1963-64 Corvettes are equipped with four-wheel drum brakes. These are hydraulically operated, self-adjusting, and feature double-piston wheel cylinders. Three brake options were available with the drum system. Power brakes featured a Moraine vacuum assist master cylinder and were the first power brakes ever offered on the Corvette. The second option was the standard drums (honed to a 20 micro-inch finish and equipped with special heat resistant springs) and metallic linings for more fade resistance. The third option was intended for heavy-duty or competition usage. These cerametallic linings were larger and the drums were finned and scooped.
In 1965, the four-wheel disc brake system was introduced. This system includes a fixed caliper, rotating vented disc, and four-piston pad actuation. A heavy-duty, optional disc brake system was available for special purposes on 1965-75 vehicles. A different front caliper, brake pad, and brake line pressure regulator are used. Heavy-duty brake calipers are easily recognized by the two, pad retaining pins instead of the standard brake's single pin.
