what do the numbers mean, %, psi, I should know this by now

anyone?

 

NOBODY knows!

I've asked all over the place and other than some engineer in Japan, the information just isn't out there!!!!!

It's not a ratio, or the 30/30 valve would be the same thing.

Maybe it is psi then.... since the rear disks are smaller (if drums, takes more pressure to work) that might be the answer. All I know is that with my stock prop valve my rear itr disks lock before my front itr disks. I'm thinking about getting a 99/00 civic si prop valve...I wonder if that will do the trick...

anyone have anymore input?

Its usually the brake bias between front to rear. Like 70/30 is 70 percent of the braking is done by the front & 30 is done by the rear.
