How can i tell if my proportioning valve is a 40/40 valve.....is it stamped on it...??? if so, i think my civic coupe already has it.........and i have rear drums.......swapping tomorrow to disc, hopefully....

 

If it's an EG, it will have it stamped on it. I highly doubt your coupe has a 4040 prop valve.

My stock one was 3035.

 

i have an EJ1......the coupe........will it be stamped on it?......previous owner may have had a prop valve go bad or misdiagnosed something, and put the 40/40 on it.....

 

bump to see if it's stamped 4040 on my prop valve.....


restating the question:
I have an 1994 EJ1, will my prop valve have 4040 stamped on it if it is a 4040 valve?

 

went out and looked, to check myself....did a littel searching on here, i have a 3030 prop valve......how will my car brake with this valve, as for rear locking up before front?......better or worse? anyways, im looking for some real responses, besides, it'll brake like crap....explain to me what will happen....

 

i kinda need a response asap, if possible......lol

 

well if you lock the rear before the front, ur gonna end up sideways when u brake hard. Just find out what prop valve your car came with, seach the classifieds and buy one.

 

I have a 92 cx with gsr front and rear brakes. Stock M/C and rear prop valve. Pedal goes down a little lower but braking is tight and consistent, only locks up when I really press on them. You will have no problems.

A Master Cylinder from a 91 civic sedan ex which is 15/16 will bolt right up no problems and a 3040 rear prop valve seems to be the right choice with rear discs on these setups. You can go 4040 prop valve but I personally feel that is a little much. Or you could go adjustable rear valve.

This is what I am going and have heard good results with better pedal feel on these setups.

Good luck.

 

i just did the swap this weekend let me know if you change the master cylinder or the proportioning valve because i didn't and i think it does fine.

 

Mine does to but I know there could be a little stiffer feel there with a 1/8 bigger master cylinder.
