Need help Brake Bleeding problem

[Ford Man]

If you're losing any brake fluid you may have a leaking wheel cylinder. When you were bleeding the brake lines were you keeping the fluid reservoir topped off? If not it could have gotten low enough that it sucked more air into the system. You should refill the reservoir after bleeding each wheel to be sure it stays at a level full enough not to pull more air in. There could also be a leaking brake line either rusted through or leaking at a connection.
