- A method of making retention features on a brake pad retention plate, comprising providing a blank plate, wherein the blank plate comprises a brake pad facing surface ; forming, in the brake pad facing surface, a plurality of rows wherein each of the plurality of rows comprises a plurality of tooth features and a corresponding plurality of gutters where each gutter of the plurality of gutters comprises a first side and a second side , wherein the forming step comprises: upsetting a first set of the plurality of rows by forming each of the plurality of tooth features on the first side of the corresponding plurality of gutters, wherein the first set of the plurality of rows comprises at least two successive rows; and upsetting a second set of the plurality of rows by forming each of the plurality of tooth features on the second side of the corresponding plurality of gutters, wherein the second set of the plurality of rows comprises a single row successive to the first set; and characterised in that the forming step further comprises compressing each of the plurality of tooth features with a press wherein each of the tooth features bends at an inflection point to form a base portion extending vertically from the brake pad facing surface and a mezzanine portion extending horizontally over the gutter, such that a capture chamber is formed between the mezzanine portion and the gutter and the capture chamber has an opening configured to allow material to enter the capture chamber. providing a blank plate, wherein the blank plate comprises a brake pad facing surface ; forming, in the brake pad facing surface, a plurality of rows wherein each of the plurality of rows comprises a plurality of tooth features and a corresponding plurality of gutters where each gutter of the plurality of gutters comprises a first side and a second side , wherein the forming step comprises: upsetting a first set of the plurality of rows by forming each of the plurality of tooth features on the first side of the corresponding plurality of gutters, wherein the first set of the plurality of rows comprises at least two successive rows; and upsetting a second set of the plurality of rows by forming each of the plurality of tooth features on the second side of the corresponding plurality of gutters, wherein the second set of the plurality of rows comprises a single row successive to the first set; and characterised in that the forming step further comprises compressing each of the plurality of tooth features with a press wherein each of the tooth features bends at an inflection point to form a base portion extending vertically from the brake pad facing surface and a mezzanine portion extending horizontally over the gutter, such that a capture chamber is formed between the mezzanine portion and the gutter and the capture chamber has an opening configured to allow material to enter the capture chamber. upsetting a first set of the plurality of rows by forming each of the plurality of tooth features on the first side of the corresponding plurality of gutters, wherein the first set of the plurality of rows comprises at least two successive rows; and upsetting a second set of the plurality of rows by forming each of the plurality of tooth features on the second side of the corresponding plurality of gutters, wherein the second set of the plurality of rows comprises a single row successive to the first set; and characterised in that the forming step further comprises compressing each of the plurality of tooth features with a press wherein each of the tooth features bends at an inflection point to form a base portion extending vertically from the brake pad facing surface and a mezzanine portion extending horizontally over the gutter, such that a capture chamber is formed between the mezzanine portion and the gutter and the capture chamber has an opening configured to allow material to enter the capture chamber. <EOS>
