Claim:
1. A method for producing a combined service-brake and spring-loaded brake cylinder for a brake system of a vehicle, the combined service brake and spring-loaded brake cylinder including a selected storage spring and the brake system including remaining brake actuating elements, the remaining brake actuating elements being actuatable by the selected storage spring, the method comprising: a) determining, in different operating states of the brake system, force-actuation path characteristics of the remaining brake actuating elements; b) determining force-actuation path characteristics of candidate storage springs for potential use in the spring-loaded brake cylinder; c) determining a minimum required actuating stroke of a piston of the spring-loaded brake cylinder and a minimum required spring force for effecting a parking brake function via the spring-loaded brake cylinder by ascertaining points of intersection of the force-actuation path characteristics of the remaining brake actuating elements with the force-actuation path characteristics of the candidate storage springs; d) selecting, as the selected storage spring, one of the candidate storage springs that produces an actuating force sufficient to effect, for at least one of the different operating states and a given maximum vehicle mass, the parking brake function with the smallest possible actuating stroke; and e) producing the combined service-brake and spring-loaded brake cylinder including the selected storage spring, wherein the combined service-brake and spring-loaded brake cylinder dimensions based at least in part on the smallest possible actuating stroke of the piston of the spring-loaded brake cylinder.
