Pretty much. If you havent had the calipers off to check the condition of the pistons and seals you best have a look and be prepared to order a rebuild kit, or order one anyway as chances are you will need it at some point before long. If you get someone to slowly press the brake pedal once you have the caliper off you can get the piston out a bit more to check the condition and then wind it back in with a rewind tool. Or rebuild them and your good for a while. Its always good to get the piston wound right out then wind it right back in as just under normal braking and the hand brake the piston only ever moves a tiny amount so they can seize.
When its back together remember to pump the brake pedal a good few times until its nice and hard before using the handbrake or driving the car, saves a suprise at the first junction!
