Brake Fluid Contaminated Pads July 14, 2020, 08:22:47 AM 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.
