In this picture, why two brake bias valves on single line? What is the advantage? Coarse and fine adjustment, out of single valve range, who knows?

 

Wondering the same thing....

 

ditto....

 

I think his brake line was about an inch too short, and he used the second valve to make up the length.

 

And who's the driver - Stretch Armstrong?

so when people look at it, they can ask:
"why two brake bias valves on single line."

 

I am guessing it is in case one fails....

 

One looks to be near the max (or min?) and the other is at the limit. I suspect they are in series for finer control ie: 0-100% control of the one limited to say 20%. It looks like the dash says "Realtime", so I would guess they know what they are doing. I agree about the Streach Armstrong" driving position. I don't think I could even see the pedals from back there.

 

I have never run a brake bias adjuster but will pretty soon. Jim Leithauser used to run a lever adjuster and a **** adjuster in line saying the rear brakes when switched to their own circuit from the factory X patern needed quite a bit of restriction. He said the **** was for getting him in the ballpark then actually used the lever to adjust when driving. His point was the lever had specific detent notches for reference points and could be adjusted without really looking at it however the **** style couldn't really be adjusted well to a specific spotm on the fly as it had not point of reference.

The ones pictured are far enough forward that I can't see a belted driver adjusting them by hand but a dexterous foot motion could probably tweak it (although I doubt the Realtime guys have their right foot off the throttle that long).

 

I guess Kleinubing doesn’t have two long right arms!
