Use a fine file to dress off the roughness and debur the brake post. Crude but effective. Easy peazy lemon squeezy.
This thought crossed my mind, as I'm a bit wary of screwing up the threads completely with a tap or one of the ease-outs. Just to double check though, I'd have to cut the groove into the brake post itself as well (as there's no bolt available above that). I don't imagine it would, but could this detrimentally affect the brake post in any way (i.e. structural integrity)?
Thanks again!
