Via a method for venting at least one brake channel in a brake circuit of a compressed-air brake system of a vehicle, the brake channel can be vented. The compressed-air brake system has a brake pressure modulator that includes switchable valves for a control pressure. The brake system has an electronic control device interacting with the modulator. The modulator has, for each brake channel, at least one relay valve via which, firstly, a quantity of air can be introduced into at least one brake cylinder for actuating the brake and, secondly, the brake cylinder can be vented. During the venting operation, an adjustment to a setpoint pressure target is implemented. A setpoint pressure gradient during the venting operation is changed, in a manner dependent upon the pressure in the brake cylinder and on the operating state of the vehicle, in accordance with an algorithm stored in the control unit.
