After years of developing unique brake products, Classic
Performance has developed their most innovative product yet. The all NEW
MCPV-1 which combines 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. The MCPV-1 is the
master cylinder, proportioning valve, metering valve and stop light all
in one package. The unique shape allows it be located on the firewall, under
dash or on the frame just about anywhere. Its approximately the same
size as the ever-popular Corvette master cylinder...only 260% 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.
