Non abs I'm assuming...you don't have it so why would you use the one that has it?

I've got a prelude VTEC master cylinder from a 94 VTEC in there. It uses a larger 1" bore vs. 15/16" for better pressure.

I too did an ABS delete on my car since the modulator was leaking. So I used LX/DX front hardlines going to each of the front wheels. Thing is, those hardlines both use the same smaller fitting where the EX/VTEC MC uses a larger one in back. So you'll have to cut/reflare the rear one for a larger size to fit into the VTEC MC.

Pretty easy, it was my first time and I did it fine. Just rent Autozone's reflaring tool and buy a brake line cutter for 6 bucks and buy the correct M12 fittings for the brake line in back (4 bucks for a package)

Also don't forget to add a 40/40 Integra Proportioning valve in place of the ABS stuff since you've got rear discs

Depends HOW it was deleted. We don't know what's in your car, it might be a complete ABS setup with the computer unplugged, or a complete replacement with the non-ABS parts.

Also, a larger master cylinder bore decreases pressure/increases volume.

yeah whoops thats what I meant, I upgraded to bigger 2 Piston Legend GS front brakes so I needed something with more fluid displacement for those larger pistons

I just got a remanned MC from Autozone for 39 bucks. It's a Nissin Reman so it started out its life with good quality parts. It's got a lifetime on it too so if it fails in 50-60k, thats fine, I'll put another in, its not that difficult to do.

the 4040 valve I got from my pick N pull. 5 bucks I think is what it cost me. At Acura dealers they're about 130 new. But scope out any early 90s-late 90s integra with rear disc w/o ABS and you'll find what you need. Shouldn't be that hard to find. I've already found a couple that I've bought and sold within the last couple months.

Use the internet to find some U-pulls, by far the cheapest method of getting things.

I don't know about the prelude MC specifically, but I would stick with ABS parts.

The Prelude VTEC came with ABS standard. It'll work just fine.

I just deleted mine.
I had problems using the non abs mc.
You should re-flare the line in order to reuse the abs mc.
Thats what i had to do and it works great now.

if you want you can run a integra master which is 1" but you gotta use the integra booster. other than that you can do what others posted on here

your best bet is to find a prelude master in the junkyard and cut it and use it. Autoparts stores wont have it since its not a normal thread compared to 10mm

Autozone had the brake line fittings in a small pack of 4

^Hold up. You said that your CB came setup with an ABS M/C, if that's true, then the Prelude VTEC M/C is a direct swap. You will not need to cut and reflare anything if you already are set up for an ABS M/C. You should double check which 1 you have. Is the front flare fitting on the M/C IDENTICAL to the rear flare fitting? If yes, non-abs, if no, abs m/c. Front fitting would be smaller (metric 10 size) vs rear fitting is metric 12 size for ABS. Do not cut anything yet.

EDIT: Just for reference purposes, on an ABS CB, front m/c fitting is metric 10 X 1.00 pitch. rear m/c fitting is metric 12 X 1.00, different sizes. Now, on a NON-ABS CB, both m/c fittings front and rear are metric 10 X 1.00. This was prob. designed to prevent mixing of parts on accident.

yeah he has to reflare the rear fitting for an M12 for the VTEC MC. No biggie. If wors comes to worst and you can't find any, just go to a JY and snip one off a ABS equipped CB7 and you'll have one. But I'd recommend a new one just because they tend to be hard to remove once installed for 20+ years on a car.

^here's what I'm saying, going off of what the OP said: he stated that his 92 EX still has the ABS m/c in his car, meaning the reflare was already done. The ONLY reason he would need to reflare to M12 would be if he had a non-abs m/c setup. For example, I have a 91 SE, came w/ abs, has the proper abs m/c, I could literally bolt in a prelude vtec m/c w/ no mods at all, direct fit, since both are abs. See what I'm saying?

OP should still def. confirm what m/c the car is setup for though. The info is on here but I'll throw this in here too, mixing and matching non-abs/abs m/c's and boosters is a bad idea (diff. pushrod length I believe) keep them as matching pair only.
