A disc brake, comprising: a brake disk; a brake caliper arranged to straddle the brake disk; a brake caliper mount arranged to receive the brake caliper; and a brake pad, wherein the brake caliper mount includes brake pad abutment portions arranged to limit motion of the brake pad in a circumferential direction of the brake disk, the brake pad abutment portions including at least one generally radially-oriented brake pad insertion feature in the form of a generally radially-oriented groove extending generally parallel to an adjacent lateral side of the brake pad, and a radially-inner end of the groove meeting at least one lateral brake pad receiving feature oriented parallel to a rotation axis of the brake disk at an end of the lateral brake pad receiving feature axially away from the brake disk, the brake pad abutment portions are designed as mount horns, the brake caliper includes a brake pad opening sufficiently wide in the circumferential direction of the brake disk to permit the brake pad to pass through the caliper into the at least one radially-oriented brake pad insertion feature without removal of the caliper from the caliper mount, the brake pad includes at least one pad retention feature corresponding to the at least one lateral brake pad receiving feature of the caliper mount, and the at least one radially-oriented brake pad insertion feature and the at least one lateral brake pad receiving feature are arranged to permit the brake pad to move within the at least one radially-oriented brake pad insertion feature simultaneously radially and parallel to a friction face of the brake disc when the brake pad is aligned with the at least one radially-oriented brake pad insertion feature and to move axially toward or away from the brake disk while being retained within the disc brake by the at least one lateral brake pad receiving feature when the brake caliper is in an operative position. a brake disk;
