I was just quoted for the complete vacuum line - $125. Ouch and all I need is that C-Clip......

 

Make sure that on each caliper you bleed the outer bleed valve FIRST and then the inner. This is very important! Also bleed in this order: RR, LR, RF, LF. I bleed using the power bleeder but also pump the brake pedal (about 50% of full travel) 3 times per bleed valve. I always have a rock hard pedal using this technique and Endless RF 650 fluid (stock issue on Cup cars).
