Thank you all for the help and information. This weekend past I took the rear brake drums off, cleaned the insides and checked the studs for tightness. The right hand side drum needed two shims for adjustment and I found the left hand side the shims had moved up the axel so after taking note of the good advice I cleaned the axel stub, re curved the shim and it must have stayed in place as the brake drum stayed away from the shoes. I was very dubious of the tight axel nut requirements, as in, being wary of striping the axel thread. I dug out the trusty tension gauge set it to 100 lbs and gently brought up to tension. Thank you for the info on using drink cans as a source material for shims. I collected some from the Aero Club bar as I was duty pilot this weekend. I can now set to and the front hubs, thank you for the shim pattern Katty... and re do the brake set up. Many thanks for all the advice.
