Do i have to have a z32 brake master cylinder.

[lancaster_sc_rb]

I have an s13 and i have just installed z32 calipers all the wat around. do i need to put on a z32 brake master cylinder do to the fact that the z32 claipers need more fluid. Some say yes. Some say no. My car is a non abs car and there are 3 brake lines that screw into tne master, but every z32 brake master cylinder that i have looked at has only 2 places for brake lines. But there is another port for a 3rd brake line , but when you unscrew the plug there in no place in there for the brake line too seal up against. >>>> What are your thoughts?????

My thoughts are that you suck at searching because this was covered back in 2002

Seriously. Fucking idiot.

Auto S14 master cylinders are 15/16", larger bore, if you're really not capable of finding a Z32 MC with a third port. But we knew this in 1995.

Yeah i used an automatic S14 master cyilnder on my old s14 with Z32 calipers but only in the front though...

Yes if u don't use the mc or I think even the brake booster from a z32 ur brake will feel like somewhat spongy, s13 brake booster big as shit and suck ass

Don't spew lies please.

You need a 15/16" (S14 auto) or larger, but a larger booster is NOT needed. The S13 booster is a single chamber at 230mm. It's big enough. A dual chamber S14 unit (205/180mm) will provide more assist but with the same pedal effort, so it's not required. It also takes up more underhood room. The Z32 booster would be overkill.
