1. Scope--This SAE Recommended Practice establishes a uniform procedure for the level road test of the brake systems of all combinations of new multipurpose passenger vehicles, new light-duty trucks up to and including 4500 kg (10000 lb), and new passenger cars when coupled with new trailers (braked or unbraked).

1.1 Purpose--The purpose of the test code is to establish a uniform test procedure to determine capabilities with regard to:

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

1.1.2 Brake system integrity within the limits of this test.

1.1.3 Stopping ability during:

1.1.3.1 Emergency (partial brake) conditions.

1.1.3.2 Inoperative power assist conditions.
