Abstract:
A railroad brake shoe has a pad has a central axis with an arcuate front face which terminates at upper and lower edges. Normal forces at an edge define a line of action. The pad includes support material on the side of the line of action opposite the central axis. The support material resists edge chipping and the formation of edge cracks.
Example brake pads and methods of manufacturing brake pads are disclosed. An example brake pad for use with a rotor of a disc brake assembly includes a curved substrate. The brake pad also includes a plurality of grooves in the curved substrate, the plurality of grooves defining a plurality of contact surfaces, wherein the plurality of grooves extend radially with respect to a rotational axis of the rotor.
