Anybody have issues with thier HS33 piston not retracting back completely after braking? Like, after I brake, one side sticks to the rim. I can roll and everything, there's really no rolling resistance but it makes that annoying sound cause it's lightly touching the rim. I can wiggle my bike when rolling to make the noise go away(push the piston away slightly from wheel flex), but it comes back after I use the brake again. I can pull it back (then the other side gets closer) and if I pull it in TOO much, the other side will the the side that sticks. But mostly, it's the same side, I guess what'd be the "master" cause it's the side that the lever hose is attached to. Anybody else have this issue?
