ok, so im doing a rear disc swap on my 89 crx si. i have a 90 crx si, and today i pulled everything off that i need, except for the proportioning valve:the bolts were rusted on.
Ive read all over here, that some people have done fine without the 5050 prop valve. and I was just wondering is this ok to do, or do I absolutely need the prop valve?
Im thinking that i really will need it, because thats the right valve for the discs, thats what honda intended so it must be right, but just wanted to see, maybe i can shortcut/save some time.
there was no clear answer anywhere, so just wanted to get it straight before i go back with a hacksaw and wd40.

 

what breaks will you use?

integra/eg civic (or any upgraged) front + si/teg rear = 4040

si stock front + si/teg rear = 2040

 

im using stock 89 crx si front brakes. and 90 crx si rear discs.
so should i pull the prop valve from the 90 crx si? or just leave my stock one on?

 

imo, id pull the one off the 90, cause your prop valve was installed for drums, and the other one is make for disk brakes...

 

wen i did my rear disk swap i didnt replace the stock prop valve (25/30) till like a couple months later with the 40/40...

its recommended to swap it out wen u do the rear disc brake swap because it evens out the braking in da front and rear
