Morning everyone.thanks for the info, all of a great help.I have sorted the off side brake that was sticky by leaving the hub on the shaft and removing the springs. I removed the automatic adjusting bar and removed .5mm from the face as recommended on the Gomog site. That was the easy bit, getting it back together ain't much fun. It can be done but I figure the job would be a doddle with the hub out of the way. The fix works a treat by the way . The near side brake also needs a shave from the adjusting bar so back to the operating table we go.
Best wishes
