The American Motors disc brake is a development which represents a significant step forward in automotive brakes. This development was a joint program between American Motors and the Bendix Automotive Products Division, combining the engineering skills and experience of both corporations.
This brake system, incorporating dual piston disc brakes on the front and non-servo drum brakes on the rear, was designed and developed against an advanced set of performance objectives. The new objectives recognize the increase in highway speeds on modern turnpikes calling for an increase in brake system high speed capabilities.
The design of the American Motors disc brake involves operating pressures and temperatures requiring a lining of special characteristics. The development of a proper lining was a vital part of the overall engineering program.
The use of Non-Servo drum brakes in the rear was the result of a complete review of the principles and objectives in front-to-rear brake balance. The conventional servo drum brake did not lend itself to the combination disc-drum brake system.
Lining life and brake noise presented challenging and unique problems ultimately solved in the final design brake system.
