An anti-locking brake system has a damping cartridge (DC, fig 1) in a valve block B between a pump P and a low-pressure accumulator LPA. The damping cartridge comprises an elongated hollow seat 102 with a shoulder 122, an integrated pressure retention valve and a plurality of damping membranes 101. Each damping membrane is provided at extremities with two deformable cups (110, fig 6) with rims 111. The damping membranes 101 have the rims 111 pressed against each other between either two pressing rings 100 or between the shoulder 122 and a pressing ring 100, as to enclose radially placed air bellows a. When the pressure retention valve opens the fluid path between the low pressure accumulator (LPA) and the pump (P), the air bellows, a, act as cushions, absorbing and dissipating the induced pulsations. An embodiment is disclosed with additional air bellows, fig 9.
