First introduced as standard equipment on the 1965 Lincoln and Thunderbird, and as optional equipment on the 1965 Mustang, the disc brake was released as the power option on all 1968 Ford-built car lines.
Two sizes are available: one for the custom cars, which use a 15 in. diameter wheel; the other for the light cars using a 14 in. diameter wheel.
The problems encountered, the tooling changes necessary, and the equipment finally used for developing the floating caliper disc brake are described.
