The knurled knob allows roughly 10 turns of adjustment to cut the rear pressure by roughly 50 percent. The valve is plumbed into the rear brake line to limit rear brake pressure.
Brake Balance Or Brake Bias
How to adjust brake bias. Youll want to have around 60 70 of the braking on the front so adjust the valve clockwise to increase rear brake pressure and counterclockwise to reduce rear brake pressure. If the brakes are still applied as the car turns into the corner the brakebias setting will also have an effect on the cars turnin balance. To adjust the pedal bias it looks like you have to remove the balance bar tightenloosen the cyclinder mounts that connect the pedals to the cylinder push rods then thread the bias bar back through. Brakes rear brake bias adjustment when altering the front brake set up away from the standard installation it invariably alters the amount of rear brake bias needed to re balance the cars brake balance. When the valve is properly adjusted you should have even braking front and rear with neither one locking up before the other. At this point making a brake bias adjustment is as simple as loosening the balance bar locking nut and rotating the bar so that the spherical bearing moves towards whichever master cylinder note that each full turn of the adjustment bar is equal to roughly a four percent change in braking force bias.
The goal is to adjust the proportion of the braking forces between front and rear brake bias in order to maximize overall braking efficiency. Brake bias indicated as a. The brake bias of a car can be affected by aerodynamic elements modifying the center of gravity different piston caliper diameters brake pad friction coefficient brake rotor diameter and many.
