W211 320CDI Brake pusating while driving

Hi ! Have this lovely W211 E320CDI with the OM648.- lovely machine! But ! I have this pretty annoying problem going on. Whike driving the brake on the rear left is activating (pulsating very quickly)and the SBC pump is running. I have changed the rear wheel speed sensors and the magnetic rings. But no change. There is no fault codes stored in memory. Have anyone tried something like this ?
