master cylinder swap

91 CRX - disk/drum

I have a 7/8 inch master cylinder. Will a 15/16 in drop in, and is there any advantage to such? I'm not planning any brake upgrades.

Downside? I'd think pedal pressure would go up a little, but other than that...

yeah I used one off of a 90 teg i think, just had to move the lines a lil bit, works like a charm

Yes moving to a larger master cylinder will give you firmer brakes, but with stock rotors your probably going to lock up very easy.
