sweet as thanks guys thats all i needed to know.

you dont 'need' to. i run a standard m/c unboosted with my setup. and i like the pedal feel and travel.

its personal preference..some prefer a m/c with a larger bore, i havent tried one on mine though

if its already running disks then it shouldnt need to be changed, ive just got my S13 swap done and was told i wont need to.

In goin to be doing the s13 brake swap on my 1200 ute. At the moment it's got 120y struts and disks on it and because of my fairly heated driving habits they're now quite badly worn so im better off putting something decent on there.. The question is, will I need to change the master cylinder in order to run the s13 brakes?
