Brake Caliper rebuild
My right rear caliper is leaking quite a bit. It doesn't look like a brake line at this point, altho I did get a set of stainless from Roger for all the way around, and will put them on. I looked at the other vendor websites, and don't see rebuild kits for the big brakes - it's an 86.5 MY with the big 4 piston S4 brakes.
What would be leaking if not the hoses, and are there repair kits available? If not, who has a used/rebuilt for sale?
TIA

The system has the line with compression ring to the caliper. The caliper has pistons with sealing o-rings and bleeder screws.
Use a good brake cleaner to clean the area and with the wheel off and a 'friend' pumping the brakes look if the leak is external or internal of the caliper.

pumping of the brakes doesn't move anything in the caliper (see my other post). I had my wife pump the brakes with the car running, but no pad movement at all. Not sure what's going on with this.
