My thought is perhaps some of the brake fluid seals are stretching or letting some fluid slip by once the seals warm up a little. If fluid is slipping by seals then this would be seen as a leak in the calipers or wheel cylinders. If fluid is slipping by in the master cylinder this may be not seen as a external leak. In addition brake pads have a cold and hot friction rating. Different brand pads have different ratings.
