I'm once again upgrading the brakes on my Omni GLH Turbo. I did have a complete braking system from my Shelby Lancer, including the rear disc setup and proportioning valve. I'm now upgrading to SLH III, which consists of Caravan front brakes and 11" vented rears from a '91 GTC. Should I use the prop valve from the '91 GTC or stick with the prop valve from the SL?

BTW...My car already has the 24mm master cylinder, which I will continue to use with the SLH III stuff.

Try the one you have in there from the SL, may be fine
with your cars weight. Switching to the newer one will
give even more pressure to rears. I am actualy thinking
of doing the opposite, removing my later big rotor rear
disc prop for an older disc prop. My light rear end gets
away under real agressive braking in corners since recent
weight mods.

Thanks Russ! Nice to hear some real world experience about this.

When set up correct the big brakes on these cars will give you
a smile almost as big as 20+ psi of boost, keep on it. Not kidding
when I say I could not wipe the smile off my face after first hard
braking, had replaced the mint stock GLHT brakes that work perfect
but man I never knew how fun stopping could be...just watch the
late model cars behind you closely when using the SLH package

I thought i would post here since russ has brought up somthing that i wondered myself. sorry to hijack your post but it's right on subject.

wich prop valves are you refering to russ?

i have the vented rears along with the prop valve from the same setup, after watching some old racing vids when i was driving my csx. the rear would come out in hard corners while braking hard. so that gave me the same idea you mentioned of changing the prop valve to lower the rear pressure. since mt omni that has the larger brakes and it is a lighter car i thought this would be a good idea. but i am not sure on wich prop valve to try. -Dave

The vented rear rotor cars have different valves than the
solid rear rotor cars, as you have. My setup was from a 94
v-6 Daytona with all the wistels. The setup was great until
I removed a lot of weight from rear of my car, noticed rear
kickout under hard braking in corners. With tires hot and good
surface its fine, just damp or cool days its noticable for me.
