Did you clean the platforms where the shoes ride & put a
light film of grease on them? The end of the shoe that fits into the
support plate also needs to be lightly greased. The platforms are the 3
flatspots on the backing plates where the shoes make contact. Also, what about
the condition of the return springs? Do the support plates appear to have
any bends in them & do they operate smoothly? When I did my brakes, I soaked
the support plates in kerosene, since they were loaded with crudd. After that, I
cleaned them well with Brakleen, the solvent based kind & made sure
everything operated smoothly. When you adjust them, snug them up tightly &
back off very slightly. All tightening adjustments are in the direction of the
forward rotation of the respective wheel, with the exception of the BACK
shoe on the rear wheels which are adjusted in the direction of the
respective wheel turning in reverse.
