A brake caliper for a disk-type brake is disclosed having a prefabricated, cast-in-place cylinder bore liner. The liner is made of a machinable material, preferably steel, and the caliper body is made of a lightweight material, preferably aluminum. The caliper body is cast around the cylinder liner so that no further machining of the caliper bore is required. A reinforcing arm may be provided extending from the cylinder liner through the bridge portion of the caliper. A method for making the caliper is also disclosed in which the cylinder liner is positioned within a die cavity and molten metal material is cast around the liner to incorporate the liner into the caliper body.
