Well, arrived in one piece at my caravan in Bala. The brake seems fine and an improvement on how it was.
I've been for a couple of short blasts since I got here and the brake seems to be a little better again today, might it be that the shoes are making more contact now and starting to bed in properly, or maybe my imagination?
Going to get it apart again when I get home and examine the wear on the shoes, should give me an idea of how it's doing.
