Abstract
A brake caliper () includes a first caliper arm () that opposes a first frictional surface () of a vehicle wheel () and a second caliper arm () that opposes a second frictional surface () of the same. A movable brake pad () is supported by the first caliper arm () and applies a braking force to the first frictional surface (). A plurality of pistons () which drive the movable brake pad () in accordance with expansion of a diaphragm () provided in the brake caliper (), and a guide member () that guides displacement of the plurality of pistons () in a right-angle direction relative to the first frictional surface () are provided, and therefore the movable brake pad () applies an even braking force to the vehicle wheel () in cooperation with a fixed brake pad () fixed to the second caliper arm ().
