Abstract
A brake apparatus has a good brake operation feel provided by a combination of a link mechanism and a brake booster. The link mechanism changes a lever ratio so that the lever ratio is gradually decreased as a pedal stroke is increased after the pedal stroke reaches a predetermined point. The brake booster increases a rate of increase of an output force so that the rate of increase is increased as an input force is increased. A brake characteristic of the brake apparatus as a whole exhibits a linear relationship relative to the deceleration of the vehicle, the brake characteristic being defined as an inclination of the deceleration against the pressing force input to the link mechanism. One of the link mechanism and the brake booster may be used alone in a brake apparatus to provide their respective effect to a brake apparatus.
