Hey everyone! I just got a rear disc swap from my local junkyard and from what i've searched i'll need a proportion valve, correct?

I'm not exactly sure where my proportion valve or how it looks, so how easy or hard it is to install/uninstall it. Does anyone have a picture of it??? And with my rear disc swap, i'll need a 90-93 acura integra proportion valve right??? thanks!!!!!!

 

I actually did a rear disc swap and I didnt even use a portioning valve, Ive heard some people say that you should use it, but ive never had any problems.

same here, although I do plan to install the 90-93 teg prop valve. It isn't hard to change unless you have already bled your brakes, as you will need to bleed the system again after installing in.

To find the prop valve, follow the hard brake line down from the master cyl. It has 2 brake lines on one end and one on the other.

Whats does the portioning valve change, I figured id never get one unless there was a good purpose for it

 

disc brakes have the pads in contact all the time with the rotor.
drum brakes have the shoes jsut off the surface of the drum.

a rear drum proportioning valve is set up so that hte rear brakes engage first to take up the slack, then the front brakes engage.
running a rear drum proportioning valve with rear discs means your rear discs are getting too much pressure and will most liekly lock up before the fronts. it also leads to slightly spongey soft braking.

swapping in the 4 wheel disc vavle made a huge difference on my car. pedal travel was reduced, the rubber spongey brakes were gone and becam a lot firmer in feel, and a lot more responsive.

 

not trying to be the weiner but you got most of it correct. the metering valve is responsible for front brake delay and propotioning valve controls rear pressure. most drum systems use a combination valve that has both and most disc systems will use the same setup too. the metering valve will delay the back less in a panic stop since the front brakes are 70 percent of the stopping power the biggest difference between drum and disc valves is the calibration , anyway use the propper valve setup for the application. you dont wnt to sent your mom to the store and have her panic stop in a croswalk and end up plowing over some innocent women and children

 

as far as i know in a honda the proportioning valve is actually a 3 way valve that handles all of that in one package. thats the only reason i didnt mention teh otehr functions needed to properly brake.

 

Ah, well good to know what it actually does, thats pretty much what I thought it did I just thought I might ask.
So I geuss it is worth putting one in. Should I just get one from the 6th gen V6 then?

 

i use the 90-93 teg vavles from a 4 wheel disc car with no abs.

 

What car is teg ? Thanks
