Hi all

Jus did a 5 stud conversion done on an ek non - ABS which had rear drums. I want to change the brake proportioning valve.

Can I use the brake proportioning valve for an ek9 that has ABS?? Or will I have to use a brake proportioning valve from ek9 with non-ABS??

Also if anyone has any pics showing the difference between a non-ABS and ABS brake proportioning valve would help..

u will be able to use one from a car wit abs...i have one in my eg6 that came from an ek9 wit abs an it works fine....there is no real dif i think(correct me if im wrong)the abs jus runs into it thro the hard pipe where as non abs it jus run from it to a fluid distributor an then to the 4 brakes.

I think you mean BRAKE

yeah...spelling police here... :p

I'll wait for blinx to chime in here...as it seems the prop valve on 6th gen hatches in the USDM did not vary and were all of the 4040 variety.

Otherwise, get one from a 99/00 Si/SiR(if you're Canadian)

96-00 civic hatchback in USA have exact same prop valve as 99/00 civic SI (which has front and rear disc almost exactly like integra GSR). now i don't know if the 5-lug setup uses a different prop valve but i would imagine it should be the same as 99/00si wich is the same as 96-00 stock hatchback. Coupe/Sedan may use different prop valves...

Hey Blinx you are one of only a few people that have come forward and said this.
I have been fighting a huge following that said the 99-2000 civic si USA non abs prop valve was special because of rear disc...
But doing my own home work.. have been only able to confirm what you have just said:

Here is the hard facts.... which do not lie
Bottom line says si and dx, hx and civic, 3 door 1996 - 2000
have the same valve

I have called honda USA and confirmed this number.
2000 si 2 door

Camshaft you are correct, i too confirmed with Honda, i learned only after buying a 99SI prop valve, it looked EXACTLY the same so i checked with honda, i even asked how could it be the same if one has disc and one has drum, his explanation was something like this:

"prop valve just balances the amount of fluid going front to back, 96-00hatch dx/cx has small front brakes and drum in rear while 99si has larger front brakes and discs in rear so they end up needing the same balance, its more like a ratio, so if you change just your rear to disc and you have the small front brakes it might be a bit off but if you do the full upgrade to the bigger front discs and add the rear disc you can just keep the stock prop valve."

sorry i am not that good at explaining sometimes.

I know this thread was from a while back, but I'm looking at upgrading my rear drums to discs. Currently an EK 96 coupe with rear drums, replacing with EG rear trailing arms (still 4 lug hubs).

I need a new brake prop valve, but am now unsure about which one having read that bit about it being more of a ratio, distributing fluid between front and rear, I am keeping the front brakes the same, but upgraded to Project Mu SRC 6 slot rotors and Hyper Carbon pads.

Any advice on where I can get a new prop valve (in the UK), I beleive it's a 40/40 I need.....and finally prices?

Thanks

Also if anyone has any EK handbrake cables let me know! :nice:

both blinx9900 and myself are saying is that you don't need one.

If you do your research a north american 2000 si with rear disc has the same prop valve as 96-2000 ek's with drum brakes.
Made no sense to me because everyone was saying you need the 2000si valve.
But if you cross the numbers in the honda parts system.. they don't lie

good luck

hmmmm good info.
i always thought myself that they differ. 99/00 Si to every other trim.
I'm actually in the market for a 40/40 prop valve. but now i'm reconsidering...

what's the theory behind 40/20 prop valves then? is that only when you have drums in the back? So if you convert to disc will it be 40/40???

when you convert to disc in the older gens, you need the 40/40 to maintain balance.

On EF's and EG's you could put in integra prop valves which had on them the number stamps

this is from my post above
Showing you the part number crossing

2000 si has 46210-S04-902
then a civic, 2 door, dx model 1996 - 2000 46210S04902

These are numbers from honda ..
Clearly shows drum and disc have some prop valve
Makes no sense to me

Ok so now I am confused. LOL.

Are you saying this is a 40/40 prop valve. As this looks like the one that was on an ej6 that we did a break conversion on. The brakes worked but there was alot of pedal travel before they worked. We switched it out for a 40/40 prop valve and now have a good solid pedal.
