Abstract

A method for determining a state of a brake lining on a wheel brake of a brake system of a motor vehicle is disclosed. The wheel brake has an electromechanical brake actuator which is designed to build up a force, such as a braking force, acting on a brake disc of the brake system by pressing the brake lining against the brake disc, and which is assigned to a first axle of the motor vehicle. The method comprises the steps of: detecting a first wheel rotation rate and/or first wheel speed of the first motor-vehicle axle assigned to the electromechanical brake actuator; detecting a second wheel rotation rate and/or first wheel speed of the second motor-vehicle axle; and determining the state of the brake lining on the basis of the first and second wheel rotation rate and/or wheel speed. A method for operating a brake system of a motor vehicle, a computer program product, a control unit and a vehicle brake system are also disclosed.
