I'm planning on going to the junkyard this coming weekend, and I'm planning on doing a rear disc brake conversion on my 90 civic Si... So can you guys give me some info about this project?

Thanks..

 

Hey buddy what discs are you going for the Integra or CRX si? I think I am going for the CRX si in a couple weeks

 

This is funny we are on the same situation .. I dont know man, if the CRX Si is direct bolt-on then I'm going on that route. I didn't knew until you told me that CRX Si came with a rear disc brake.. BTW, what is the difference between the teg and rex disc brake?

C'mon guys need more feedbacks...

 

You need to get the rear disks & control arms...etc from a 88-91 CRX Si. Then you need to get ebrake cables off a 90-93 Integra ~if your puting them on the civic because the crx cables are too short~ Then u need to get the master cylinder and break booster off a 88-91 CRX Si or 90-93 Integra preferably the Integra. (I have heard that the brake booster and master cylinder is not neccissary, but i would recomend it. Also make sure u get the master cylinder off an Integra that does NOT have ABS. The fittings for the brake lines don't match up on the ones that do have ABS. And thats it for parts i think...if i think of anything else i'll post it up. If you want procedure steps send me an email at: abel_b21@hotmail.com.
I would be happy to help...I just did this swap a few weeks ago so I still remember what i did

Good luck

Rather than changing out the booster just pick up a 90-91 EX master cylinder. You will also want to grab the Si proportioning valve. There has also been some talk of the integra trailing arms giving a you a slightly wider track. Not real sure about that though. I went with the rear set up off of a 90 Si.

 

I picked up the rear knees from a teg, I hope it works. I thought the trailing arm and brake assembly was all I need and it would work (plus the ebrake cable and ex MC). I'm not gonna be able to get to it for a while I dont think, they've already been sitting in the garage for 2 months.

 

All you need is the rear trailing arms from a 91 Teg, and the e-brake cables from the same car because they are a little longer, which you will need. Everything should bolt right up to your existing set-up. You will probably want to replace your brake lines in the rear, depending on their condition. You do NOT need control arms, knuckles or any of the other components. My conversion is great.
The only thing I would reccomend as a " nice to have" is the master cylinder and proportioning valve of the same car for extra oomph!!! when stepping on the brakes.

Good Luck !!

 

You absolutely need the hydraulic brake lines from the disc car. The fittings on the drum brake lines are different.

 

not true.!

 

Guiseppe: Care to explain?

 

the hard line from the drum brakes
to the newly installed 90-93 teg rear trailing arms is the
exact length, and it plumbs up perfectly.

the only reason youd need new lines is if the 4G ones break
while you're disconnecting the brake line connections..

i did the rear disk without a hitch.! and i love the mod.

 

I would buy re-man calipers as well. From a place like Autozone or Pep-Boys.

 

let me get this straight..too much conflicting info on here...

find a 90-91 teg..
get the rear trailing arms, brake assembly, brake lines, e-brake cables, master cylinder, and porportioning valve. install that stuff on my civic.

how much should this stuff cost at a yard? are those the only years that the teg stuff will work? thanks in advance..

 

Thanks guys...

 

Hell, I'm in the same boat. I have a four door EX ('91) and I have the rear trailing arms off of a CRX Si. I have the four door Acura cables, and I was told that I would need the proportioning valve from a 90-93 Integra to make it all work out OK (NOT ABS). That rear arm supposedly bolts right up. I have front bushings on the way from Energy Suspension and I have powdercoated the arms.

 

1. find a 90-93 teg.
2. this is what i took... rear trailing arms with the rotors and calipers
attached, (just to drive around temporarily,they were replaced later)
3. ebrake cable, take the clips too!!!
4. prop valve 4040
5. master cylinder 15/16
6. booster...

 

Bought 91 Teg left and right rear brake assembly(control arms etc...)...used brake lines that came w/ it along with the e-brake cable, just replaced the pads and rotors. Spent $75 bucks on the assembly, plus an extra $150 for 2 powerstop cross-drilled rotors and oem pads. Total: $225 plus $10 for bottle of good brake fluid.

 

thanks guys !!

 

Giuseppe: I am referring to the rubber hydraulic lines that attach to the caliper. The fitting on the end of these, where it attaches to the caliper is a banjo fitting, whereas the rubber line on the drum equipped car is flare on both ends and obviously much too short.

 

OK... on my '91 EX, should I pick up a '90-'93 Integra master cylinder? Bolts right up, right?

 

Just keep you stock EX master cylinder. It is the same size (15/16) as the integra.

 

Sweet... after the cables/calipers/trailing arms/rotors/bushings/powdercoating, I didn't want to spend anymore $$$.

Thanks.

 

yes this is correct,
i thought u were refering to the 4G hydraulic hard lines..
