Brake Rating Power Requirements - Truck and Bus

2019-07-18
CURRENT
J257_201907
The minimum performance values in this SAE Recommended Practice are applicable to vehicles with brake systems having typical service pressure ranges 0 to 16.6 MPa (0 to 2400 psi) hydraulic or 0 to 945 kPa (0 to 135 psi) air only. SAE J880 not only provides for determining maximum brake rating power capability, but also permits verification of any desired or arbitrary level such as the requirement established herein. The determining criteria for deciding brake rating power capability are: a. Cold brake stopping ability. b. Fade as a result of brake power absorption. c. Hot brake stopping ability following brake power absorption. d. Brake system stability following brake power absorption. e. Functional and structural integrity of brake system following test.

WIP
J1854
This SAE Recommended Practice establishes performance guidelines for the threshold pressure and brake force output of the brakes on the axles of air braked towing trucks, truck-tractors, truck-trailers, and converter dollies with GVWRs over 10 000 lb designed to be used on the highway in combination with other air braked vehicles of this type in commercial operations. The purpose of this document is to establish target threshold pressures and brake force outputs with reference to brake application pressures as measured at the rear control line gladhand of truck-tractors and towing trucks, the front control line gladhand of non-towing trailers, and the front and rear control line gladhand of towing trailers and dollies.
