Disc brake incorporating an assembly of a crown (11) and a brake bowl (12), with the brake bowl (12) incorporating a circular base (12a), extended radially and externally by lugs (12b), with the crown accommodating a number of fingers (13) protruding externally into the interior volume of the crown (11). The lugs (12b) have a staged configuration with, at the end, a hood form (12d) internally establishing a housing for each of the fingers (13); the lugs have an access opening in unclosed ‘U’ form; the lugs (12b) are oriented in the same direction, with their opening part on the same side. After assembly of the brake bowl and the crown, the lugs are closed around the fingers, by distortion and flowage of the material around the finger, leaving them a capability for axial movement.
