Bleeding Brakes...No Fluid Comes Out the Bleeder Screw
I just put on new pads, calipers, and rotors and am now trying to bleed the system. I have filled the resovoir back up and had a buddy pump it until the pedal got stiff. Then he held the pedal down and I loosened the front passenger side bleeder screw. Nothing was coming out so I removed the entire bleeder screw and no fluid comes out! What am I doing wrong here? Does the vehicle need to be on to do this? Could the banjo bolt be in wrong? I didn't see a torque spec for it so I just made it hand tight. Thanks!
Well sounds like your using the proper technique. There's probably a blockage somewhere, i'd bet it's the caliper itself. Did any fluid come out when you cut loose the banjo bolt for the caliper?

Have him pump them up, open the bleeder valve when the peddle goes to the floor close the bleeder valve and have him pump them up again. Repeat this process until you get fluid. Do the furthest wheel from the master cylinder first. And be sure you keep the master cyl. full or you will just get air back in the lines.
banjo bolt should be good n tight, not sure the torque specs but should be way tighter than hand tight. Kinda like the oil drain plug...you just know when it's right. Didn't forget the copper washers between the banjo fitting and the caliper, right?
Just to clarify...pump up the brakes then hold the pedal down fairly hard, while holding the pedal cut the bleeder loose. Your assistants foot should go to the floor. When it's at the floor close the bleeder. Then pump up again, hold and cut loose the bleeder, again to the floor, close the bleeder, etc.. Should usually do that at least 3 times per wheel, checking the fluid level in the reservior inbetween each wheel.
This may sound like a stupid question and I am not real sure you could even do it but the bleeder screw is at the top of the caliper right?
