The invention proposes a disc brake having a caliper (14) slidably mounted on a fixed support (10) by at least one axial column (16) slidingly received in an open bore (58) in the caliper (14). The brake is characterized in that the column (16) includes an axial abutment associated with the sleeve (40) in order to limit the axial displacements of the latter with respect to the caliper (14) when the stem (46) of the bolt (42) is unscrewed from the fixed support (10). The abutment (86) consists of a crown (70) of U-shaped cross-section the inner cylindrical sidewall (72) of which is mounted in the bore (43) inside the sleeve (40) and the flat annular end (76) of which is held tight between the end (52) of the sleeve and the fixed support (10) when the column (16) is fixed to the latter, the abutment surface (86) consisting of the extreme free edge of the outer cylindrical sidewall (74) of the crown (70).
