Abstract: The present invention relates to a disc brake for an automobile including a disc comprising an outer part made of carbon/carbon mounted to slide axially on an inner part fixed to a stub axle. Pads, configured as rings coaxial to the disc, define braking surfaces which totally cover the axial faces of the outer part. The pads, also preferably formed of carbon/carbon, are mounted in a pad support in the form of a cage thermally protected from the pads by radiators. Jacks are interposed between an annular shield of the pad support and one of the pads to shift the pad relative to the disc.
