Abstract
An electro-mechanical brake including: a plurality of brake pads respectively mounted on front and rear wheels of a vehicle; and a processor configured to correct a first braking distribution ratio to determine a second braking distribution ratio, the braking distribution ratio being a ratio of a magnitude of a rear-wheel braking force distributed to the rear wheels to a magnitude of a front-wheel braking force distributed to the front wheels, wherein the processor calculates a wear amount of each of the plurality of brake pads, and determines the second braking distribution ratio based on the wear amount of each of the plurality of brake pads.

An electro-mechanical brake comprising:
- a plurality of brake pads respectively mounted on plurality of wheels of a vehicle including front and rear wheels;
- and
- a processor configured to correct a first braking distribution ratio to determine a second braking distribution ratio, each of the first and second braking distribution ratios being a ratio of a magnitude of a rear-wheel braking force distributed to the rear wheel to a magnitude of a front-wheel braking force distributed to the front wheel,
