Good product to install: you could put the proper spacer in and bleed before you mount it pretty easy! Once it is bolted LOOSELY wiggle to get best seating then slowly apply the brake a few times rotate the wheel a bit apply the brake again and snug the bolts each one a bit at a time [go slow]. Try the brake a few time and spin the wheel to ensure one side or worse an edge is not dragging. Then secure to proper spec.
