FIELD: transport.
SUBSTANCE: invention relates to machine building, particularly, to disc brakes. Claimed brake shoe comprises bearing plate of plastic, friction lining moulded at said bearing plate and metallic reinforcing plate built in said bearing plate. Said bearing plate includes a solid peripheral structure an inner structure including the multiple cavities partially filled with the friction lining material. Some of said cavities are composed of through chambers. Note here that the latter occupy the area making 4.5% of the friction lining surface area in contact with the bearing plate. Said reinforcing plate comprises through bores aligned with appropriate bearing plate cavities and shaped thereto. Friction lining material is partially filled in via said through bores.
EFFECT: better adhesion between the lining and the bearing plate.
