   Just remember that they're opposite sides...study both sides before you   
   do anything else and you'll see what I mean.

   If they're worn, they could have a groove where the shoes fit the drum and   
   a ridge where they don't. Meaning, there might be a ridge that doesn't   
   allow their removal unless you can find the adjuster wheel and back off   
   the adjustment so the shoes clear the ridge in the drum. I'm no longer   
   familiar with Mopar products, so you're on your own there.

   That happened to my Z28, early on, maybe at 65k. The factory rotors were   
   notoriously thin and any amount of agressive brake use warped them right   
   now. I'll bet every agressive driver will have experienced that in the 4th   
   generation F-bodies.   
      
   I replaced those with an aftermarket rotor made by GM but sold for   
   $150 less per/pair than the same rotor that was on it. These were also   
   drilled and slotted. I also replaced the old pads with Titanium pads.   
      
   The car now has better brakes than it came with from the factory. Which   
   allows the driver to drive deeper into a curve or corner and brake later,   
   increasing the speed through a road course.

    MH> rear caliper clamps that was corroded and not sliding properly.   
      
   Put new drilled and sloted rotors up front, sand the pads on a flat   
   surface if they have high and low spots in them. You'll be happy with the   
   results.
