ya shouldn stack copper washers on your brakes to make the banjo fit thats jus dodgy there should only ever be 2 per banjo...dont think the s14 calipers are supposed to have a banjo bolt if they're like skyline one theres supposed to be a small hard pipe goin into the caliper an a flexi hose that attaches to the hard pipe...try bench bleedin the master cylinder first then stick it back in the car quick an then bleed like normal
