Abstract
A vehicle brake system is provided that includes (or is formed from) a back plate configured to support a composite pad, at least one conditioning insert coupled to the back plate and configured to contact a surface of a wheel during a braking event and thereby to condition at least a portion of the surface of the wheel, and fins coupled with the at least one conditioning insert and configured to conduct heat generated by contact of the at least one conditioning insert with the at least the portion of the surface of the wheel away from the at least one conditioning insert.
Claims22
A system, comprising:
- a back plate extending along opposite circumferential directions and configured to support a composite pad that moves radially with respect to a disc and contacts a circumferential surface of the disc to slow or stop rotation of the disc;
- and
- elongated tines coupled with the back plate, including elongated tines disposed at a first circumferential end of the back plate and elongated tines disposed at a second circumferential end of the back plate,
- wherein the elongated tines disposed at the first circumferential end and the elongated tines disposed at the second circumferential end:
- extend away from each other and are elongated in the opposite circumferential directions, and
- are configured to conduct heat generated by contact of the composite pad with the circumferential surface of the disc away from the composite pad.

- and
- at least one conditioning insert coupled to the back plate and configured to contact a surface of the disc during the braking event and condition at least a portion of the surface of the disc;
- and
- elongated tines coupled with one or more of the back plate or the at least one conditioning insert, including elongated tines disposed at a first circumferential end of the back plate and elongated tines disposed at a second circumferential end of the back plate,
- wherein the elongated tines disposed at the first circumferential end and the elongated tines disposed at the second circumferential end:
- extend away from each other in the opposite circumferential directions;
- and
- are configured to conduct heat generated by contact of the composite pad with the circumferential surface of the disc away from the composite pad.

- wherein the elongated tines disposed at the first circumferential end and the elongated tines disposed at the second circumferential end:
- extend away from each other and are formed as cantilevered beams that are elongated in the opposite circumferential directions, and
- are configured to conduct heat generated by contact of the composite pad with the circumferential surface of the disc away from the composite pad.
