hey i have a 1993 civic 2dr ex that came with drums.....i have gsr front and rear suspension and i wanted to change the prop valve and master cylinder.....i have a 40/40 valve and a 1" master cylinder and booster.....my question is if anybody has a diagram for where the brake lines connect to the prop valve.....thanks

uneek360

doesn't it go the same way as the old one ??

malubawla

my stock prop has 4 lines, the 40/40 valve has 6

Sounds like you might have ABS, if thats true you have to ditch the ABS to go with a 40/40 prop.

malubawla

nah no abs....i have stock rear drums....i need to know how to hook up the lines to the prop valve from my brakes and 1" master cylinder.....someone has to know

Luserkid

Pics will help alot.

pdiggitydogg

that prop you have is for abs
get a non abs prop and you wont have a problem

your new prop valve is probly for abs not sure, u dont need to switch the booster from what i know just the MC

malubawla

i want to use the 1" master cylinder along with the booster and 40/40 prop valve.....i remember seeing a diagram on h-t before, but now i cant find it

i have full gsr suspension but still have the stock prop valve, master cylinder 13/16, and booster

i have the integra parts already, i need help for the brake lines

pdiggitydogg

i wrote the how-to on 1" itr mc/bb swap
and i repeat:
You have an ABS prop, get a non-ABS unit and you wont have this problem

uneek360

yea you need the prop valve from a Teg LS/ GS

so the 40/40 is an abs prop valve......which one do i need then?

if i keep my stock booster and get a 15/16th master from a 91 civic, will i keep my same prop valve?

pdiggitydogg

not all 40/40s are abs...just most
you could use one from an RS, an em1 or ek hatch, del sol si

The prop valve "proportionalizes" the fluid, the MC just pushes the fluid around. Its not like "one has to go with the other" Its just the option.
Really, you can get away with not changing the prop at all (i would/did though)

Hmm good to know...I'm at the stage of redoing my brakes aswell.

I guess I'll look into a RS then.

malubawla

which prop valve did you use......i got the prop valve from a 2001 integra ls, i dont know if it had abs......it has six ports, so i think its abs

Use an RS, they did not come with ABS.

Care to post a pic of a 40/40 prop valve? I did a swap on my del sol S to del sol VTEC brakes all the way around and I dont know if I have a 40/40 or not.

Does the S already have a 40/40?

pdiggitydogg

I beleive its a DA rs valve, actually
try searching for it (going to be difficult since you need at least 3 letters for search though)

edit**
S is not 40/40

honda_racing101

Is a 40/40 really worth getting?

I've searched around the brake conversion threads, but it doesnt say much.

OP: yes for a 15/16th MC you can get it from the 91 honda civic sedan EX. Will bolt right up and all lines will be in the right place.

As far as prop valve I still use the one that came on my 92 cx and have no problems with my 4 wheel disc brakes. It is not neccessary. I hear it gives a little better pedal feel.

My brakes are just fine.

honda_racing101

Opinion wise tho, is it worth getting?
