Speedway Tech Talk - CPP Hydroboost Brake Systems


Speedway Motors employee Pat is back to cover the CPP Hydroboost Brake System.

If you’re running a big motor and cam combo, and you’re having issues with vacuum supply for your standard power brakes, these are a great option to consider. These systems put out close to 1800 pounds of pressure at the wheel cylinders, which should be more than adequate for your needs.

Pat brought a couple systems out to look over, the first being built for a 62-74 Chevelle/El Camino, 67-69 Camaro, and 68-74 Nova. It features the 4-bolt mount pattern with the 3-3/8” spread between bolts. The second system that Pat brought out is similar to the first, but it is built to be a little more universal. The second unit is a 2-bolt mount, with a 3-3/8” minimum spread, and the ability to spread up to about 3-1/2”.

Both units use a Corvette-style master cylinder, as well as an adjustable proportioning valve. The shiny chrome system has a built in pressure brake switch on the proportioning valve, where the plain system does not. The plain system is built to accept a switch though; the port is just plugged with an Allen head screw.

The CPP systems measure about 22 inches in length, so they are considerably longer than a traditional dual power brake system. That may pose clearance issues for some builds.
