Default quick question re pedal boxes

am i right in thinking the smaller the master cylinder 0.ect the higher the pressure ?


ie a .625 mc is more powerful than a .700


if you get me , was having a discussion the other day and a mate belives its the opposite ,

you need to match the master cylinder size with the braking system front and back, I did on the 100E back in the day as I went from drums all round to ap 4pots on the front and 9 inch drums on the back lol
basically bigger pistons (in the calipers) need more fluid to fill the cylinders so you need to push more in there with a bigger master cylinder not the same amount at a higher pressure, if you get my drift

my willwood setup came with two .625's and a .700

i planned on using the 700 for the hydro clutch and the two .625's for the fronts and rears , with a bias vale in the car for small adjustments once the pb is set up
