Abstract
A friction device for a vehicle having a flanged wheel (with a wheel flange and wheel tread) includes a backing plate and a friction structure. The backing plate may interface with a brake actuator of the vehicle. The friction structure is attached to the backing plate and comprises a friction material; the friction structure has a longitudinal flange side, a longitudinal rim side, and two opposing ends, and defines a brake surface for engaging the flanged wheel for braking. The friction structure includes an extended volume portion of the friction material on the longitudinal flange side, which defines a flange contact region of the brake surface. The flange contact region may at least partially engage the flange and to align the friction device with the wheel tread, e.g., the flange contact region may be complementary in shape to at least part of the flange.
