so here's the story got some new nissin calipers for my 06 zx10 already had galfer braided lines and a brembo master. everything worked fine before i removed the calipers. reused everything crush washers lines everything. i've been trying to bleed them for five hours now and can't get any resistance at the lever. i tried gravity bleeding and the calipers were full of fluid. no i pushed the caliper pistons all the way in and put new pads in and they have not budged. could they be jammed? all of them? i do the pump hold lever down open bleeder close release lever and still nothing. and i don't have a vac. any ideas whats up i can't spot a leak of any kind. thanks guys i'm so ready to see what these calipers do for me its driving me nuts.
