I have a 92 Honda civic Lx, Also I have All rear disc brake system from 92 acura Integra to put in my civic. Is true I need to change the proportion valve and the master cylinder? if is true, what kind is and where I can find It. (web page) and it is true can I use Integra 4040 prop valve

My car don't have ABS, and the front disc brake is the original from the car, the rear disc brake is original from acura integra 92, and the original master cilinder is 13/16. I need change any way the master cilinder and the promp valve?
if so which one I need

Well since you are upgrading your brake system the word on the street is to upgrade to a larger mc/brake booster for example 15/16 size mc and use the 40/40 proportioning valve.
Now do you have too? Well there's only one thing that we all have to do and that is to cease to exist.
You can find all you need here on H-T marketplace or craaglist or local junk yards and just be careful on the proportioning valve:if your car does not have abs make sure the 40/40 valve is not from a car with abs. and vice versa

NOO, look around your MC for the size, I'm not sure what siz yours would be, if it's 7/8 or bigger, You will be fine.

As for the prop valve. again it is NO needed. The best thing to do is get the right size MC and booster first, if needed. Get your swap done, bleed and working. Drive it and test it out, on pavement and gravel.

Do couple different test like, goes fast and slowly stopping, and hard stopping, on both dirt and hardtop. If your rear does lock up very easy, that switch the prop valve to a 40/40 from either an ABS or NO ABS, depending on what your car has.

Alot of people will tell you that you NEED to change the prop exp. when you don't have to, I have read at least 100 different post in diff forums from people that have done the swap and not changed the prop valve.

ABS wasn't an option on any 92 civic models, So make sure everything is Non ABS

Even if the brakes were from an ABS car you just don't use the wires and you're set (except for the MC and maybe prop valve). The prop valve might be an option but the MC is overkill if you keep your stock front brakes. I recommend getting bigger brakes up front and the bigger MC at the same time as a rear disc conversion. It saves you the headache of bleeding the brakes again. Good luck!

Fliptard

If you upgrade your MC, get one from a Teg RS. they are non ABS 15/16 MC and bolt directly up. Prop valve, if you want, or need it later, is a direct bolt up from any 92-95 SI Hatch.

Okay, for the 1 millionth time....

- You only need a larger master cylinder if you change to larger FRONT brakes!!!
Front brake swaps:
- If your installing 16CL-14VN (Civic EX non-abs) FRONT calipers, get a 7/8" MC
- If your installing 17CL-14VN (Civic-abs or Integra) FRONT calipers, get a 15/16" MC
Rear brake swaps:
- If you are only changing to rear discs all you need is the 4040 Integra RS prop valve (not 40/40)

BTW: All Civics with ABS already have rear discs. And the Sedan was the only ABS civic in 92. The Civic coupe didn't even come out till 93, but only had an ABS option on the EX in 94 & 95. The hatchback only had one option for ABS on the Si in 94 only.

ABS was standard on '92 EX sedans, and it was optional on some years of LX sedans.

My car don't have ABS, and the front disc brake is the original from the car, the rear disc brake is original from acura integra 92, and the original master cilinder is 13/16. I need change any way the master cilinder and the promp valve?

Well, I have bled the brakes one last time about a hundred times. The brakes are a little better now, but my rear brakes aren't working at all.

I can see where the pads are starting to actually touch the rotor, and they make a little noise when the brakes are being pushed, but the rear still don't work. After i bled the system, BEFORE i started the car... the rear worked and locked the rotor up, because I had my gf hold the pedal and I could not turn the back, even with assistance from a bar.

My next option is a prop valve, sit seems that w.e valve I have(I haven't looked yet) it's sending alot more pressure to the front than to the back. If it was the MC, it would act the same on all 4 brakes, that's why I'm kinda ruling that one out...

Fliptard

Not intirerly true. If you have a 13/16 MC or upgrade any calipers, you need a bigger MC. If you have a 13/16 and put rear disc on, You need to push alot more fluid into the rear caliper vs, rear drum. A 13/16 will only push enough fluid for so long before it gives out because it's too small.

Only for FRONT calipers.

Your completely wrong. 92-95 Non-ABS Si has rear discs and uses 13/16 MC. 93+ Del Sol Si has rear discs and uses 13/16 MC. Don't believe me, look up the part numbers (I already did). This is why my 94CX w/ stock 9.4" Akebono front discs and Integra 9.4" Nissin rear discs uses stock 13/16 MC and booster and has a nice rock hard pedal (with 4040 prop valve of course). The rear discs need the same amount of fluid as the rear drums.

Are you sure the MC is 15/16"? Almost always, people mistake the 13 for a 15. You need to get really close to tell the difference. There is one on ebay right now that is misrepresented. I also bought one before and it turned out to be 13/16. I was refunded, and got to keep the MC.

A 15/16MC has a big reservoir like this:


A 13/16MC has a small rexervoir like this:


I don't know if the reservoir's can be swapped though...

Anyways, I'll tell you again: If your putting on rear discs, all you need is the prop valve!!!!

94eg! has the right info here.

susy76

Yea sorry you right is 13/16 so which one I need 4040 and how can I Identified if is 4040?

apexi_rsx

even some cars equipted with drum brakes had 40/40 props. from my reading 96-00 all civic had the 40/40 prop valve but the lx and dx sedans.

94eg!

iTrader: (2)

Well, 96-00 Civics didn't have any numbers on their prop valves. But Honda did use the same part number on all 96-00 hatchbacks (rear drums) and 99-00 Si (rear discs). So, yes you could say it's a rear-disc prop valve. I believe rear drum coupes and sedans didn't have that same part number.

It will have 4040 stamped on it at the seam and come from a 94+ Integra RS. The bracket is different though so it fits kind funky (sticks out a little more). And only one bolt hole lines up with your fire-wall. Honda is very specific about not disassembling the prop valve so don't try to swap the brackets.

You could also try the 3040 from a 92-95 Si. It will have the correct bracket and fit a bit better. This is a rear-disc prop valve as well...

94EG8

Not true. '94 - '97 non-ABS Integra prop valves are a direct bolt on in a '92 - '95 Civic, I'm running one right now. You can use a '90 - '93 Integra prop valve as well, but you'll need to swap the bracket. As long as you don't actually let the valve come apart when you remove the two bolts holding it together you should be fine.

The prop valve you want will look like the one shown in the pic. '96 - '00 Civic and '98 - '01 Integra look completely different.

I think you may be right. I thought I had a DC prop valve, but it looks like I may have a DA one. Here are pics I found of exactly what mine looks like installed. You can see only one of the three studs in attached to the bracket. It does bolt up though and is plenty sturdy. I did have to loosen the brackets holding one of the hard-lines to bolt them up, but then it all bolted back down afterward:




This a real 94+ Integra RS non abs prop valve in place:

94EG8

Yep, top 2 are DA prop valves. Here's a pic of my personal '94 RS prop valve in my '93 Si hatch. You really should get the right bracket though, it could vibrate and crack the lines eventually the way it's sitting now.

In Ebay I founded a few 4040 promp valve but I think is to expensive for a used one

iTrader: (2)

There is 10 of them right now on e-bay with the cheapest being $30 shipped.

A 97 acura Integra prop valve fit in 92 civic?

94EG8

Yes, it's the last year that does. '98+ are totally different.

susy76

Baahh All Integra have anti lock
