I have put together a brake system for my old muscle car which is set up for track use. I down sized the pistons a bit on the calipers to help with feel, and the results are pretty good, but i have run into an issue, I think i might have made the pistons too small.
It takes a lot of effort to push the brake pedal, but I found that about 3/4th's through the pedal stroke, i reach a plateau of stopping force. If i continue to apply force and press the pedal down to the floor, the brakes do not apply any more force. I figure the pressure is becoming so high in the system that the system itself is beginning to flex and thats where the added leg force goes.
I am using Performance Friction 01 pads, and I believe these pads should be plenty for a car like mine. I could step up to a more aggressive pad, but I really like the 01's because they are so rotor friendly.
But, I'm wondering if my analysis of the situation is correct. I'm running very affordable wilwood calipers, and for a little bit more than the price of new pads, i can get different sized piston calipers. But I want to be sure that this is indeed the issue and that i haven't somehow exceeded the pad's operating range.
