A pneumatic brake system (110) for a commercial vehicle (1) has one spring brake (27), a protection valve (56), a parking brake unit (30), a network of pipelines (40), at least a first (4) and a second (5) tank with compressed air and a relay valve (19) for the parking brake unit (30). A first subnetwork of pipelines (40a) comprises pipelines configured to be pressurized at all times. A second subnetwork of pipelines (40b) comprises at least one pipeline configured to be non-pressurized when the parking brake function is applied. The first subnetwork (40a) comprises pipelines establishing fluid communication between the tanks (4, 5) and the parking brake unit (30), wherein the direction of air flow in these pipelines is by at least one thereto associated valve (50). A method for managing an air flow to an air-actuated spring brake (27) of a pneumatic brake system (110) is disclosed.
