Thereof, How does a adjustable proportioning valve work?
Nearly every adjustable proportioning valve on the market today has an adjustable knee point (the point at which the rear brake line pressure begins to be controlled), but a fixed slope (the rate at which it builds beyond the knee point). While one parameter is adjustable, both are critical to system performance.

Proportioning Valve Adjustment: The proportioning valve is used to adjust the rate of increase in rear brake line pressure, relative and proportionate to the increase in front brake line pressure. For safety and performance, the rear brakes should never lock before the front brakes.
Can you bypass a brake proportioning valve?
Re: To bypass or not to bypass proportioning valve? Yes, do it.
How do you use a brake proportioning valve?
You’ll 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. When the Valve is properly adjusted you should have even braking front and rear with neither one locking up before the other.
Where do you mount a proportioning valve?
The proportioning valve is mounted between the brake line master cylinder and the rear wheels. It’s designed to adjust the pressure between the front and rear brakes, depending on how hard you’re stopping. The shorter the stopping distance, the more of the vehicle’s weight is transferred to the front wheels.

What happens when a brake proportioning valve fails?
Since the proportioning valve decreases the pressure sent to the rear brakes, the main symptom the valve is going bad is the rear wheels locking up when the brakes are applied. Furthermore, the wheels will lock up more easily on wet surfaces. The rear brakes may feel touchy when applied even gently.
