A method for operating a hydraulic brake system for a motor vehicle that includes a hydraulic brake system with a hydraulic unit, a brake fluid reservoir and hydraulically actuatable wheel brakes, wherein the hydraulic unit has a main pressure source which can be actuated via a brake pedal, an additional pressure source fluidically separate from the main pressure source, and control valves by which the main pressure source and the additional pressure source on one side and the wheel brakes on the other side are connected together, wherein in the brake fluid reservoir, multiple at least partially mutually separate reservoir chambers are provided for supplying the main pressure source and the additional pressure source with a brake fluid, wherein the method comprises detection of a fill level of the brake fluid in the brake fluid reservoir by a measurement assembly, wherein the detection of the fill level takes place in analog fashion.
