<p>PROBLEM TO BE SOLVED: To provide a disc brake which can prevent a rapid rise of brake fluid temperature. SOLUTION: In this disc brake 1, a section of an inner/outer side piston 4a, 4b is formed in almost U-shape, a disc-shaped radiating plate 12a, 12b is provided in a location adjacent to a pad plate 6a, 6b in a side of each base part A of the piston 4a, 4b, even when friction heat generated in a pad 7a, 7b is transmitted to the piston 4a, 4b by this radiating plate 12a, 12b, this friction heat is partly radiated by the radiating plate 12a, 12b, by reducing heat transmitted to a brake fluid through the piston 4a, 4b, a rapid rise of brake fluid temperature can be prevented.</p> |
