Ex break master cylinder. Can someone please clarify for me, that the EX master brake cylinder is identical 100% as of the dx, lx, other model Ef’s besides the bore size being 15/16. Meaning it bolts on the same way. I just got back from autozone, and bought a re-man 15/16 ex MC. It the flange is flipped. I’m think it’s a 15/16 integra cylinder. I just had them order me another reman, and the same thing the flange is flipped 180. Doesn’t bolt to my brand new EX Brake Booster.

so now i'm think of ordering a brand new one from NAPA.

 

post some pics if u can.
i recently did the da swap of the mc and booster into my dx sdn. they were totally different.

the mc of the teg is a 15/16 and mine was a 13/16


and the booster bolts are different the u can tell from the vac line on them


not sure if this helps

 

correct the flanges are 180 off.
so i keep thinking the are giving me the integra MC! So i'm going with napa now to order a new one.

oh and since autozone sent out my core they just gave me what they give value for the core. so i'm out of a MC now. As well.

but 'm switching from the LX 13/16 to the Sedan Ex 15/16 and i bought a new EX booster

 

Just to help you verify, I was just running out to my car to grab something, and decided to bring a camera to snap this pic while I was out there. My car is a 1990 EX Sedan, and other than a 5 speed swap, is bone stock, so I hope this helps to verify your situation!
