Replace it if it's moving that much. But you need to test it with grease, not greaseless leh.. The problem with the silicon o-ring type is you grease need to do it nicely. Can't put too much because it'll compress the grease making the caliper hard to move and then braking failureI havent put it back.
Thats the original pin since 2008.
i know its suppose to move in and out but it can move up and down left and right. Is the other movement instead of in and out are normal or should i replace?
