Classic Performance residual check valves are required in a brake set-up that uses an adjustable proportioning valve. A check valve is run inline on the rear brakes in disc/drum systems to ensure the shoes stay in contact with the drums. Failure to use a residual check valve will allow the brake springs in a drum system to compress the wheel cylinders, resulting in excessive pedal travel. These fittings are available in a variety of sizes, PSI pressure ratings, and finishes.

After years of developing unique brake products, Classic Performance has developed their most innovative product yet. These MCPV-1 master cylinders which combine the master cylinder, double adjustable proportioning valve, removable metering valve and stop light control all in one compact light weight unit, available for Disc/Drum or Disc/Disc applications. The MCPV-1 solves many problems associated with trying to do the same thing with four or five separate pieces being plumed together. Their unique shape allows them be located on the firewall, under dash or on the frame just about anywhere. They are approximately the same size as the ever-popular Corvette master cylinder...only 260 percent lighter. The MCPV-1 has two circuits...front and rear. The front circuit of the MCPV-1 contains the metering valve, which is required on cars that have disc brakes on the front wheels and drum brakes on the rear wheels. The metering valve does not allow any pressure to the disc brakes until a threshold pressure has been reached. The threshold pressure is low compared to the maximum pressure in the braking system, so the drum brakes just barely engage before the disc brakes kick in. Having the rear brakes engage before the front brakes provides a lot more stability during braking. Applying the rear brakes first helps keep the car in a straight line. The rear circuit of the MCPV-1 contains the adjustable proportioning valve and the maximum rear pressure adjustment. The adjustable proportioning valve controls the balance of pressure between the front and rear brakes. For example, if the adjustable proportioning valve was set to 70 percent and the brake pressure was 1000psi, the front brake would get 1000psi and the rear brakes would get 700psi, regardless of what type of brakes a car has. The Maximum Rear Pressure Adjustment controls the maximum rear pressure allowed to the rear brakes to help prevent rear wheel lock up. If the Max Rear Pressure Adjustment is set to 500psi and the adjustable valve set at 70 percent, the front brakes get 30 percent more until the rear reaches 500psi.
