OK, what is going on here? I have replaced all the brake lines on my '05 with Speiglers and I am bleeding the rear control circuit. I have gone thru an entire 12oz bottle of DOT4 and still I'm getting a constant tiny stream of air in the bleed line. I've tried reverse filling and I've been using the old school method for bleeding to prevent any of the air that does bleed out from going back in. Any chance this air is coming from the bleeder valve?
