So I went to replace the front pads yesterday and ran into a sticking point. It appears I don't have the correctly sized hex to get off the caliper sliding pins on the back side of the caliper.



Does anyone know the size of these? I tried 8mm, 5/16 which were too small and 10mm and 3/8 seemed to be too large. Also, is it good practice to replace these as well? Slightly frustrated at this point. Thanks for any help on this.
