[SETI20]

Tyson on hondatech tried to figure out what those numbers mean, and we're no closer to understanding them.
You would expect the front/rear bias....but no.

You'd have to look the bias up with those numbers you have in the graph he made.
I'll IM him. Maybe he's interested in coming over.

The proportioning valve is a restrictor valve. So I figured it was the restriction percentage.

....but that wasn't it either.
But there IS a big difference between prop valves.
For instance, the EE8 valve I've been planning to install shifts the balance to the rear, because of the increased brake size on the front.
Wich is exactly what I want since I keep locking up my inner cornering wheel.

Because it's not true. Can't put it any simpler than that.

I have tested it out, and I can debunk this claim as fact.

I swapped the proportioning valve out of a civic coupe, with one of a VTi version, and the back/front bias had changed, as was evident on the brake test bench.
Being that it's a friction based test I can't make any statements on the percentages, but the rear brakeing force had increased.
I cannot recall how many points.

 

[SETI20]

Only way I can think of is flow resistance.
Because even the bench braking test wasn't very reliable.
Atleast it produced numbers. Wich is something measurable.
