    most peps seem to use a 0.6 cylinder which is 5/8 as a fraction or 16mm metric

    Spot on thanks Graham, next thing I have to ask you is. I am going to use a floor mounted pedal box and I see there are a couple of different ratios, one of the Wilwood ones is 5:1 . 5:1 seems to be popular , would that be the ratio I need? I did have a modded Escort one which I know worked well brakes wise.

    iirc an escort pedal box has a 4.1 ratio, which is a bit low for non servo'd brakes, race ones tend to be 5.1 or 6.1 i'd use a 5.1
