Finally got the Brembo/320mm disc sorted. Hot as hell today for Ireland, around 29degs here in the shade.
Brakes are strong compared to the Nissins I had before and very progressive feel.
The Disc is the same as the XRL kit SM6010C but the bracket that comes with the kit doesn't fit the NX.
Hose mounting is a bit shonky, none of the braided hoses I had were the right length or fittings, I had to use a NOS RMX 250 one that I had lying around which was a bit long.
