A method of detecting a leak in a brake-by-wire hydraulic brake system includes determining if the brake system is in an ABS cycle and determining a pressure medium volume delivered for a measured brake pressure when the brake system is in the ABS cycle. The pressure medium volume is compared with a model value for the brake system at the measured brake pressure. Wheel slip of at least one wheel is identified when a difference between the pressure medium volume and the model value exceeds a specified threshold. At least one brake is isolated corresponding to the at least one wheel without wheel slip.
