I've been searching through the posts for a couple hours now, and can't find a definite answer... I think I find one, and then someone argues against it... so I figured I'll just ask..

I'm about to switch to a disc rear.. what's the difference in pressure? will the rear discs lock up quicker if I don't get a disc brake prop valve? or will they not get enough pressure? can I just get an adjustable prop valve or do I need the GM disc brake valve?

I don't really want any "I think it's this way" or "maybe" or anything... that's all I've been finding when searching through posts... I want definite answers, dammit!

Thanks.

 

I know I was this close to running the drum pro/valve when I initally switched rears, but buddy had a disc prop. valve so I stuck it on. Tell ya later this week if it'll work with a drum rear since I blew the other disc rear to bits.
