Great day out yesterday. Cheers for the ride Spidie. George hasn't stopped talking about it. I've got a few photos and some video, but not very good quality. I'll upload them somewhere when I've got my laptop sorted as it packed up the other day.
I've had another look at my back brakes, and the ones on the right hand side are in very poor condition. The shoes were worn unevenly and were almost down to the rivets at one place. I tried locking the brakes on with just the adjusters and even on max, they just brush the drum and and I can still turn the wheel. Whatever the problems is, these will need replacing. If changing these doesn't let me adjust them up properly, then I'll look at the slaves.
