Ranger Brake Trouble

I’m having trouble with the brakes on my 1985 Ford Ranger. When I step on them and then let up on them, the brake pedal does not return to its original position, and the brakes do not release. I can put my toe of my shoe under the pedal and pull the pedal up which releases them. Does anyone know what causes this?

This could be coming from a few things. Maybe your master cylinder, booster or a mechanical issue with your pedal. No way to know without seeing it. Have it looked at, sounds dangerous.
