Brake Rotor Thermal Cracking Procedure for Vehicles Below 4 540 kg GVWR
This recommended practice is derived from common test sequences used within the industry. This procedure applies to all on-road passenger cars and light trucks up to 4 540 kg of GVWR. This recommended practice does not address other aspects such as performance, NVH, and durability. Test results from this recommended practice should be combined with other measurements and dynamometer tests (or vehicle-level tests), and acceptance criteria to validate a given design or configuration.
This recommended practice provides a standard laboratory method and performance criteria to assess brake rotors for crack initiation and crack propagation during high-energy brake applications.
The SAE Task Force acknowledges the developments and best practices from different European working groups and regulatory entities as the backbone of this recommended practice.
