Front brake master cyclinder
 

I just replaced my front brank master cyclinder due to it had a crack in it. and now i have no brake pressure when im driving. when the bike is sitting at idle the brake lever is hard and i have pressure. when i put it in gear and start rolling i have nothing and can't stop.
I have bleed the brakes and even took the calipers off and bleed them also. but still no pressure. Can anyone think of something that might help me:mad:
