Drift handbrake, also known as a hydraulic handbrake or e-brake, is a device used in motorsports such as drifting and rally driving to initiate and maintain a controlled drift while cornering. It is a secondary braking system that allows the driver to lock up the rear wheels independently of the main braking system, creating a controlled oversteer that helps the car slide through turns. The drift handbrake is typically operated by a lever or button located within easy reach of the driver’s hand and is connected to the rear brake calipers or a separate hydraulic system
