Yeah , these are brand new pads, the piston is completely compressed , but there is not enough space to fit the disc between the outer pad and the mounting bracket. I stripped out my allen head bolt and the head is down in the recess. So does that bolt actually have to come out or can I soak it and force it with channel locks or a C clamp? I have a blaster with the same thing happening, only I'm not yet trying to install the new pads. The old pads , which aren't very old, are all deformed and crooked because this caliper had been forced on somehow, probably crumbling the pad and making it lean. I'm not sure what went on but I know it ruined the pads and it isn't right.
