SAE J291-1980 DETERMINATION OF BRAKE FLUID TEMPERATURE
Foreword-This Reafirmed Document has been changed only to reflect the new SAE Technical Standards Board Format.
1. Scope-This code provides a test procedure for obtaining and determining extremely high brake fluid temperature encountered in the brake system of a vehicle that is equipped with disc brakes. Vehicles in normal operation may or may not produce brake fluid temperatures that are obtained in this procedure.
1.1 Purpose-To establish a uniform procedure for obtaining and determining a maximum temperature of brake fluid in the automotive braking system of vehicles equipped with disc brakes. This procedure is a uniform means of heating the brakes and the brake fluid and is not a simulation of any other test procedure.
2. References-There are no referenced publications specified herein.
