I read on this forum recently about someone swapping out their proportioning valve for a "T" fitting.
Does anyone know the size/thread count of the correct "T" fitting? Any fabrication required? |

Especially as I always race to the corner store for milk and cruise the beach @ 15mph... I can't even get the rear tires to break loose. Knowing that adding this "T" is going to get my car to spin-out is excellent. Does it really make the top speed/HP better? (IMG:style_emoticons/default/beer.gif) |

(IMG:style_emoticons/default/beer.gif) I've personally gone off the road/track backwards into a 12foot ditch at 85mph its real fun... I'm not being a smart ass, I just don't recommend this modification at least I tried it in a controlled environment. bleeding a stock valve when a system has been opened up is a real challenge. I've bled literally 100's of non-teener myself, and once on a 914 restoration I couldn't get my brakes right after a dozen bleed attempts and a few cans of fluid. I took the car to a porsche shop, literally to bleed the brakes. a 250 mile distance by trailer if that helps make my point. try a professional power bleeder, break the lines open, uses the mallet... everything... you'll be impressed with the brakes when you get the air out. oh... pads... the key to good brakes is good pads... try the RS4S |
