72 scamp rotor fittment issue

well the one side does seem to be out just a tad more. But they are all the way back. I will post pix tomorrow night. I have the exact same problem both sides. I used the same bearings and hubs that the old rotors used. I tried cracking open bleeder and tried to force pistons back more and they are back as far as they will go. The inner pad has more than enough room but the outer pad lacks about an 1/8th of an inch.
