wait, how did you install the calipers and not know where the bleeders are?
you have to bleed the air out of each caliper when the lines are opened... did you put the calipers on, then bleed out the new rubber lines you bought? no.
you are supposed to mount the calipers, install the rubber lines to them, then attach the lines to the hard line mount on the frame of the vehicle, then open the bleeders on the top of each caliper. then have someone press slowly about 3/4 pedal travel and hold, while you tighten the bleeders.
should be either a 8mm or a 10mm box end wrench. and it's best to put a short chunk of clear hose on the nipples of the bleeders to control where the fluid goes.
