Hey guys I have a 15/16 brake master cylnder in my 95 ex I know its not stock because I had to cuz that brake like that was on the back right od cylinder and put the bigger 12mm nut and reflare the line...

But i think its bad and need to get a new one so can anyone happen to tell me from what model and year civic I could get this for and fit in my 95 civic ex

Symtoms of my brake is feels like air and almost goes to floor but still has brakes. I bleed them a million times and can't get the, to get real tight. I don't see no leaks and fluid stays full...and when I like downs shift and car revs up and makes a lot od vacume or whatever it gets even softer kinda if that makes any sence..

Sorry for the crapy post but ultimately need help finding where I can. Get a replacement brake master cylinder with that will fit me car with that 12mm brakeline nut.

 

if it's this style its off a integra rs (94-97)



if its this way its a 98 rs.
