A disk brake having a brake caliper, which engages axially in a U shape around a rotatable brake disk is provided. The disk brake includes a caliper bridge, two caliper limbs and at least one actuating device. At least one brake lining is mounted in an axially movable fashion in the brake caliper. The caliper bridge has, in the peripheral direction, at least three substantially axially extending supports, wherein two of the supports are embodied as a main support and one support is embodied as a central support. These supports connect the two caliper limbs and in the process form two windows and axially project beyond the brake disk. The central support projects both beyond the brake disk and beyond the brake lining in the axial direction.
