A method for the operation a parking brake of a motor vehicle that comprises at least one wheel brake device, wherein the wheel brake device comprises an electric motor that can be activated for its actuation and that drives a spindle for the displacement of a brake piston between a clamping position and a release position, wherein for the calibration of the parking brake the electric motor is activated in order to move the brake piston into the release position in a first step and from the release position into the clamping position in a subsequent second step. It is provided that in the second step a power supply of the electric motor is interrupted during the displacement of the brake piston in a no-load phase (II) and at least one motor parameter of the electric motor is determined depending on a coasting behavior of the electric motor.
