replaced the bad caliper today with a rebuild for $63.00. Car is happy. However I went ahead and flushed the system again even though the fluid looked fine because of the amount of crap I found inside the caliper I tried to rebuild. While doing this I noticed the left rear pads were very low. I replaced these in 6/2000 and figured rear pads should last at least 2x the front. Since the rt. rear were still over 1/2 there I asume the left side is also sticking or was sticking. The dust boots have a couple of holes on this side and from what I can see the pistons have some nasty looking rust on them. Sooooo I guess it's time to replace at least one rear caliper and could be time to replace both. This is a very easy job so not a big deal to do but sucks this time of year as I have other things to pay for right now. Still much less than a car payment so I can't complain to much
