DYIsland XT-7 hybrid disc brakes.
This looks like a new design to me. (Dont know how to attach images on phone)

yes, i noticed those too. it looks like a modification of the old design w/the pivot moved to the side but the piston generally being the same. maybe it gets you better reliability w/the pivot being further away from all the dirt? my original juin techs were pretty bomb proof, so i don't know if that's fixing a problem or just getting around some IP.
