I completed the brake reline on the semi girling front axle, using a set of the woven high friction linings from Dave Cochrane. I was having difficulty setting up the brakes and came across a strange phenomenon. With the adjusters backed off I could fit and remove the drums, but as soon as I tightened the three grub screws the brakes would bind.
I guess this is due to the fact that the girling shoes are not self centering relative to the hub and tightening the countersunk screws showed this up. I finally had a Eureka moment and sprayed the inside of the drum with some primer and then fitted the drum whilst the paint was still wet. With the screws tightened, rotating the drum transferred some paint onto the part of the linings that were catching, which I then gently removed with a rasp. It took me two or three goes to get both drums to rotate without catching when fully home, now all I need is a fine day to road test and bed in. Doesn't sound much, but my back told me it was time for tiffin. ( and a Madeleine )
