Which brakes are locked up, front, rear, one, both, all? Also, you never want the brake pedal to go more than halfway to the floor. Running it down more than that will usually damage the master cylinder. Even when bleeding the brakes with a helper, which no professionals do, you never want to push the pedal over halfway.
If you have a brake that's not releasing on the rear, the first thing to look for is a rusted and partially-applied parking brake cable. Ford has a huge problem with them rusting up in as little as a year. When they are just sluggish you can often get them to retract by flexing the casing at that rear wheel.
The next step is to disassemble the locked brake to see what came apart. It could be as simple as a brake shoe lining rusted off and is wedged between the drum and the other shoe. A shoe return spring could have rusted apart allowing the shoe to keep grabbing the drum. It's also pretty common for the adjuster cable to rust apart and the lower hook gets wedged between the drum and rear shoe. Most of the time locked rear brakes are not serious. Getting the drums off is the hardest part.
