Abstract: A brake actuation system of a hydraulic brake system, for actuating at least one front axle brake circuit having at least one front wheel brake, and for actuating at least one rear axle brake circuit having at least one rear wheel brake, the brake actuation system including at least one hand brake module which, when actuated, can activate both brake circuits. In order to provide an improved brake actuation system with a plurality of actuation capabilities, which system can also be utilized in light motorcycles and scooters without the restrictions of existing brake actuation systems, while simultaneously offering a simple concept and a reduced cost and weight, the hand brake module is hydraulically coupled into a combined hand brake module, the combined hand brake module being designed to simultaneously generate brake pressure in both brake circuits.
