does anyone know which master clyinder, brake booster and proportioning valve i need for my 93 civic hatch vx for the brakes to brake normally like a type r. thanks

 

I don't think I fully understand your question... are you already 5 lugged? Or just bigger calipers?

If so, you need to start with a 4040 prop valve. The stock prop valve passes more forceto the rear calipers to support the stockdrums, but causes the rears to lock up first in a 4 wheel disk setup.

Next would be to upgrade your master cylinder. The itr runs a 1" mc, but to use it you need to use the matching booster and modify the lines to fit. An easier solution is to use a 15/16" one from a '91 civic ex. Its a direct replacement, bolts up and the lines are in the same place. The difference in pedal feel from the 15/16" to the 1" is very negligible too.

will the 90-91 civic ex 15/16" master cylinder fit my stock 93 civic vx brake booster?

 

so if i went with the 90-91 civic ex 15/16" master cylinder will it fit my stock 93 civic vx brake booster?

does anyone have the part number for the 90-91 civic ex mc?

 

you can also use a 15/16 mc from an integra RS (DA or DC). same lines and same location so no need to bend and flare new line locations.

if you don't mind bending and flaring, the JDM ITR 1" MC has the same size fitting as your civic as well. however, one line is on the other side of the MC unlike our civics where both are further on the driver side.

 

oh yah, here's the part number for the integra MC: 46100-ST7-013

it may have been superceded to a new number now, but your acura dealer will know based on what i've given you.

 

i'm confused now. so the 15/16 integra rs mc one will work also and is it a direct fit. ok so for a direct fit with no flaring or bending i would need a 40/40 prop valve from a 90-93 integra and mc from either the 90-91 civic ex and 90-93, 94-01 integra rs and i use my existing Vx brake booster right. thanks for the help i appreciate it.

you know, i forgot to mention that you would need the matching integra booster as well. sorry dood, i guess it's not a direct bolt-on in that regards.

its cool and thanks for helping so i would need the 90-91 civic ex mc than right since its a direct fit to the brake booster and is also a 15/16. thats what was told and just wanted to clear it up before i start buying the parts.

 

Yep. Thats the exact setup I run, so I can verify it. Your buddie's wrecked itr does not have a prop valve though, since it has abs. You can get it off of pretty much any similar honda with 4 wheel discs and no abs though, i.e. :

94 up Integra RS
92-95 civic/ delsol si
99-00 civic si

I can't remember if the 90-93 integra ones work or not. If its the same shape it should work though, pretty much all of those have the same fittings.

Also, for the master cylinder, I just got a remanned one from Advance auto parts. It was opnly $60 or so and was a rebuilt Nissin anyways. I just put my stock 7/8" one back in the box for the core. That'll save ya a few bucks, a brand new one from hondapartsdeals is $150. Btw the part number for that m/c is 46100-SH4-A11.

hey bro is there a step for installing the master cylinder. is it hard if you can could you tell me how to work on it. i'm trying to save money and rather work on my own car myself. same for the proportioning valve but looks easy to switch. thnks

 

Its all real straightforward.

Read this: http://www.tegger.com/hondafaq....html

Then undo the lines and remove and replace your m/c and prop valve (after you bench bleed the m/c of course).

Now get the car up in the air on four jackstands and pull the wheels off. Then just grab a friend to pump the brake pedal for you and bleed the whole system out to the wheels, moving from rr to lf to lr to rf.

 

so i swapped out my stock vx 3030 proportioning valve with a 90-93 integra 4040 proportioning valve and is was pretty tough to break those dam flare nut loose but i got the job done tighten everying up and i'm still using my 13/16 MC and haven't bleeded my brake yet. does anyone one know if i have to bleed the brakes cause my brakes feels the same as if i was using the 3030 prop valve. i know the MC also make a major different too but i'm doing it one step at a time. will be ordering a 15/16 MC pretty soon just waiting for the funds. so if i bleeded my brakes the way it is now will it be any better thanks for all the help

Yes, you need to bleed the lines since you replaced your prop valve.

 

ok i'm gonna try and bleed it tomorrow thanks
