My rear brake caliper seems to be leaking. The inside surface on the rotor is coated with a dirt and brake fluid. Anyone had dealt with this.

You might want to try just tightening the two bolt's that hold it together. Seem one of mine worked it's way loose just a smidge, enough for me to see that the fluid had gone down a little.

 

I haven't noticed my calipers leaking, but my master cylinder leaks when I park it with the brakes locked (under pressure). I do have the metal cylinder on my cat & it has leaked enough down on the fender that the brake fluid ate up one of the decals. It does not leak unless locked & I checked the screws holding the top & they are tight. Anyone else seen this? Is there a gasket between the top & cylinder I need to replace? Thanks for any input.
