1990 se/exr rear disc conversion

[sleeper759]

I'm not sure if this is the right section but here goes. I have 90 se that came with drum brakes on the rear. I plan on doing a rear disc conversion this weekend, the local scrap yard has a few 90-92 CB7's. I kinda know that i neen the full rear suspension complete with trailing arms and all and also the ebrake cable. i want to know where on the car is the proportioning valve located and do i need to get one? The parts that i need for this swap, what years CB7's can i get these off of?

I know for a fact that the 92/93 EX comes with disc brakes.


Other's will probably know more.

if you truely had a 91 SE, then it should have came with rear discs.

the prop valve is in the engine bay underneath the brake master cylinder against/ near the firewall.

He's from Canada.
Might be different trim levels up there.

Yo i said tha i have a 1990 se/exr that came with rear drums brakes. not a 91.

Here is what I got when I did my swap:


If you need a break down of everything, let me know.

As for the prop valve, you need a 4040 prop valve off of non ABS car with rear disc brakes.

Here are some pics to help you locate the prop valve (took them when I did my rear swap)

sorry i didn't notice that you're from Canada.

our 91 and 93 SEs down here came with rear discs, which i was trying to pull basically everything you getting also but mine were missing a bunch of parts and it started to rain so i gave up.

He said it was a 1990 se not a 91 is that the same?

[Leung]

i dont really know about the trim levels up in Canada. so i can't comment on that.

The 92-93 EXR (canadian) have the Rear Disc. The EX models DO NOT have disc.

The Canadian EX is a US-LX trim.

As for the prop valve, i have heard of people that didnt use them, and have had no problems.... GL Let us know how it goes.

So i went to the local junk yard and got the whole rear assembly, trailing arms, upper control arms, e-brake cables, brake soft lines,disc and calipers. I could not get out the 17mm bolt for the strut so i took the struts as well. I got alll this for $80 which i think is a good deal. The only thing is that i was told to get the 40/40 proportioning valve from a none ABS CB7 with disc brake, but they all had ABS. Unles there is a way around this i will have to use my stock one. Any ideas on what the best way is to remove the siezed 17 mm bolts from the struts?

[Leung]

the 40/40 prop valve i thought was on an integra?

[sleeper759]

See that i did not know. What year tegi would i have to get this from?

[Leung]

i think you can find them on 94-97 Integra RS.

In the US, the SE only came in 91 and 93, and ALWAYS had rear discs.

In Canada, there might be an SE in 90... and it apparently doesn't have rear discs.


In Canada, only the 92-93 EX-R has rear discs, and maybe whatever the Canadian equivalent to the US SE would be... if they got that car.
