Can someone please verify if the 716/718 Brake Booster should have a rubber boot over the end that is inside the pedal casing?
The Spare Parts Diagram shown here does not show a rubber boot:

......but the drawing of the booster in this page does suggest that it has one:

The 710/712 Brake Booster definitely has a rubber boot (Part 4):
