Rear Brake Squealing Already?

I rebuilt the entire rear end on my 88 trx 300a 2×4. I walnut shelled blasted the rear brake plate, installed a new bearing, Cleaned and installed the cam shaft with anti sieze, new seal and felt. New shoes installed. All in Oct 2014.

I rode it last hunting season, then 1 work weekend at the lease in february this yr. May 1 weekend the rear brake is squaling like its metal to metal?

Do they not last longer than that?
