So far I understand that it regulates the amount of brake fluid distributed between the front and rear disc brakes. Do cars with rear drums have or need prop. valves?
Thanks

 

yes

 

Okay cool, so say I want to upgrade my 9.5" 93 civic front brakes to 10.3" teg GSR front brakes. I do however plan on leaving the rear drums alone, it just doesn't seem worth the upgrade to me considering they only do about 10-20% of total braking. Anyways, I'll add a 94 teg RS master cylinder and booster at the same time. Which proportioning valve should I be using?
Thanks again

 

you should probably use the existing prop valve

 

from what i have heard if you don't plan on changing the back brake to disc then don't change the valve. if you change the back to disc then get a 4040 valve. otherwise leave it alone. and yes it is a very good idea to upgrade the mc and booster because the GSR calipers will need alot more fluid to get them to compress. just my .02 and you know i have the mc and booster if you need. thanks

 

Sounds good, Thanks alot guys

 

I'm doing upgrade all the way around (96 spec ITR) and the guy at the shop said he reccomends upgrading to an integra MC and the proportioning valve, even though the fronts do so much more braking the front calipers running the old valve will send the front end down when you brake. I'll just take his word though.

 

i think all of them are the same

60% FRONT 40% REAR

pretty common on most cars

right?

but wait!
if you have rear drums i know that the drum brakes get fluid before the front disks....cuz there is a delay in activating drum brakes.....with 4 wheel disk, all four brakes grab at the same time

I guess thats not a bad thing. Since my rears are gonna be so weak, maybe its good they grab first so I don't endo
