This booster works with a 70's style cast iron master cylinder, it will not work with the plastic step down masters found on Camaros after 1980.
This includes a Cast Iron power master cylinder These master cylinders feature a 1" bore, and 9/16" and 1/2" ports. These are brand new dual resevoir cast iron master cylinders.
Also included is a disc/disc 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. Should you opt to do the install yourself, ALWAYS follow the manufacturer's service and install directions carefully to avoid damage to yourself, your car or its components.
