i have a 1966 mustang with the factory 4-piston brake caliper setup in front with a versailles rear setup and 1967 master cylinder. i have never been happy with the performance with this setup from day one, it seems that the brake pedal initally sinks somewhat before you get a solid feel to it and you feel that you almost have to pump it to stop good.
i have ruled out a bad master cylinder because i will get a firm pedal after pumping a couple times. i bled the brakes well so i don't think it's air in the line, i went with small diameter brake lines and wonder if that has something to do with it? i also have a proportioning valve that was for a disc brake car along with a adjustable regulator for the rear brakes.
if anyone else familiar with this setup has any input it would be greatly appreciated. i solved my headlight problems with help from you guys and want to thank you all. one more step to making the car more streetable.
