Abstract

Disk brake comprising an electrical wear sensor with an electrical connector (17′), a caliper (10) having an opening (8) and at least one pin (13) fixed to the caliper between two opposite sides of the opening and means for fixing the connector (17′) to the caliper (10). To avoid special processing operations of the caliper body and to provide an easy and rapid assembly of the connector, the fixing means comprise a carrier element (20) made of shaped sheet metal that has a first part (21, 26) to which the connector (17′) is fixed and a second part (23-25) that engages with the pin (13) and the edges of the opening (8) to provide a firm attachment of the carrier element (20) to the caliper (10).

Claims

1. A disk brake comprising:

an electrical wear sensor with an electrical connector;

a caliper having an opening and at least one pin fixed to the caliper between two opposite sides of the opening; and

means for fixing the connector to the caliper, wherein said fixing means comprise a carrier element made of shaped sheet metal that has a first part to which the connector is fixed and a second part that engages with the pin and the edges of the opening to provide a firm attachment of the carrier element to the caliper.

2. A disk brake in accordance with claim 1, wherein the second part of the carrier element has a hole to provide a passage for the pin.

3. A disk brake in accordance with claim 2, wherein the second part of the carrier element is bent at a right angle and extends along two adjacent sides of the opening of the caliper.

4. A disk brake in accordance with claim 3, wherein the caliper is provided with a rib along at least one side of the opening and wherein the second part of the carrier element is shaped in such a way as to have a stirrup that embraces said rib.

5. A disk brake in accordance with claim 3, wherein the second part of the carrier element has an end bent in the manner of an L that rests on an edge of the opening.

6. A disk brake in accordance with any one of the preceding claims, wherein the first part of the carrier element and the connector has complementary snap-type engagement elements.

7. A disk brake in accordance with claim 6, wherein the complementary snap-type engagement means has a tab provided on the sheet-metal carrier element.
