'96-EJ6Hatch

I saw a thread on an ek rear disc swap, but i couldn't get one question answered. I'm Doin' it to my 96 dx hatch, I know it seems redundant for me to ask since since there's already a thread on this, but i need to be sure. If i use integra trailing arms, i know i need integra rear brake lines, but do the MC, Prop valve, and e-brake lines have to be integra too? or do the 99 Si MC, prop valve, and e-brake lines work with the integra trailing arm and brake set-up? Any help would be most definitely appreciated by a fellow EK lover.

E brake lines yes. Mc/prop vavle no.

So i can use the Si MC, and Prop valve?

'96-EJ6Hatch

Sorry if i seem stupid I just want to get this stuff right before I go buying parts lol.

You don't need to change the mc or the prop valve.

98civdx

No you don't.

Only change the MC when upgrading the front brakes.

The Si e-brake cable will def. work - don't know about the teg. The DX cable is too short.

The Si cable is cheap even from a dealer.

I'm changing the back brakes from drums to discs. I KNOW i at least had to change prop valves cause drum brakes have use a higher pressure rate than disc and leaving the old one in could cause the calipers on the discs to not fully let go. But do I need to change the MC too? I don't think I do... And will the Si prop valve work with my tegi trailing arms/brake lines etc....??? And i was pretty sure about the e-brake cables..

I did the swap on my 97, and i had to change the prop valve to the si one. works fine now.

'96-EJ6Hatch

Cool, so it looks like im gunna use the integra trailing arms assemblies with integra rear brake lines, and si e-brake cables, si MC, and si prop valve.. any body see any problems with that? otherwise I'm set I'm gettin set to start workin' as soon as i get the Prop valve and MC. Probably gunna make a thread for my build.

Did you even read my posts?
YOU DON'T EVEN HAVE TO TOUCH THE MC OTHER TO ADD FUILD!!

Notice the part numbers I bolded.

You DO NOT have to change either! The only reason to change the MC is when you are adding larger front brakes!

'96-EJ6Hatch

Yes, I did read what you wrote. But from what I've read in other threads, you have to change at least the proportioning valve because the one from the DX has a higher pressure for the back brakes to accommodate the drums. I've heard that if you don't change the Prop valve and MC that the pressure will be too high and the rear discs won't fully open. Is that not true? I read it in this article:
https://honda-tech.com/forums/showth...=641639&page=4
And yes, I do have an EJ6. It came stock with drum brakes..

'96-EJ6Hatch

I'm guessing your brakes wouldn't let go before you changed it?

98civdx

No, it's wrong.

look at the part number for the SI, and then the number for the DX.

They are only listed for 2000, but they are the same for 96-00


You will see no gain if you swap the prop valves. I am speaking from personal experience when I say this.

'96-EJ6Hatch

I know the part number is the same, that, and many other articles said the part numbers are all the same, but they still have different pressures and the ones in the SI's and EX's are the only ones that don't have to be changed. But according to you, I should be able to hook up my tegi trailing arms, with the tegi rear brake lines and SI e-brake cables, and call it a done deal? I guess if it doesn't work I know what to change lol Thanks, this may have made my life much easier.. And i didn't think I'd gain anything, just wanted to avoid having my brakes locked and having to do it later lol

98civdx

No. based on the part numbers the EX is not the same. The EX/SI share the same MC, and front brakes. But, we did use the orginal prop valve in my buddies EX with no issues.

Yes, that is all you need. I've done it a few cars, aswell as quite a few of my friends.

Use 99-00 SI E-brake lines, generally you want to use the brake line for the caliper you have.

'96-EJ6Hatch

The guy in the article even said hes gotten away with not doing it in some of his friends civics which makes me think its just discrepancies in the prop valves form car to car and just needs to be checked after the swap....

'96-EJ6Hatch

Yea i know, i was told i needed the Tegi rear brake lines to match the caliper attachment, but the SI e-brake lines will fit, saving me the trouble of choppin the tegi ones up. Thanks man!!! you helped alot!! sorry if i seem stupid, i just like to have the RIGHT info before i start workin or buying parts. Don't need to pay for an MC/Prop valve i dont need!! lol

98civdx

A lot of the time someone will say you need to swap it, beucase it's what they read. Not experienced.


I know how it is, trust me. I do the same thing before I do something. I am actually getting ready to either so SI brakes, or ITR's in my car. lol

jbpnoman

Rear disc swapped EJ6 right here. Didn't swap the prop valve. Brake pressure is fine. You don't need to replace the prop or BMC.

'96-EJ6Hatch

Cool!! Thanks Guys!! I got the Trailing arms today and they're in great shape!! I can't wait to put'em in I'm Itchin' to get at it. Now that I don't need the MC or Prop Valve I can start sooner. Even though the guy gave me MC and Prop valve with it lol. Got it all for $100!!!

98civdx

Check/replace the trailing arm bushings before you install them

teaks92hb

On my LX I had not changed it before doing the brake swap, and my brakes kept sticking. Once I changed the prop valve everything worked. I also read about the different pressures and people running into the issue with the rears sticking. So I went with the SI one and I'm happy. This was just my experience though.

'96-EJ6Hatch

Yea I planned on that. Also gunna grease the **** outta everything lol

Thanks man, if i end up needing it i have a new one so I'm good. Gunna swap'em and see if the old one works lol
