrong length but they are not so.... I have come to the conclusion my problem is @$#% air in the lines. i have taken the new lines i installed apart at various locations between the master and the wheels. I made a cap to cover the lines so i could bleed them a little well i have a pedal with the lines capped all the way till i get to hooking up my w/c sooo i know i have air in the w/c but for the life of me i cant get it out. My chevy shop manual said these brakes have to be bled with a pressure bleeder is that true? If it is ive got to find a cap for my master so i can make a bleeder. or is there another way to bleed these twin wheel cylinders. thanks for the help. Chris eek
