I am building a 1991 donor into an SSM, and tonight I found this:

Should I replace the rear calipers? I felt that the front calipers were in great shape so I hadn't planned to replace them but I am thinking these rears should go. Any input appreciated.

My opinion, anytime I have a caliper leaking it gets fixed or replaced. Just not supposed to work that way and if the fluid get sot the pad you lost that brake. I had problems with my left front leaking after I had replaced it just a few months before with a NAPA replacement. when I replaced it the first time I did not swap out the bracket that holds the caliper on the front spindle. I also noticed that the pads did not wear even inside to outside.
When it leaked the second time I replaced that bracket which over time can warp and allow the caliper not to be square wit the rotor so lesson learned. Leaking! replace it.

I would pull it apart and see what's wrong. If you can't do that, replace it.

I decided to overhaul the calipers that came with my car. The fronts were fine. Once I pulled the rears apart and inspected them, they became cores for a new set of rears. While there was not an obvious problem with their operation at the time, the pistons and bores did not look good at all. You've definately got one problem because they're not supposed to ooze brake fluid as far as I know. There could be other problems that would make you reconsider using them on a race car too.

I wouldn't race that core even with a rebuild. It doesn't matter how fast you go if you can't stop. ;) If you look around on the road car enthusiast sites you'll see there are some seizure issues with higher mileage calipers, particularly in the rear.
