MG Midget and Sprite Technical - 1275 rear brake cylinder gaiter

I have noticed that recent replacement 1275 rear brake slave cylinders may have larger dia outer rubber gaiters - On both my cars the back of the hub flange has broken through the rubber and on one side has totally demolished the gaiter - Has anyone else had this problem and is it possible to buy a slimmer gaiter separately ?

John,
I had this problem when my slave cylinder was not mounted rigidly enough to the back plate. As soon as I tapped the pin hole and used a screw to mount it, the problem went away.

It possibly sounds to me as though the brake cylnder is not remaining square insde the drum.

Thank you David & Robert - I agree that the slave is probably not square as only one rubber is being attacked - I have already replaced the circlip with a tapped hole - Having considered what may have moved the cylinder I have been advised that the fit of my shoes may be incorrect - During the rebuild I have followed the drawing in the Graham Bristow book "Restoring Sprites & midgets" page 52 - Could someone confirm that the illustration is wrong as I now think that the flat "lead" on the shoe should be first in the rotation of the wheel ?
