Bleeding Brakes
anyone have a great checklist/how to guide?
see a few tools out there to assist with bleeding but would like some personal experiences behind this routine maitenance item.
and any suggestions on when to replace the disk rotors...starting to feel a lip on mine, front rotors that is. back ones are still pretty smooth.
is there lip depth that says "retire these rotors?"
thanks

Scott,
For your C2 (different recommendation for C4), get yourself a pressure bleeder. Use 2 bar or 30psi pressure. Don't forget to clamp the brake reservoir overflow line before applying pressure, or you'll have brake fluid all over the floor. Follow standard pressure bleeding procedures. Remember you have 2 bleed nipples on each front calipers.
Your front rotors started off at 28mm thick, and should be retired before they reach 26.0mm.
I use, and would recommend, ATE Typ 200 for brake fluid, however, there's a gaggle of brake fluids available. If any question, ensure the brake fluid meets the recommendations in your owners manual (Porsche did change their fluid and flushing recommendation in 1993, although I still recommend annual brake bleeds, and more often for track junkies).
