A mechanically operated sliding saddle disc brake has a fixedly positioned brake carrier 1, a brake saddle 2 mounted in the brake carrier and slidably displaceable parallel to the rotational axis of the wheel to be braked, with two shanks 2', 2' which straddle a brake disc which is rotationally fast with the wheel, a piston 14 mounted in the first brake saddle shank 2' slidably displaceable parallel to the rotational axis of the wheel and connected to a pressure plate 12, a first brake lining carrier 4 positioned on pressure plate 12 which carries a brake lining 4' which can be brought into engagement on one side of the brake disc, a mechanically operated expansion mechanism supported on piston 14 and on the first brake saddle shank 2', a second brake lining carrier 3 positioned on second brake saddle shank 2' which carries brake lining 3' which can be brought into engagement with the other side of the brake disc, and guides 11, 11' positioned on brake carrier 1 for guiding and supporting the two brake lining carriers 3, 4. To ensure parallel positioning of the brake lining carriers to the brake disc and thus full surface engagement of the two brake linings on the brake disc both when the brake is inoperative and when it is operative, pressure plate 12 is connected to piston 14 via a projection 13 which allows rocking movements of pressure plate 12, pressure plate 12 is clamped to piston 14 via a compression spring screw bolt combination 15, second brake lining carrier 3 is supported on second brake saddle shank 2' by at least one cylindrical projection 6 having a crest line running tangentially to the brake disc and through the center of braking area of second brake lining 3', second brake lining carrier 3 is supported on abutment 7 near the free end of second brake saddle shank 2', and second brake lining carrier 3 is clamped to the second brake saddle shank 2' by helical springs 8.
