Took a little time, but not too difficult IMHO. The most difficult part for me was trying to get the old pistons out, but was able to do it with some air pressure. If you look at my restoration page below I have some documentation on my caliper rebuild starting at post #13. Rock Auto sells rebuilt calipers for about $50 if you have a good core to exchange. If not, then it will be about $100 per caliper.
