So I was changing my brake pads, (please ignore my botchy job on trying to make my calipers red... lol), and the upper bolt's dust boot started to ooz this out. I dont know what it is, is it brake fluid? its not fully liquid, more cream like. It only keeps oozing out if I try to pull back the dust boot on it just a little bit. I dont know what to do or what caused this? Please help.. thank you
