Unfortunately, it looks as if my re-manufactured rear caliper on the driver side sprung a leak and now the Hawk pads on that side are soaked. It is DOT 4 brake fluid not sure if it makes any difference.
If I didn't spend the extra coin on these pads I would just replace the pads, but curious if the Hawk pads can be cleaned. I see online that the brake fluid is water soluble and the puddle in my driveway cleaned up well. I am just not sure how long it has been leaking since I oddly don't notice a brake pedal feel change.
Update - the pads did not looked soaked but I did wash them off before putting them back on the car. I have not noticed a difference or seen the wheel lock up on hard braking. So far so good.
