Do I need a different master cylinder???

[bgsr240]

OK I know I'm going to get a lot of **** for trying to use these brakes but I am anyway.

I have a set of 180sx brakes from a clip that i bought a while back. I know, I know... they arent really that much bigger. I bought a new set of rotors and pads for them. Everything bolts right of up. Also the pistons between the 240 and 180 calipers look to be same size but the 180's pads are bigger. So I guess I dont have to try to swap MC out. Does anybody have anymore info?

Thanks
