anybody seen a caliper leak out the piston?
I've been chasing a fluid leak in my brakes on the 87wagon. I could find ZERO evidence of lines or external leaks, but it was a very slow leak, so could have been burning off while I drive, anyway, pulled the MC, dry in the booster, put a newer MC on, no change. finally started pulling things apart, and hooked up the power bleeder, pumped up to 15, and started looking for the outlay... found it on the right rear caliper. seeping out around the piston. obviously I have to pull it, I've got a 95 wagon to upgrade to vented rears anyway...
just wondering...

I had on my 420sel leak at the seals around the piston.

You are wondering if it's possible for a seal to leak? Happens frequently.

no, obviously I know they can leak, just wondering how often this occurs, I've NEVER seen one leak this way. I've seen seized pistons, blown flex lines, blown drum brake slaves, rusted hard lines, and bad MC's dump fluid... never seen a caliper piston let go. well, before now that is...

Seems it'd be like a master cylinder seal failing when you push the pedal to the floor. Years of replacing pads when the dealer says to; i.e., lots of life left, then letting the pad wear to the rivets exposes the seal to a section of piston that's corroded from fluid that hasn't been changed in a while. You're right, this scenario means caliper seals would leak all the time.
