Dave - it will be a couple days before I have access to my pictures
, but I will do so. Patrick may be able to post the info on the can lid seals.

On the reservoir - the brakes and the clutch cylinders normally only pull fluid from the reservoir to compensate for lining and clutch wear - a slow process. You have separate master cylinders for front and rear brakes and the clutch. If you blow the seal completely out of the clutch master and lose all the brake fluid in the reservoir - your brake systems are still full of fluid and tight and will operate fine. There will even be some fluid left in the lines to the brake masters from the reservoir since there are three lines. You should have brakes until the linings wear some more or a seal leak in the brakes develops.
