  • Patent number: 9365259
    Abstract: A disc brake caliper comprises a caliper main body and an insert member. The caliper main body comprises a first portion, a second portion, a connecting portion, a first hole and a second hole. The connecting portion, the first portion and the second portion are formed as a single unitary member. A banjo fixing member is to be attached to the first hole. The second hole is provided apart from the first hole and extending from the first portion to the connecting portion so as to at least partially overlap the slit in the connecting portion. The insert member is configured to be inserted into the second hole. The insert member extends from the first portion to the connecting portion so as to at least partially overlap the slit in the second hole.
