I know how to upgrade your master cylinder and do the z32 brake swap but this is knowing how to do the z32 front brake only swap and how to upgrade your mc. Below is a link to a thread I started on the KA-T.org forums about which mc to upgrade to.

Can someone who has done the z32 front brake swap with stainless steel lines and at the same time changed out their mc tell me if upgrading to an s13 auto 15/16 mc is good enough to get rid of the mushy brake pedal without being overkill or do i need to upgrade to at least the 1' mc to make it happen??

Auto 15/16 mc is good enough. But if you're buying a new one you may as well get the 300zx.

The reason I would pic an auto mc over a z is b/c I wouldn't have to do anything to get it ready I think. If you just take the auto mc and put it in a manual non abs s13 is it plug and play or do you have to mod it like the 300zx mc's? If you put in a 300zx then you have to cut a fitting out of your stock 240sx mc and put it in the 300zx mc. Not hard but more work. Either way I'm going to be buying a remanied one from autozone and they are about the same price. One just might be easier than the other and provide all i'll need.

well im not to sure bout this, but when i did my 300 front brake upgrade with a mc, my booster went because the old mc was bad, but then replaced the booster, and my pedal is still pretty solid. Now I have been told that it would have been better for me either to use another 240 mc, or have done a full 300z brake upgrade. Not sure if this is acurate, but its what i been trying to work out myself.

z31 15/16 or auto 240 MC......... for the fronts....... neither will have to add a fitting... using the z31 youll have to re do the tubing in placement no biggie...
