in the shop ihave seen guys use line locks when changing calipers(they squeeze the hose so fluid doesnt go everywhere)if line is pinched tthe pedal will feel solid and no braking power for that wheel.
brakes are so important if you have pull when braking it is most likely caliper related
and replace both at the same time
the rears have a star wheel adjuster inside
in most drum brake setups those adjusters are supposed to adjust automatically but they quite often dont.there is several different styles to adjust them (personal preferences)but yes use your e brake frequently , if the rears were adjucsted properly the e brake would have have been set to match so when your e brake travels close to the floor theshoes are wearing down or need another adjustment.
i do the rears in my bII every three months
the rears dont do alot of the braking but they take a big part of the work load from the fronts thusly increasing front brake life
hope this helps sorry bout the bad grammar
