Abstract: The present invention provides a friction management brake shoe adapted to engage the tread and the flange of a wheel of a railway vehicle via which the railway vehicle is guidably supported on a railed track. The friction management brake shoe comprises a brake lining affixed which has a braking surface engageable with the wheel tread of a wheel of a railway vehicle. The brake lining includes a first friction composition material formed with at least one of a solid high positive friction modifier and a solid very high positive friction modifier which establish a required friction level between the wheel tread and the railed track.
