Is my rear master cylinder shot?

I changed the lines on my brakes and then bled them using a vacuum pump. The rear will not build pressure and when the vacuum is applied at the bleeder, the reservoir drains without the brake being applied.

Because of this, it seems to me that a seal in the master cylinder would be blown allowing fluid past it regardless of the position of the brake.

What say you?

Thanks in advance.
