I'm looking to upgrade my master cylinder to a 1'' or even bigger if possible..

Any suggestions as to which I could use?

Thanks

Why?

i'm upgrading to some 4 piston calipers up front and the bluebird rears..

I have a 1993 nissan GTS, so i wanted more clamping force with less pedal effort

Old guy

Pressure = Force/Area

So, bigger area means less pressure for the same applied force. However, at the wheel cylinder, Force = Pressure x Area. You will get more clamping force with the larger 4 piston area even if the pressure is lower. What is more important is the balance between front and rear braking.

reverm

Increasing your MC bore will reduce the resultant pedal travel back to reasonable levels, albiet at the cost of increased pedal travel.

Look for an Altima MC. U13 chassis, is the one that swaps direclty onto the B13/B14 chassis, if I remember correctly.
