Banging brakes

[AustinWood]

My method of getting even brake lining contact is simply to remove the drums and inspect the linings. The area working on the drum is shiny. Were it isn't touching it's dull. I then file the shiny areas carefully with a fairly coarse flat file. After a couple of iterations I get even contact.
If the shoes are at an angle that will show as being shiny on one side of the lining.
