Master Cylinder Sizes

[Luke2842]

Hi all,

I'm a bit stuck with the master cylinder at the moment, my doner was a GLS so have got discs all round but need a master cylinder to suit. From my basic lesson about cylinder sizes from the guy at Rally Designs at Stonleigh is it the case that the bigger the cylinder the less pressure displaced but the harder the pedal. Then the smaller the cylinder the more fluid it displaces but the pedal will be much softer.

Has anyone with the GLS/DOHC models had this problem?

Thanks
