I am on the final stretch of my knuckle job and went to bleed the brakes. Being tired and not paying attention, I added some DOT 5 brake fluide (silicone stuff) to my DOT3 brake fluid. When I got through bleeding the brakes, the waste fluid was like oil and water, a distinct line. THat was my first clue that I had screwed up big time. I assume that I should competely empty the system and start over. Any suggestions on how to "get 'er done" the easiest? Or, have I messed up the rubber stuff...hopefully not. The DOT 3 was looking pretty funky anyway.
