A 2-3/4 inch diameter propeller shaft connects the transmission with the rear axle. It is equipped with a ball-and-trunnion front universal joint and a cross-type rear joint. The rear axle has a 3.23 ratio. It is a standard 8-3/4 inch axle with spring seats modified for attachment of the shock absorbers.
The Turbine Car has power brakes, with a self-adjusting servo-type brake assembly, 10-inch diameter x 2.5 inches wide, at each wheel. The hydraulic master cylinder is operated by an air booster instead of being vacuum-suspended, since no vacuum is available from the turbine engine. Air pressure is provided by a continuous-duty, electric-motor-driven compressor and a reservoir tank. Pedal travel is only 2.83 inches, which is about 2 inches less than for 1963 power brakes, without compromising brake "feel."
Parking brakes are provided by manual operation of the rear wheel service brakes through a cable remote control. They are applied by upward movement of a lever mounted on the console and are released by a push button on the lever. An equalizer assembly is located immediately behind the brake lever mechanism inside the console tube and above the propeller shaft. The cable adjustment nut is accessible through the rear console ash receiver opening. Cables are routed rearward through the console and then to the rear wheels. This direct routing improves efficiency and makes it easier to apply the parking brakes.
The car has 14- inch wheels. The tires, specially engineered for the Turbine Car, are 7.50 x 14, 4-ply rayon-cord with a decorative "turbine wheel" design on white sidewalls.
