Question

Both technicians are correct. A bleeder screw wrench is indeed needed to open and close the bleeder valves on brake calipers or wheel cylinders during the manual bleeding process. Additionally, using a length of plastic hose and a clear jar helps to safely direct the old brake fluid out of the system while preventing air from being drawn back into the brake system during the bleeding process.
