I used a non-ABS 90-93 Integra MC and Brake Booster on my CRX with no problems.

How much difference does the MC make...i used my stock one with the swap and it seems to work fine.

How was I supposed to know that by your original post?

You can use an ABS MC but you have to bend the lines, not sure about the booster though.

I just put a 1" MC and BB off of a '94+ teg(abs, same as ITR) in my CRX.
I'll be running EX rotors(10.3", same as ITR) and '95 Legend GS Calipers(2 piston, same as ITR/NSX), and SS brake lines. (should be AMAZING)

1991 CRX Si compared to '94+ Teg 1"



You have to bend the lines like this-
Don't be scurred. they're not THAT delicate.



Flare the Integra fitting on there. (stock 10mm fitting will not work. This fitting is 12mm from CarQuest.)




End result:




OR

If you want to go the easy route, just buy a 1991 Civic EX Master Cylinder from Advanced auto or the junkyard. It's a 15/16" MC, and provides plenty of pressure to power your DA brakes. It bolts right up to your stock Brake booster, and all the lines match up just fine.

OR...you can just go with the non abs DA MC. No bending of the lines, and with the complete DA brakes, it's exactly how it's supposed to feel.

Don't know yet. My motor should be getting back from my builder this week, so I'll drive it next week and let you know!

Yep, but remember, you have to change the Brake Booster too, unless you can figure out how to get the MC to work upsidedown!

Otherwise, a full DA conversion is awsome.

Another helpful link to give you another idea.

I have the same mc in my crx and the pedel feel great, it does take a lot of vaccum to run it. When I hit the brakes when I am idling and the rpm will go up a little bit but, it is worth it. It is a little over kill but, I going to be running a fastbrakes 4 piston caliper soon.

Andrew Marquis you had it easy with no motor in the car you try is with one in the car it was a bitch trust me on that,

JDM 96 ITR MC and BB dont require any bending

but the only thing with the JDM one is that it comes with a 15/16 MC

For the sake of getting under that very spacious EF dash to undo the 4 bolts of the brake booster...save your energy and use a 88-91 Prelude FI model MC bolts up and is 15/16 same with the 1991 Civic Ex MC...

EX rotors are the same as DA/DC rotors and the ITR rotors are 11 inch

oh and thought the legend calipers are the same as NSX (minus the writing) they are not the same as ITR the ITR are single piston caliper (accord station wagon same)

and the ITR/legend set up will only work on a DA or 90-91 civic EX knuckle on an EF with the 11" redrilled rotor

but you can use the EX/DA/DC rotor on a si/dx knuckle with the ITR/wagon/nsx/legend caliper

you dont need to cut the old fittings off I would just buy a 10-12mm adapter and not cut the line seems easier

ITR/siR calipers are the same with a piston that is about 2 inches...i got a pair of 96 itr calipers and crx siR calipers....

Legend/NSX calipers are almost the same where they are both dual piston but the Legend pistons are bigger. NSX calipers have heat vains, and a better caliper bracket designed for better cooling and the oh so cool "NSX" lettering

and the for those who dont want to change there BB i agree and just use the CIVIC EX MC which is 15/16 and mounts to your factory booster. and you can run a strut bar

You can use a ITR/NSX/Legend/Accord Wagon caliper and caliper bracket with a 90-91 EX kunckle. Please don't say this won't work cause people will beleive it. It will require the use of a redrilled rotor.

It is correct that it will also work on either DA or EX kunckle.

its not false its only half true

I just meant what he was doing wont work he will be about 1/2 " short on the rotor and I forgot about the 90-91 ex I was thinking the 92-95 ex sorry

oh and they both require the use of a redrilled rotor

but you can use the 10.3" rotor on a si/dx knuckle with the itr/legend calipers

I thought you need some spacer as well to line the rotor up?
