Abstract
In a disc brake apparatus, by means of an actuator which operates in accordance with an operation force, a braking piston fitted into a cylinder portion of a caliper is axially driven so as to push a pad toward a disc rotor. A friction force in a circumferential direction of the disc rotor between the pad and the disc rotor is taken out as an anchor load, and is converted to a servo load by means of a servomechanism. The servo load is applied to the braking piston. The servomechanism is equipped with a hydraulic mechanism (a pressure-reducing control valve, a pressure-increasing control valve, and a reservoir tank) capable of increasing or decreasing the servo load. An electric controller controls the hydraulic mechanism in accordance with the operation force and the anchor load.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
