Abstract
A brake apparatus includes a motor-based braking unit driven by control of an ECU and equipped with a BIR operating unit, that is, a BIR-equipped braking unit having a BIR (Ball In Ramp) function of generating straight movement force using changes in path of balls disposed between ramps rotating, such that it can achieve F-S (Fail-Safe) and generate emergency braking force for safety by operating the BIR operating unit using a pedal-coupled cable only by operating a brake pedal even if a motor of the motor-based braking unit fails.
