Disc Brakes for the Corvette Stingray C2

1965 is an important year for Corvette. A long desired and needed upgrade - disc brakes - became standard equipment and for years to come would be the only American car so equipped. The good news is that they appeared on all four corners, not just the front as was common practice of the day. Racers were particularly happy with this latest development as they had long been suffering with drum brakes. Although special sintered metallic linings had been available, fade under racing conditions was still a problem. Jaguar had been offering four wheel disc brakes on their more expensive E-Type and it wouldn't do for the Corvette Stingray to be playing second in any area. The unloved drum brakes were still available as a deletion credit (RPO J61, -$64.50) and 316 1965 Corvette Stingrays were so equipped.

Above left is the front Corvette C2 disk brake, right is the rear Corvette C2 disk brake. The rear disk brake also incorporated the parking brake which was actually a conventional drum brake. The parking (or emergency brake) was a problem in the development of early disk brake systems so a drum system was the solution.

Right: GM was proud of their 1965 disk brake upgrade and let the world know about it in their marketing efforts.

It is a fascinating scientific / engineering look at how and why disc brakes came to the Corvette in 1965. The introduction, by Zora Arkus-Duntov, is interesting as Zora defends the use of drum brakes in the Corvette.

New Kid In Town: Big Block Debut

A new Corvette era was ushered in when a leading edge class of engine, fondly known as the "Big Block" was introduced late in the 1965 model year. At the time a huge horsepower race was taking place industry wide and the 396 cu. in. Turbo-Jet was the Corvette's ticket to the party. Rated at 425 hp, it furthered the Corvettes' Bad-Boy reputation. It also represented the first time a Corvette motor was rated at over 400 hp.

A new hood was required to clear the massive motor and a handsome new "bubble hood" design (above and left) was introduced. Below: Functional vents in the side nicely broke up the area. Indications are that due to supply problems at the time, a number of small block Corvettes left the factory with the big block hood.

Most of the horsepower advantage in the new engine could be found in the design of the heads which were nicknamed "porcupine heads", a reference to the way the valves were located at odd angles similar to the quills on a porcupine. The entire big block Corvette was thus sometimes known as the "fiberglass porcupine".

The physically much bigger engine required an enhanced cooling system. There was another drawback; approximately 150 lbs. of added weight, all of it on the front wheels. The weight distribution changed to 51% front / 49% rear, a handling disadvantage compared to the better balanced small block alternative.

396 side emblems signified new respect for impromptu Grand Prix stop light contestants.

A close examination of the specifications and the options list reveals an interesting fact that makes the 1965 Stingray particularly interesting to car collectors. 1965 was both the first year for all wheel disc brakes and the last year for the fuel injected engine. The two magic performance features would not appear together until 17 years later in the 1982 Corvette. In 1965, fuel injection cost an extra $538.00, adding over 13% to the price of a convertible. The 396 cu. in. motor added only $292.70 to the bottom line yet was rated at 425 hp; 50 more than the fuelie. With the fuel injection system's reputation for complexity and maintenance requirements well known, the days were numbered for the option that first shook the automotive high performance world in 1957.
