This isn't Tweeter, you are not limited to character count. I'm trying to figure how a calliper leaked and fluid got on to brake pads. Was this a repair you were doing and something happened or did you open it up and see that the calliper was leaking and brake fluid soaked the brake pads.
If your replacing a leaking calliper and the pads are soaked or close, replace the pads with the calliper. If you are installing all new and brake fluid splashed the pads, (and I can't see how that happens) I'd clean them depending on (1.)if it was my car and (2.)I was the only driver, (3.)the pads were not overly cheap. My Neon pads were sometime cheaper than brake cleaner, almost. So it depends on the rest of the story
