In 1961 Caterpillar added self-adjusting brakes, beginning with 99E03106.

Production of 99E ended in 1965.

Production of 21F ended in 1968; it was replaced by a new Australian unit, with a 17K prefix. The new unit comes standard with a D333 engine, electric start, and self-adjusting brakes. Production of 17K ended in 1975.

The Caterpillar 12E was replaced by the Caterpillar 12F.
