Re: brake noise..
The squeal is caused by the frequency of the grab-slip of the shoes being the same as the harmonic frequency of the rear drums. Changing the mass or resonance characteristics of the drum will make it will stop.
Some old-time fixes: 1)Wrap a heavy screen-door spring around the drum. Overwrap it with friction tape if necessary to keep it in place. 2)Cut several 1" wide rings radially from an old inner tube. Stretch the bands over the drum. 3)Add a heat-and-shrink steel drum band. You might also try hack sawing 1/16" deep slots 1" apart, at a 45 angle across the shoe linings. If all else fails, get a 1000 watt sound system.
