I started to assemble the rear brake on my 1967 BSA A65L. This brake was a leftover from a 1966 - the backing plate is steel - not alloy.
I put the new brake shoes in, and assembled the hub. The brake drags a lot. You can see the high spot it's hitting in one of the attached pictures.
I think I have assembled correctly with the correct spacers. When you drop the brake in, it has plenty of room, but as soon as you tighten the circled nut, the brake locks up.
The brake shoes are brand new Ferodo 65-5940 part numbers. I noticed that the 67 part list
indicates a 68-5940 instead.
Any suggestions as to what is causing the dragging? Have I assembled something wrong? Is there a problem with the brake shoes?
