Description / Abstract:
This SAE Recommended Practice presents service brake performance
requirements for brakes systems of all combinations of new
passenger cars and new trailers (braked or unbraked) intended for
roadway use (excluding special-purpose vehicles such as ambulances,
hearses, etc.). Acceptable performance requirements are based on
data obtained from SAE J134.
Purpose-The purpose of this document is to
establish the minimum service brake system performance requirements
with regard to:
STOPPING ABILITY
Of cold brakes as affected by vehicle speed.
Of hot brakes as affected by vehicle speed and duty cycles.
Of cold brakes during emergency or inoperative power assist
conditions.
PEDAL FORCE-Maximum and/or minimum force allowable.
BRAKE STABILITY
BRAKE SYSTEM INTEGRITY
