Brake Drum Qualification Recommended Practice
Description
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 Recommended Practice consists of two distinct tests: Part A – durability and speed maintenance test, and 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.
