Larry, Ron: on my 93 coach the rear tank feeds the rear brakes and my service tank is in the front near the front brake tank. While the service tank could be positioned anywhere in the coach the brake tanks need to be close the brakes. When the brakes are applied it requires a lot of air right now supplied through large lines. It would be difficult to supply that air volume from the front of the coach to the brake valve in the back of the coach without an enormous line.

I recently worked on rear brakes and am confident in how mine is plumbed. Others coaches may vary.
