Abstract: In a method for detecting an incorrect installation of brake lines of a brake system for a multi-axle motor vehicle, a tandem brake master cylinder, connected by the brake lines to primary and secondary circuits of the brake system, is actuated to completely fill a primary reservoir of a primary circuit and a secondary reservoir of a secondary circuit of the brake system. The primary and secondary circuits are associated to wheel brakes of a first and second axles, respectively, and provide brake fluid volumes, of which the primary circuit is greater. Outlet valves of the primary and secondary circuits are then closed, and actuation of the tandem brake master cylinder is still maintained to thereby decelerate a revolving wheel of the first axle and determine a braking behavior. A measuring device indicates whether the brake lines are correctly or incorrectly installed as a function of the braking behavior.
