I recently had those exact symptoms, and replacing the master cylinder 
did the trick. And remember, you'll have to bleed the air out of the 
slave at the back when you install it, and again after several hundred 
miles. Conventional wisdom says that the slave fails after the master 
is replaced, but whether it does or doesn't you may have to bleed twice 
so don't stray too far from your garage until that second bleeding.
