Patent number: 9765833Abstract: A disc brake assembly includes a rotor with an ABS tone ring insert assembly that functions as a rotation indicator in an anti-lock braking system. The insert is positioned in the hat of a rotor disc in a spaced relationship and is mounted to the mounting flange of the rotor disc. Forming the ring insert separately from the rotor disc also allows different coating materials to be used on the tone ring that may be more heat resistant. The ring insert assembly can be made of powder metal or made as a cast iron cylinder with a toothed cap made of powder metal having a corrosion resistant coating. Cost savings can be realized along with high performance when only a portion of the assembly if made of powder metal and coated.Type: GrantFiled: July 19, 2011Date of Patent: September 19, 2017Assignee: PERFORMANCE FRICTION CORPORATIONInventors: Donald L. Burgoon, Joseph Bradley Dalton, Scott Andrew Paul, Craig A. Van Harken
