What Master Cylinder

[Tdub90]

i did some searching. and i couldnt find the exact answer i was looking for... i have a 92 ex.. my abs is deleted... what master cylinder do i use... the abs one or the non abs one?... i couldnt find a straight answer.

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.

ok thanks guys.. and right now i cant get a 40/ 40 proportioning valve.. i dont have a way to get it.. so im only running on my front brakes.. cause one of my rear lines blew.. have to buy a new one

[FamousFreak]

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.

i just got back from pepboys.. i bought.. the 94 prelude vtec MC.. i bought a new rear brake line... and i bought the bouble flare tool and tube cutter.... i asked about the M12 fittings and they dont know what im talking about.... does anyone have a part number or know another name for it?.... and again thanks guys

[oneoffaccord]

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
