Serious brake-bling going on here. And fitting should be quite straightforward as the lines, cables etc. were already fitted to the rolling chassis.
Calipers/Discs/Pads: Calipers are of the huge AP Racing type; black and shiny. Pads are Pagid RSH 42. And the discs are 330 mm monsters.
Bottom left bracket is where the caliper fits, and fitting should be quite straightforward.
Just a couple of bolts and the flexible line on the back.
