I know a proportioning valve controls/limits the amount of fluid that can pass through. Therefore allowing you to change braking bias front to rear.

I notice that some people use them, while many do not. What are the pros and cons?

I run a prop valve inline behind my inline hydro, just because that's the only place it would plumb in with my existing lines. Definitely will change the power your hydro has, but in my case I still have more than enough - if you were happy with the bias during normal braking and wanted more power with the hydro, step up a MC size on the hydro.

Sure will.

The issue I am having is that when just cruising the hydro has little to no effort, as soon as you tap the brakes and pull the hand it locks the wheels up no problem.

I have STI brembo calipers and am using a 3/4" master cylinder.

I have bled it per the procedure on here, as well as bled it using a power bleeder and am confident that air in the system is not the issue.

So maybe I need a different master cylinder?

Just intalled my PBM inline with Wilwood MC and line kit, and it locks the rears instantly.

It all comes down to bleeding it properly. I highly recomend trying to find access to a air compressor and pressure bleeder, makes the whole process effortless. I am also running Project MU rear pads, which are worth the investment.

My ASD handle is really stiff maybe 2 inches of pull that's it. Doesn't lock at all has any one experience this?

pass through

I did an inline. I keep getting air out of the passenger rear caliper only. Brakes and handle are soft.

My PBM Inline is stiff as well, probably close to 2" too, but locks perfectly.

Bought an asd reveres pull hydro e brake, with 5/8 master which is what asd recommends for stock s13 calipers and am running -3an lines from fromt master cylinder to rear brake and hydro pulls back maybe 2 inches but basically doesn't lock the rear wheels at all, hydro feels like almost too stiff like something is blocking the lines but nothing seems to be in the lines. Any ideas?
