摘要:
A radially mounted disk brake has a caliper body secured to a support member secured to a vehicle body. The caliper body has mounting holes extending in a direction perpendicular to the axis of rotation of a disk rotor. Large-diameter hole portions are formed at the openings of the mounting holes on the side thereof closer to the support member. The large-diameter hole portions are fitted with the side wall surfaces of cylindrical step portions provided on the support member in such a manner that gaps are formed between the bottoms of the large-diameter hole portions and the distal end surfaces of the step portions. The center of the axial length of each mounting hole is positioned radially outward of the disk rotor in the axial direction of the mounting hole with respect to a shortest-distance portion of the caliper body at which the distance between the center of a cylinder bore and the mounting hole is shortest.

A saddle-riding type vehicle includes a vehicle body, a pivot frame that supports a swing arm for rear wheel suspension, and a rear master cylinder disposed rearwardly of the pivot frame. A reservoir tank supplies hydraulic fluid to the rear master cylinder, and the reservoir tank is disposed between the pivot frame and the rear master cylinder. A portion of the swing arm, adjacent to the reservoir tank, is configured with a concave recess formed therein extending inwardly towards a longitudinal center line of the vehicle body. The reservoir tank is situated closer to a vehicle body inner side, and is deeper in the recess than the rear master cylinder.

A front disk brake includes a brake caliper having a pair of caliper side mount portions, and a caliper bracket having a pair of bracket side mount portions. The brake caliper includes an oblong-shared lower-side counterbore and a circular-shaped upper-side counterbore, the lower-side counterbore being oblong sectional shaped in the arrangement direction of the lower-side counterbore and the upper-side counterbore paired therewith. The caliper bracket includes lower-side and upper side circular-shaped counterbores which are opposed, respectively, to the counterbores of the brake caliper. The brake caliper is fixed to the caliper bracket by mounting fastening bolts in bolt passing holes and screw holes formed respectively in the mount portions. The bolt passing holes and the screw holes are provided at their portions on the sides of opposed surfaces with counterbores in which collar members are to be fitted.

To provide a disk brake which makes it possible to efficiently manufacture a brake caliper and a vehicle body side support portion, while maintaining the positioning accuracy of the brake caliper. A front disk brake includes a brake caliper provided with a pair of caliper side mount portions and a caliper bracket provided with a pair of bracket side mount portions. The brake caliper is fixed to the caliper bracket by mounting fastening bolts in bolt passing holes and screw holes formed respectively in the mount portions. The bolt passing holes and the screw holes are provided at their portions on the sides of opposed surfaces with counterbores in which collar members are to be fitted. The lower-side counterbore in the brake caliper is formed in an oblong sectional shape elongate in the arrangement direction of the lower-side counterbore and the upper-side counterbore paired therewith.
