It could be the adjuster wedges are too short or it could be the shoes are
not quite right.
We ran into the same problem at Grattan a few years ago with John Deikis'
race Midget. We couldn't adjust the rear brakes tight enough to do any
good. I believe all of the parts on John's car were original except for the
shoes. We solved the problem by having a guy with a TIG welder add about
1/16" to the shoes in the area where the adjuster wedge contacts the shoe.
