Abstract
A disc brake includes a piston seal made of rubber that is shaped to fit into a seal groove on the inner surface of a cylinder of a caliper for a brake piston. To prevent braking effectiveness from being impaired, even if the temperature of a caliper rises in a disc brake for a vehicle, the piston seal and/or the seal groove is shaped to control and contain the effects of thermal expansion due to the heat of the disc brake. The clearance between the piston seal and the seal groove is removed and clearance is provided between parts of the periphery of the piston seal and the seal groove.
