In a vehicle disc brake system, the brake pads straddle the friction pads placed opposite to each other on both sides of the disc.
A sliding caliper that supports a caliper, which has an inner part with a pressing means for pressing the back surface of one friction pad and an outer part that contacts the back surface of the other friction pad, on a bracket fixed to the vehicle body so as to be movable in the disk axial direction. Since the pin is screwed onto the bracket, its tip is located near the disk, which is a heat source, and is susceptible to the effects of frictional heat generated during braking.
Therefore, for example, when a bracket made of aluminum alloy and a sliding pin made of steel are used, there is a risk that a difference in thermal expansion will occur and problems will occur in the screwed portion.
