Abstract
A vehicle brake system includes a back plate that may support a composite pad, and at least one conditioning insert coupled to the back plate and that may contact a surface of a wheel during a braking event and thereby to condition at least a portion of the surface of the wheel. Optionally, the back plate can define a U-shaped coupler that is centrally located and has two ends that are distal from the coupler. The back plate can have a centerline extending from a first end of the ends to a second end of the ends while passing through a center of the back plate, and the at least one conditioning insert can be disposed off of the centerline so as to not be centrally disposed.
Claims17
A vehicle brake system, comprising:
- a back plate configured to support a composite pad;
- and
- at least two conditioning inserts 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;
- wherein the back plate defines a U-shaped coupler that is centrally located and has two ends that are distal from the coupler, the back plate having a centerline extending from a first end of the two ends to a second end of the two ends while passing through a center of the back plate, and the at least two conditioning inserts are disposed off of the centerline so as to not be centrally disposed.
A vehicle brake system, comprising:
- a back plate configured to support a composite pad, the back plate elongated from a first end to a second end;
- and
- conditioning inserts coupled to the back plate proximate to the first and second ends of the back plate, the conditioning inserts 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;
- wherein the back plate has a centerline extending from the first end to the second end while passing through a center of the back plate, and at least one of a first conditioning insert or a second conditioning insert is disposed off of the centerline so as to not be centrally disposed.
A method comprising:
- obtaining a back plate configured to support a composite pad;
- and
- forming at least one conditioning insert coupled to the back plate and positioned 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
- wherein the back plate is formed to have a U-shaped coupler that is centrally located and two ends that are distal from the coupler, and the at least one conditioning insert is formed proximate to one of the two ends of the back plate;
- and
- wherein the back plate is formed to have a centerline extending from a first end of the two ends to a second end of the two ends while passing through a center of the back plate, and the at least one conditioning insert is formed in a location off of the centerline so as to not be centrally disposed.
