摘要： A brake disc (10) for arrangement in a vehicle to rotate around a rotational axis (11). First and second annular braking surfaces (15a-b) extend radially between an inner braking surface radius (R i ) and an outer braking surface radius (R o ). Each of the first and second braking surfaces has an annular proximal portion (17), an annular distal portion (18), and an annular central portion (19). At least one of the first and second braking surfaces is structured to protrude from a base plane (16a, 16b) perpendicular to the rotational axis (11) to exhibit a surface profile cross-section (14a, 14b) with a plane (24) including the rotational axis (11). A protrusion distance (h a (r), h b (r)) from the base plane (24) to the surface profile cross-section (14a, 14b) varies with radial distance (r) from the rotational axis (11) in such a way that a central portion distance (d central ) is longer than each of a proximal portion distance (d proximal ) and a distal portion distance (d d istal).
