    I realize this may have to be posted somewhere else but did not see a brake section.


    I have completed the conversion, Willowood front , Inline tube rear with large spin out caliper pistons in rear, dual pistons front.

    22 inches vac, 1979 Corvette style master cyl 1 1/8 inch bore., 8 inch dual diaphragm power booster,
    new 3/16 nickle lines, pressure bled system after installing everything and bench bleeding master.

    Adjusted pedal for 4-1 travel and have hard pedal about 2.5 inch from floor, still car will not panic stop or hard stop for that matter, definitely would not drive.

    Any ideas?

    A smaller diameter master cylinder may help.

    By "hard pedal" are you saying there is no assist?
