Brake System Rating Test Code - Commercial Vehicles

2023-01-09

CURRENT

J880_202301

This code is intended for commercial vehicles over 4500 kg (10 000 lb) with brake systems having typical service pressure ranges 0 to 14.1 mPa (0 to 2050 psi) hydraulic or 0 to 830 kPa (0 to 130 psi) air and is not directly applicable to vehicles with other systems. Air over hydraulic systems are to be tested as air systems.

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.
