Hey guys, I have researched this over and over. I put 4 wheel disc on my 95 civic cx from an integra. I bought a brake master cylinder from 91 civic 4 door ex to put on it but it does not bolt up to the cx brake booster. the flange on the MC is 180 off from the stock civic booster. From what I read the 91 ex MC bolts up but it dosent. What are my options?

Thanks

 

any one know?

 

bump, one last time for some help with this.

 

just take the mc back and put both integra mc and bb in together

 

Also get a 4040 proportioning valve.

I already have a 93 integra 4040 prop valve installed.


i would like to use the 91 civic ex mc since you dont need to bend any lines

 

Does any one who has previously purchased a master cylinder at any of the parts stores (AZ, pep boys, Advance) know the part number for the 91 civic ex 4 door master cylinder.

Thanks

 

I have a 95 DX.. I swapped GSR brakes and had the same prob.. I used the proportioning valve and Master Cylynder from a 94-95 DEL SOL Si V-TEC (B16).. it works flawless..

 

so why not just use the ex 4door booster as well. seems like the easiest thing to do.

 

I believe the EX 4 door was rear drum.. I don't ever recall a 4 door having 4 wheel disc.. the piston size in the master cylynder is different I believe..

 

hey I have a 94-97 1" MC and BB up for sale which is supposed to bolt up to the EG hardlines. I bought the wrong one as I need 98+ to bolt up to my EK. PM me if you're interested and I can send you pics.

 

crx si master cylinder is a direct fit.
i have it on my car and was a little overwhelmed with the diff compared to the stock dx cylinder, had to be careful not to lock up the brakes much faster

 

ex 4door is 4wheel disc.

 

I bought a 91 EX brake master cylinder from Autozone couple years ago. It fits just like the stock CX one.
