100 rear brakes

[Benjamin Kwan <bkwan@lynx.dac.neu.edu>]

Hi all,

	My driver side rear brake is binding against the rotor again. 
This will be the third third time these calipers will be rebuilt.  Is
this a common problem with the 100's and the other 5K series with the
same rear brakes.  It seems to bind up only on the drivers side.  Are
there any alternatives such as aftermarket calipers that are not as
susceptible to getting stuck in the closed position?

Thanks for the help.
