They have a separate brake.We will need your loom serial number. Find your serial number here:Baby Wolf: Serial numbers are pressed into the wood and can be hard to see. A flashlight held to the side and shining across the numbers (not directly on them) will help.The serial number can be found underneath the Schacht logo on the cross piece under the harnesses at the front of the loom.On older baby wolf looms, the serial number may be on the castle side. If you added a high castle tray, you may need to remove the tray to find the serial number. Mighty Wolf: The serial number can be found underneath the Schacht logo on the cross piece under the harnesses at the front of the loom
