im saying you have to drill the outer hole at 6 mm for the brake bolt to fit through, then the countersunk nut bit goes in the back but needs a bigger hole, more like 8/10mm but check it with whatever brake you have,
if you drill it all the way through at 8mm the brake bolt will be too loose because they are 6mm
