rebuilt and installed the front brake caliper on my 73 today. all new seals, pistons, pads, etc. When i put it back on the bike and bled the system, it appears the inner pad is rubbing against the rotor. When i push the bike around i can hear it rubbing, with my eye i can see a space between the pad and rotor on the outside while the brake is released, but the inside looks to be sitting right against the rotor. Is it possible i pushed the inside piston in too far and might be blocking one of the fluid holes?

yeah everything was actually really clean in there, only thing i had a problem with was the threads for the bleed nipple. Pistons were new stainless, and i didn't see or feel any sharp edges or anything on them. i pushed the inside piston in, then did the outside till i could see the fluid holes, when i compared the two after that it seemed the inside one was just a bit deeper, so thought maybe i could be at least semi blocking the holes.concours said:

Can't be much wrong if brake grips good then releases enough not to drag or over heat rotor. The pucks should self center on first good lever pressure application. its the O- ring spring back that retracts pads pressure off rotor but pads are still free to tip and lean over against rotor and its a general feature of all disc brakes that don't glue or clip the pads to the puck, ie: some insignificant touching drag most bounced clear with spun air cushion most the time. My SV650 is floating pad type like Norton and a bugger to get pad to stay put to assemble so I used disc pad organe-red glue to hold them on for a simple non fumble job and maybe more silent. Summary they all do that no worries mate'.
