A brake lining is provided that is to be pressed against a sliding surface of a brake disk fastened to a wheel or an axle of a railway vehicle. The brake lining includes: a plurality of friction members arranged to be spaced from each other, each of the friction members having a front surface that is to face the sliding surface; a back board fastened to a back surface of each of the friction members; and a base plate supporting each friction member at a region including a center portion of the respective friction members. Two friction members are taken as a pair, and the back board that is fastened to the pair of friction members is a one-piece member, and a width of the back board at a space between the friction members of the pair of friction members is greater than a width of the friction member.

The aim of the invention is to provide a running gear with a mount for a brake linkage on a bogie, wherein the mount has a long service life and requires little maintenance. The transmission of shocks and vibrations between the brake linkage and the bogie is reduced, and the bogie and the brake linkage are electrically insulated from each other. A running gear for a rail vehicle including a bogie and a brake linkage is proposed, having at least one bearing element. The brake linkage is mounted on the bogie and/or is connected to the bogie by means of the at least one bearing element, and the at least one bearing element has a plastic and/or consists of a plastic.

A vehicle disc brake apparatus is adapted for use with a vehicle including a brake disc and includes a bracket configured to be fixed to the vehicle, a caliper body coupled to the bracket and pivotal about a pivotal axis that extends in a front-rear direction of the vehicle, a brake cylinder device that generates braking force, and two levers arranged on the caliper body. The levers transmit the braking force to the brake disc of the vehicle. The bracket and the caliper body are coupled at a position located toward the brake disc from the brake cylinder device.
