One of the calipers is weeping fluid from one of the cylinders which is not good - I think it may be because the cylinders are overextended - pads are gone and worn down to the backing and the rotors are worn too...
I had an issue where stuff blocked the passage for the fluid. I took the caliper off and opened a bleed valve on one side and then used compressed air through the bleeder valve to pop the piston and seal out. Careful because it doesn't take much pressure to shoot the piston out. Repeated on the other side. Cleaned it all up and I just put the piston back in and pressed the seal it with my fingers. It was pretty easy.
