This brass proportioning valve for front disc and rear drum brakes adds safety to your brake system.
It is wise to add a proportioning valve equipped with a safety switch when upgrading to a dual bowl master cylinder.
The safety switch built into this valve senses when unequal or lower pressure is produced in your brake system, usually due to a component failure.
When the valve detects a drop or change in pressure, it cuts off the pressure to the port supplying fluid to the defective brakes, thus stopping the leak.
You may notice a change in your pedal feel, your brakes' stopping ability, and possibly the warning light on your dashboard.
You can safely pull the vehicle off the road without causing harm to yourself or your vehicle.
Without this valve, if a component fails, your brake pedal may drop to the floor as you pump it with little to no braking.
Brakes are the most important component on your vehicle, so do it right the first time and be safe.
