bought a pair of brakes off eBay only to find they have allen bolt recessed fittings, problem is I have an old frame they is only drilled for standard nut & bolt fitting so I need to either drill the crown/brake bridge to accept the calipers (does anyone know the drill bit size) or is there a device that can overcome the problem without the need to drill?
cheers
