Thomas:

There's also diagrams of this process provided with Zeus brakesets so to say it's not a backyard process..........If I find an extra one I'll send it off to you.

BTW: Not to start a long debate of whether Mafacs are good stoppers or not because I can see it coming!............

With a little finess Mafacs are good stoppers.
