Abstract: A floating disc brake has a supporting bracket, a caliper body connected to the supporting bracket, a first friction pad on a first side of the caliper body, a second friction pad on a second side of the caliper body, fixed to the caliper body, a first piston connected to the first friction pad and a second piston that can freely rest on the first friction pad forming a positioning surface which can abut against a resting surface of the supporting bracket. The first and second pistons can be actuated independently so that a rearward movement of the first piston towards the first side detaches the first friction pad from the brake disc, and a rearward movement of the second piston towards the first side, with the positioning surface abutting against the resting surface moves the caliper body together with the second friction pad towards the second side and detaches the second friction pad from the brake disc.
