okay, on another note, when i changed my pads last year, i did NOT turn/twist the piston all the way back in (which is what i found out what to do much later) to fit the new pads over the rotors. I only twisted it enough to get the pads just over the rotors....i've only heard this in a few places that this is incorrect because it will cause the piston to be seated wrong.

either way, my brakes work fine, as well as my parking brake. my question is: should i take my brakes apart and twist the piston all the way in, and put it back together so the piston seats correctly?
