I don't see a need to replace the master cylinder right now based on what I know so far. It's a dual cylinder and until I get all the brake work done and start bleeding the system I won't know what condition the master cylinder is in, it would be difficult to replace since the area forward of the fire wall is only accessible from the wheel wells. The right front bake shoes are installed, just need to install the new wheel bearings and it will be complete.

I am working around the daily schedule right now. Yesterday we had the worst rain storm here since hurricane Isabel, everything flooded and I had a doctor's appointment about twenty miles from home. I picked up a large bag full of car parts on the way home and when I got here the day was over. Today won't be much better, I only have this morning to work on the brakes.
