Hi,
MattCSLnut- A rear in line Brake bias valve will
increase or reduce the amount of rear Brake.
Most cars are around 70% front 30 % rear.
When you fit a Bigger Brake to the front
this ratio can alter to say something like
75% front 25% rear.
You would not really notice this in normal
driving conditions.
Bigger brakes do not dramatically alter the
brake grip or bite, but they do increase the
their ability to maintain the brake pressure over much
longer repeated periods. Much less fade
Come the rain though, and you would need
to restore the original front / rear brake ratio
and even increase it in really wet conditions,
by having more rear bias.
Something like 65% front 35% rear.
So by having the bias valve in line for the rear
allows you to compensate for the changes.

The Gorilla.
