SAE J2686 (DEC2022)

This SAE Recommended Practice is intended for qualification testing for brake drums used on highway commercial vehicles with air brakes using an inertia-dynamometer procedure.

This document consists of two distinct tests:

  • Part A: durability and speed maintenance test,
  • Part B: heat check drag sequence test.

Each test can be considered to be an independent evaluation of the brake drum which tests different properties.
