sef u 100% on this i allways thought u had a spaq setup ?

Have a look at the caliper mounting plate, it may have Spaq or scootrs stamped on it. That would be assuming that the master cylinder is the one that came with the hub when new. You know how people chop and change things. Scootrs now use a plate with the Innocenti "I" cut into it but that's only been for the last couple of years.
