A block brake assembly for a railway vehicle includes a holder for one or more brake blocks which, when the brake is engaged, are pressed against the periphery of the vehicle wheel. The holder comprises a pair of spaced side members, and the brake block or blocks have guide lugs and attaching lugs thereon projecting between the members. The blocks are retained against the holder by a leaf spring which is pivotally mounted at one end to the holder, projects through openings in the attaching lugs and bears against a lock pin on the holder at an opposite end thereof. A pair of stop elements on the holder bear against outer sides of a pair of the lugs for preventing tangential displacement of the block brake or brakes relative to the side members.
