RE: Backing plates and grease. I wouldn't think backing plates could cause the condition unless they were so rusted through that they've lost their structural integrity. I would expect your mechanic to note that and not do any work on the system until the plate or plates were replaced.

A small amount of grease is usually placed at the top and bottom edges (or toe and heel) of the metal shoe where it slides along the backing plate. These areas are an inch or less in length so a very small dab of grease is sufficient. Usually, you can see a mark on the plate in those areas. If those areas are deeply worn, the mechanic should recommend plate replacement.

With the comment that the master cylinder was full of "jelly" I'm suspecting the lines and hoses to be likewise. The lines may have enough moisture in them to be rusting through from the inside out. They need to be carefully checked.
