worn out brakes will cause this allowing the pistons not to return to correct adjustment.loose parts inside brake drum from will also cause this so if you inspect rear brakes with brake drum removed and this is not the problem, your master cylander is bad and not allowing fluid to return to resevoirr, therefor still keeping brakes expanded if this is the problem the it will get worse each time u use brakesuntill they stay locked up and you cannot move vehicle get brakes checked yesterday
