My Autocrosser, (2005 Saab 9-2X, basically a same year WRX) is experiencing pad knock back with its floating calipers after I recently changed pads/rotors. I tried putting more tension on the anti-rattle springs at the ends of the pads, it's helped some, but it's still got pedal free play. Any of you running floaters have any other ideas? sent from my iPod
