This SAE Recommended Practice establishes dimensions and tolerances for the interface between inboard mounted disc brake rotors and disc wheel hubs. This document is intended for inboard mounted disc brake rotors and disc wheel hubs for Class 5, 6, 7, and 8 commercial vehicles. Special and less-common applications are not covered.
Rationale:
This SAE Recommended Practice has been revised to incorporate new designs that have emerged in the industry, with splined interfaces between hub and rotor. These designs are now included in the hat and flat rotor descriptions. Section 3.2 was added to comment on the splined design features and clarify their current proprietary nature.
