Ted, you DO know that Mike sells brakes and a bunch of other parts for our cars. He always is willing and eager to help the members get their brake problems solved. Sometimes he can even be a little or alot sarcastic, that's why we like him.
Most, but not all 348/409s leak a little or a lot at the rear main, all 4 of mine did, certainly there are some that don't, I'm just not aware. Mine now leaks just a drop or two after cruising, "almost" nothing.
