Both are sticking or both were replaced? If front and rear are dragging, that would be typical of brake fluid contaminated with petroleum product, but that takes about a week to show up. It is more likely there is a minor mechanical issue. First I would look at a sticking parking brake cable. That will cause only one rear brake to lock up and in only one direction. If you ignore it long enough, the problem will seem to go away after the linings wear down a little. A sticking / partially applied cable also causes easy rear wheel lockup under light braking. At three years old, it's really too soon to have rusty parking brake cables, but the main cable could be adjusted too tight.
The rear shoes on either or both sides could be over-adjusted too. Here again, that will go away as the linings wear down.
A real common mistake that novices and beginning mechanics make is mixing up the rear shoes. The shoe with the shorter lining goes toward the front of the vehicle, and the longer lining goes toward the rear. Logic says that's backwards, but the rear shoe does most of the stopping. The front shoe's job is only to help apply the rear shoe.
There are a few other things that can cause sticking brakes, but none of them are suspect on a three-year-old vehicle.
