Single To Dual Master Cylinder Conversion + Manual To Power Brake Conversion: One Master Cylinder Kit

For decades we trusted single-reservoir master cylinders on our daily drivers and our street rods. But, the thought of evacuating all of your brake fluid due to an aging or faulty wheel cylinder, brake hose, or brake line issue is frightening. Our 1964 Chevelle was built toward the end of the single-reservoir era. Dual-reservoir master cylinders would become the industry standard just a few years later. The same principles apply to many popular platforms, such as the Tri-Five Chevy and most cars or trucks built before 1967.

Removing old master before installing CPP Master Cylinder Kit for '64 Chevelle

The braking system on our Chevelle project car never gave us any signs of failure. But, for safety purposes, we decided to proactively upgrade our master cylinder.

The Solution: CPP Master Cylinder Kit

Classic Performance Products (CPP) offers a kit that not only converts the car to a dual master cylinder, but also converts it to power brakes. The brake booster offsets the increased pedal effort from the larger bore inside the master cylinder.

We used CPP’s master cylinder kit (PN: 6474BB2). The kit is a direct bolt-on for cars using disc brakes up front and drums out back. The master cylinder kit includes a cadmium-plated brake booster and brackets for bolting directly to your stock firewall. It also comes with a new dual-reservoir master cylinder, pedal pushrod and clevis. It even ships with pre-bent hard lines, proportioning valve and bracket assembly. One additional item that makes this installation easier is a new hard brake line kit.

In the case of our Chevelle, we used a Right Stuff kit from Summit Racing (PN COP64H2). This works for 1964-1967 Chevelles with power disc brake conversions. Overall, our brake booster and master cylinder upgrade only took a few hours (most of which was spent installing the new lines). It also set us back about $400, but that’s including the new brake lines and brake fluid.

We’re looking forward to the added confidence and comfort when it’s time to slide behind the wheel of our weekend cruiser.
