Clois

Rdorman is correct on the things he has mentioned here, except that I do not know about the adjustable proportioning valve that does more than take pressure away from which ever line you but it in depending on how far you turn it. But there may be one out there. Would not be the first thing that I have not heard of. If not and you are using more front brakes than rear this is not the answer.
What we have to remember here is we are dealing with kits that most of them weigh less than 2,400 lbs. And the track time at the event Clois is talking about was only 15 minute sessions. We are not dealing with 3600 lbs stock cars that race for 2-5 hrs. Are SCCA cars that race from 2-24 hrs. I was at the same event as Clois running Granada front rotors with GM metric calipers with stock pads on front and Pontiac Trans Am rotor with GM metric calipers with stock pads on the rear. With absolutely no brake fade and I ran two consecutive sessions. I was also running with the Group one guys (which is the fastest Group at this show) and so it was not that I was not running hard enough to fade my brakes.

Thanks for posting all the info rdorman. That will be very helpful to a lot of people.

Good luck on solving your problem Clois.

Roger
