Abstract
A brake apparatus is provided that can make a ratio between a front wheel braking force and a rear wheel braking force that is actually generated into an arbitrary ratio. This brake apparatus includes a pedal operation detection section that detects a pedal stroke or a brake pedal force produced by a brake pedal operation; a brake caliper that is provided in each wheel of a vehicle and that generates a caliper force that is in accordance with a detection value of the pedal operation detection section; a load estimation section that estimates a load of each of the wheels; and a force generation section that, after judging that braking is performed in a state in which a load difference exists between left and right wheels of the vehicle based on a value that is estimated by the load estimation section, even if the pedal operation detection section detects a pedal stroke or a brake pedal force that is the same as for the braking at a time of judging or for braking prior to the judging, generates a caliper force that is different to the caliper force before the judgment.
