LEED Brakes PV2_B Proportioning Valve Disc Drum Brass SKU: LEEPV2_B Leed Brakes proportioning valves ensure the correct brake pressure is provided to each wheel for safe, controlled stops. Available in fixed or adjustable and a variety of finishes, we have the correct valve to complete your installation. Add safety to your brake system with this front disc/ rear drum brass proportioning valve. When upgrading to a dual bowl master cylinder, it is always wise to add a proportioning valve equipped with a safety switch. The safety switch built into this drum brake brass proportioning valve senses when your brake system is producing unequal or lower pressure to one or more of the wheels, usually caused by a component failure. When the valve senses this drop or change in pressure, it will cut off the pressure to the port supplying fluid to the defective brakes, thus stopping the leak. At this point, you have noticed a change in your pedal feel, your braking ability, and possibly the warning light on your dashboard. You will now be able to safely pull the vehicle off the road without causing harm to you or your vehicle. Without this valve installed, if a component fails on your vehicle, your brake pedal will drop to the floor as you pump the pedal with little to no braking. Brakes are the most important component on your vehicle; do it right the first time, be safe. Application Summary: UNIVERSAL
