This SAE Recommended Practice establishes a uniform laboratory dynamometer method of testing all classes of passenger car brake systems.

Purpose—The purpose of the document is to establish brake system capabilities with regard to:

Deceleration versus input, as affected by speed, brake temperature, and usage.

Brake system integrity.

Stopping ability during emergency or inoperative power-assist conditions.

Rationale—In reviewing the document it was found to be obsolete and has been replaced by SAE J2784.
