I need to change my brake fluid before going to the "big to do" at CMP on Labor Day weekend. I remember reading a thread here some time back about using a fluid of different color so you could tell when the new fluid was coming through. I also remember a statement about not using a dye to color the fluid. I've got clear, high temperature brake fluid in now, what brand should I use to flush with so I can tell when I'm getting the new fluid through? Any tricks that may be of help?
