Hello, Volvo V40. Disc brake at the rear with integrated hand brake to install the new documents which has pressed the brake piston back by means of a reset. Principle: pressing the brake piston and screwing the brake piston in. Is there now a prescribed order after the installation of the new documents to drive the pistons back to the receipts and discs? I have repeatedly pressed the levers of the hand brake back and forth. Thus, the pistons have moved out piece by piece until they reach the Bel ege pressed firmly to the discs when pressing the hand brake lever. No pump was needed for the foot brake anymore, the brake responded immediately. Thank you for an answer mfg
