You need a 15/16 MC

you have 3 choices.

-1991 Honda Civic EX 4-door master cylinder.
-Integra MC + BB
-92-93 Si MC + BB
(I don't know if 94-95 Si are the same because they went to a rear disk set up, they may or may not be)

its really easy to flare lines... just get the tool for it and its a snap

StewPiddass

can we order this '91 part in Canada? I'm gonna look it up at work tomorrow...

I'll need a 40/40 PV too right? from what car? will the EX-v one work? or does it even matter?

what size is the SIR m/c?

and what size is the CTR m/c?


Also...has anyone swapped RSX-S brake setup onto an EK??
does it fit?
I've seen a guy with 5 bolt and rsx-s rims on an EK

Just so people know....the 15/16 m/c mentioned in the original honda tech thread from the 1991 civic ex sedan, cannot be purchased in canada or ordered here.

I had to order and pick mine up from a honda dealership located in buffalo.

imported_My93Civic

U sure? I just called and ask a few places and they seem to have them or can get them. Dunno if its exactly the correct 15/16" one though

imported_My93Civic

I need everyones help ASAP and as much as possible. Thank You.

I just installed the 1991 Honda Civic EX 4-door brake master cylinder in my 1993 Honda Civic DX to replace the old 13/16" one with the new 15/16" version.

My dad and I just bled the brakes for maybe 10 minutes because it was dark and now my the car has NO BRAKES. After we were gonna test it, I kept on pressing the brake pedal down and all you feel is it going to the floor and you can hear a "noise" sounding like a low growl "duehhhhh" when pressing it to the floor.

What can be happening to cause this???

PLEASE HELP ASAP!!!

imported_My93Civic

Got it working. Yay thanks or lackthereof.

imported_JDM-EG6

congrats what was the fix to the problem u were having?

imported_My93Civic

Forgot to remove the old rubber washer thingy. So I left the old one in therre and also kept the new one on the MC thus essentially having 2 rubber pieces in, thus the barrel became shorter.

Dont make the mistake I did. Costed me like a week. LOL

imported_JDM-EG6

ah right on, mine doesnt have anything on right now, so luckly i couldnt forget but thats a good tip and a heads up to people doing this in the future
