Jack the car up and try spinning the wheels by hand. Are you saying the brakes are stuck on, and the wheels won't spin free even with the car jack up?
If so, something is sticking in the front brakes. It could be a seized brake piston, or seized slider, or brake pads are stick to the holder somehow.
Either way, it's best to take the whole brake off, and dissasemble the caliper. You will know soon enough if the piston is stuck in the bore.
Clean everything with brake cleaner. Only use rubber grease, not wheel bearing grease.
