need to change my brake caliper to fit new calipers, can be of different model if these are hard to find, i cant seem to find the exact brake pads for these and lost the sample brake pads, the guy who replaced my brakes replaced with a smaller size and threw away the original ones, only saw it months after when it started eating the rotor that something is wrong, so im gonna change the whole caliper to get one which ill be able to find fitting pads for
