Two sliding bushes (5, 6) for an axial displacement of the brake caliper (1) are disposed on a brake support, and two flange faces (8, 8a) are disposed axially parallel to each other on the tensioning side (2) between the sliding bushes (5, 6) for receiving a sensor resetting unit (9). ## Claims ### Claim 1 A brake caliper (1) for a disc brake, having a tensioning side (2) and a rim side (3), comprising: a brake cylinder flange face (4), which, for receiving a brake cylinder, is disposed on the tensioning side (2); a first sliding bush (5) and a second sliding bush (6) for an axial displacement of the brake caliper (1) disposed on a brake support; a first flange face (8) and a second flange face (8a), which, for receiving a sensor resetting unit (9), are disposed axially parallel to each other on the tensioning side (2) between the first sliding bush (5) and the second sliding bush (6), wherein the brake caliper (1) has at least one of a first rib and a second rib, the first rib (10) being disposed on the tensioning side (2) between the first sliding bush (5) and the first flange face (8), in a direction radially opposed to the brake cylinder flange face (4), and the second rib being disposed between the second sliding bush (5) and the first flange face, in a further direction radially opposed to the brake cylinder flange face (4). ### Claim 2 (depends on 1) The brake caliper (1) as claimed in claim 1, wherein an external contour of the at least one of the first rib (10) and the second rib (10a) corresponds to or is larger than an external contour of the sensor resetting unit (9) to be received by the first and second flange faces (8, 8a). ### Claim 3 (depends on 1) The brake caliper (1) as claimed in claim 1, wherein the at least one of the first rib (10) and the second rib is disposed at a spacing distance (18) from the first and second flange faces (8, 8a). ### Claim 4 (depends on 1) The brake caliper (1) as claimed in claim 1, wherein the at least one of the first rib (10) and the second rib (10a) is shaped from a brake caliper housing (11). ### Claim 5 (depends on 1) The brake caliper (1) as claimed in claim 1, wherein the at least one of the first rib (10) and the second rib (10a) is disposed on a brake caliper housing (11) in a direction radially opposed to the brake cylinder flange face (4). ### Claim 6 (depends on 1) The brake caliper (1) as claimed in claim 1, wherein the at least one of the first rib (10) and the second rib (10a) is formed from the same material as the brake caliper (1). ### Claim 7 (depends on 1) The brake caliper (1) as claimed in claim 1, wherein the at least one of the first rib (10) and the second rib has a width (B) of at least 4 mm. ### Claim 8 (depends on 1) The brake caliper (1) as claimed in claim 1, wherein the first rib (10) and the second rib (10a) extend generally parallel to the first flange face (8) and the second flange face (8a). ### Claim 9 (depends on 1) The brake caliper (1) as claimed in claim 1, wherein the brake cylinder flange face is above the first and second ribs (10, 10a) and the first and second ribs (10, 10a) are below the brake cylinder flange face (4). ### Claim 10 (depends on 1) The brake caliper (1) as claimed in claim 1, wherein the first rib (10) and the second rib (10) extend generally perpendicular to the axial direction. ### Claim 11 (depends on 1) The brake caliper (1) as claimed in claim 1, wherein the first rib (10) and the second rib (10) are spaced away from the first sliding bush and the second sliding bush. ### Claim 12 (depends on 1) The brake caliper (1) as claimed in claim 1, wherein the first rib (10) and the second rib (10a) are axially recessed relative to the first and second flange faces (8, 8a) and the first and second flange faces (8, 8a) project axially in relation to the first and second ribs (10, 10a) such that a support plate (17) of a sensor resetting installation is axially spaced from the first and second ribs (10, 10a). ### Claim 13 A brake caliper (1) for a disc brake, having a tensioning side (2) and a rim side (3), comprising: a brake cylinder mounting face (4) disposed on the tensioning side (2);
