Abstract
A disk brake having members for keeping the friction pads in contact with the disk rotor in such a way that the wear of the friction members and the energy loss are kept to a minimum. The disk brake has a disk rotor, friction pads provided opposed to each other on both sides of the disk rotor, a caliper formed with a fluid pressure cylinder at least on one side of the disk rotor, and a piston slidably received in the cylinder for selectively applying braking force to the disk rotor by pushing the friction pads into sliding contact with the disk rotor. A resilient member is disposed between the piston and one of the friction pads provided opposite the piston for biasing the friction pads toward the disk rotor by a predetermined stroke, thereby keeping the friction pads in contact with the disk rotor at a predetermined surface pressure even while the brake is not applied.
