Les segments (7, 9) sont disposés de façon opposée de part et d'autre d'une roue (2) ou d'un disque de fixation et sont fixés ensemble et à la roue (2) ou au disque de fixation à l'aide d'au moins un moyen de fixation (6) dans une zone de fixation (15, 16). Afin que le disque de frein présente de meilleures caractéristiques en termes de dilatation thermique, il est proposé de prévoir pour le centrage et la fixation de chaque segment (7, 9) au moins un palier fixe (17) et au moins un palier libre (18) qui est prévu au niveau de la zone de fixation (15, 16). Le palier libre (18) est configuré et implanté de manière à permettre une dilatation non radiale du segment (7, 9).
