New 7" dual booster with master cylinder and proportioning valve kit.  This setup is used for disc/drum brakes.  A setup like this can easily cost you over $350, so the deal is here.  These are often used under the floor of street rods and hot rods.  The 7" dual booster offers 27% better stopping power over 7" single boosters, making this setup much better for increased safety on your vehicle.  These is the best deal you'll find on a quality setup like this.

The master cylinder is a Corvette style master cylinder with a 1" bore.  Also included is a disc/drum proportioning valve kit (self adjusting valve  and bracket to mount kit to the side of the master cylinder).

The proportioning valve has a zinc finish.  This valve is also call a combination valve, as it performs all of the necessary valving functions with a disc brake conversion.  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.

  • Residual Pressure:

Drum Brakes require residual pressure of 10 lbs. to be held in the line.  This pressure keeps the brake shoes close to the drums giving you a more firm pedal feel.  The disc/disc setup does not require this pressure.

  • System Failure Switch:

This valve has a system failure switch that will alert you when half of your braking system is not working properly.

As with any brake job, professional installation is recommended, as it is vital that everything is installed correctly prior to use.  Thanks and good luck!!
