Drifting and Rally driving requires extensive use of the handbrake, which can show weaknesses in standard cable type handbrakes. The hydraulic system eliminates the weaknesses as in the standard cable type handbrakes. The hydraulic system connects into the brake line that runs to the rear calipers and requires a lot less force to completely lock both rear wheels when needed. A hydraulic handbrake is used by drivers to lock up or break loose the rear wheels when they want to Drift the car sideways or spin on the spot. Rally drivers regularly need to spin 180 degrees "on the spot" when they over shoot an intersection, or need to turn very hard left or right and there's not enough wheel lock to achieve this. The hydraulic handbrake is not used to stop the car. A hydraulic hand brake can be added into the rear brake line system without changing the original mechanical handbrake setup.
