The bracket and line setup is designed to mount the valve to the left side (driver's side) of the master cylinder. These functions include the following:Proportioning: As more force is applied to the brakes and the car begins to lean forward, less braking force is needed in the rear. This valve decreases the pressure to the rear, preventing lock up.Metering: Metering is used in the front disk brake portion in the disc/drum system to delay application of the front discs allowing the slower reacting drum brakes to catch up. This provides rear stability on wet surfaces and helps prevent front pad wear. There is no metering function with the disc/disc setup. System Failure Switch: This valve has a system failure switch that will alert you when half of your braking system is not working properly. These proportioning valves usually list for $100+ alone, you're getting the whole kit here for less! This is a must for any disc brake conversion.
