First I use two long shoes per wheel, meaning when doing the brakes it takes 2 sets of shoes to do the job.

I also assemble the brakes on the bench, measure the top where they meet and find a socket that is that OD to hold the shoes apart as if they were on the car. Then using 80 grit sand paper, scuff high spots of the shoes until you have 100% lining to drum contact, then adjust until they just scuff the drums, install on car, tighten lugs by hand with spacer to hold drum on, lightly seat drum with hammer and re-adjust on the car just until they hit the drum (There is a tool for it too)

I do this for the front and rear. All backing plates have three spots per shoe where they rub, you should sand this down, and then go to 400 sanded with WD40, then 1000, then 1500 then polish it with metal polish. Do the same with the shoes, and then coat it with Sta Lube synthetic brake grease,,, and your ready to rock!
