La présente invention concerne une structure support de corps d'étrier pour frein à disque de véhicule configurée de façon, d'une part que les chapes de freins recevant les piges d'étriers puissent être facilement réalisées sur le dispositif de suspension du véhicule, et d'autre part que le montage des piges d'étriers sur leurs chapes de freins soit simple et facile pour permettre un travail plus efficace. Les piges (6, 7) comprennent, d'une part des corps de piges (6a, 7a) qui coulissent dans des trous de guidage (8m, 8n) ménagés dans les corps d'étriers (8), et d'autre part des boulons de fixation des piges (6b, 7b) permettant de fixer les corps des piges de (6a, 7a) sur les chapes de freins correspondantes (3, 5). Ces chapes de freins (3, 5) présentent des surfaces de montage (3f, 5e) qui viennent sur le côté opposé d'un rotor de disque et qui se présentent dans un plan (F3) qui passe par l'axe central de la fourche avant (4) et qui est déporté, par rapport au cadre du véhicule, plus vers l'extérieur qu'un plan (F1) parallèle à une surface latérale du rotor de disque (2), tout en restant parallèle audit plan (F1).
