1966 Corvette Brakes
Second-generation Corvettes saw several master cylinder styles. Model years 1963 through 1966 had a single-line system. These had a master cylinder where the front and rear brakes operate from one brake line, so if a leak occurred or the master cylinder failed, you would lose ALL your braking ability. In 1967, GM replaced this brake system with a safer, two-line master cylinder.
One non-stock upgrade to the 1966 Corvette restoration is replacing the original single-reservoir master cylinder with a dual-reservoir master cylinder. This has become a popular choice with owners of 1963-66 Corvettes who wish to upgrade to the safer, 1967-style dual reservoir master cylinder.
Replace, Rebuild, or Re-sleeve Your Master Cylinder?
New, good quality (not cheap Chinese) master cylinders are expensive. If yours is not badly pitted, consider rebuilding it. Rebuilding a brake master cylinder is not difficult and doesn't require any special tools. If your classic Corvette will see less than a few thousand miles a year, a rebuilt master could last five or so years before pitting becomes bad enough to damage up the rubber.
If your master cylinder is badly pitted, consider sending it out to be re-sleeved. Some companies will re-sleeve with brass, others prefer stainless.
C2 Corvette Calipers
Patterned after the Grand Sport Corvette race cars of the early sixties, four-wheel disc brakes were found on 1965 through 1982 Corvettes (although some early '65 models were sold with drum brakes). Although original C2 and C3 piston bores were cast iron, most Corvette calipers have already been stainless-steel sleeved somewhere in their history. This is easily told by the shiny smooth silver circle inserts that the pistons sit in. If they are still the original cast bore, consider having yours stainless-steel sleeved. Most Corvette suppliers offer this service.

Seems like C2/C3 Corvette owners who have switched to o-ring caliper seals report improvement. But if they're comparing fresh rebuilt o-ring calipers to old and worn lip-seal calipers, that comparison isn't really fair.

C2 Corvette Brake Rotors
The reason for those hub rivets was for the factory to have an easy means to install the brake rotors. They were then trued as a hub and rotor unit so that there was no run-out. Once the rotor is removed, it's not necessary to replace the rivets. The Corvette service manual recommends using the lug nuts of the wheel to hold the new rotor in place. When the wheel nuts get tightened down, it will center the new rotor on the old hub.
