If you're lucky a good machine shop could insert a heli-coil into it. I had that done and it worked. But if that fails, then yes, new caliper for you.

I must be getting quicker and braking later as my last track event I too had a little seepage and I can guarantee you mine are not overtightened. I think it is as earlier poster said the seat is just a bit too close to the piston so under high temp it distorts a little and weeps.

I never felt a loss of braking action and only did it after some hard 20 min sessions and smoking brakes but I'm not really worried about it.

I told the dealer and they said that I had bled the brakes wrong. Couldn't have POSSIBLY been the caliper fault.

Any easy way to tell this is happening is when you have a dead pedal until you push fluid back into the caliper. Once you get full pressure back, everything is fine. I've not had this happen to me in quite a while, but I also have taught myself to be better at braking.
