Rear brake wheel cylinders

Was bleeding the brakes on my 61' AH Sprite and noticed that the rear wheel brake cylinders actually move abit (1/8-2/8 inch, view from under axle, of course) in that rectangular opening they sit in when the brake pedal is depressed. Is that normal?

The cylinders look logically installed, lever hooked up correctly. The cylinders do not completely fill in the rectangular opening in the (wheel housing, for lack of knowing name) like the front brake cylinders do. Comments appreciated as usual...Irish
 
Irish... you'll note that the rear of the cylinder, the end without the psiton also contacts the shoe. When the brakes are applied, the piston pushes on the one shoe, then the cylinder is forced in the other direction pushing on the other shoe. Beautifully simple as long as the cyliner does slide.
