Rear Brake Line "Tree" Removal from axle

How do you remove the brake line distribution tree from the rear axle?

its been a while but most of them are held on by a bolt right through the top of it, just unbolt. i think it has the axle vent on top of it, thats why you don't see it, remove the vent hose, and then you'll see that piece gets unscrewed that the hose was on.

Duh. I see the nut on the vent hose now. Thanks.
