Tires Squel When I Brake - Why?

[Gregski]

ok, so finally got to test drive the truck after putting that shoe separator back in (had to replace the starter and ignition cylinder key lock - don't ask)

the passenger side rear wheel still locks up, so tomorrow after work I am going to swap the drums and shoes from left to right to see if the problem follows, if it does then it's time for new shoes and I'll have the drums turned, or get new ones if I have to
