rdorman,

I agree with you about the plating possibly being the problem.

Jerry,
Thank for the info and its funny you should say that. keep reading.


I contacted Wilwood and asked them how is it they came up with the solution to my problem. They told me that the setup which I have is the exact setup used in Superformance cars and it works fine.

Ok.....

I contacted Tilton and spoke to the Lead Engineer. I ask him the same question and why is it that it differed from Wilwood. He responded by saying if you contact Wilwood and ask them for a Master Cylinder setup they will almost always respond 3/4 front 7/8 rear regardless of the car.

He told me that the reasoning for the 1 1/8 bore size to the rear is because I am running a large rotor and larger pistons for the rear caliper. At that time he mentioned that he bets that Wilwood did not ask for any specification on my vehicle, which is true. He told because of the large multiple piston size in the rear combined with the large rotor that it will not take much to lock up the rear brakes. He said possibly 250-275 psi to lock the rear and 400-450 to lock up the front.

I am feeling confident that Tilton's suggested method is the better of the two.

I am not sure if this is the solution to my problem or if it is because I had the cylinders plated. By removing the plated cylinders and installing the 7/8 front and 1 1/8 rear, I will eliminate both possiblities.

Tilton also suggested not to run anything above the Wilwood 570 brake fluid because it will eatup the seals over time. He went on to explain that if you are using the car for racing then it does not mater because you should be rebuilding the masters and the calipers more often.

Final result is to order 7/8 and 1 1/8 bore from Tilton. "With out having them plated"

But first I will try to bleed the system individually one last time before I place the order.

Coud some Superformance guys comment on you brake setup please!!!!
