Brake problem!

[topdog]

Have a 180 with standard brakes, Fitted 4 pots from an s14, Bled the brakes but still no pressure in the pedal. I checked for leaks and there is none. If you pump the brake pedal it will build up pressure and go rock hard but take your foot off it for a few seconds and press it again and it will just go straight to the floor. Im going to fit the standard calipers back on there now and see how it goes but the only thing I an think of that could be the problem is that the banjo bolt fron the 180 calipers was to long to to bolt into the 4pots so I got copper washers to space it out. Its not leaking and I spaced it out properly so dont see how that would cause a problem. Any help or info appreciated.
Thanks

the front calipers are left and right on the 14.i had the same problem on my 13.felt like a sack when i figured it out.never did breaks ever at that stage.so could be differant on the soarer

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

did u open both bleed nipples on one caliper at the same time?either that or you need a bigger bmc 2 accommodate the four pots on front.2 extra pistons like

agreed,ya cant just botch your brakes together and then wonder why they are not working,use all the right parts first and see if it works then and take it from there
