With my vans now on the high seas/even higher sky en route to me, Spanish duties now paid!, I've been doing a bit of research.
Based on the 2 provisos that a), I haven't read all the thread, (slapped wrists), and b), I'm no expert on SR brakegear variations, assuming there are supposed to be full brake yokes not just a connecting bar between the brakeshoes, are there no brake yoke safety loops on this mechanism, or are they in the accessory packet?
Mike.
