Sticking rear calipers and parking brake

[Nick Lawrence]

Doe what others have said for lubing parts and making sure the p/brake 
mechanism in the caliper isn't sticking.  I did ad a greese fitting to my 
calipers to reduce the number of times needed to take apart to free up the 
works.  I just drilled down thru the center of the rotating piece that the 
lever and cable attach to, and tapped for a greese fitting.  Works great.
