I've never heard of 'partially loaded' and I've been in the auto business for a while now...that's not to say it doesn't exist though.

A 'non loaded' caliper will not come with brake pads, where a 'loaded' caliper will.

Your first step here should be to find out exactly what is wrong with your car. 'Throwing' parts at a problem can get expensive very quickly and sometime it doesn't even fix what's wrong.

I have been taught and it is my experience that it is best, when replacing any component like that (brakes, shocks, bearings, ball joints, etc.) on a vehicle, to do both sides. You don't have to do this, but if one side went bad, chances are the other side isn't too far behind, and with brakes I don't like to gamble. In addition to this, if you are going to have a shop do the work, doing both sides at the same time can save you money on labor, over doing each side individually at different times.

Past that, there are many different setups on vehicles for the caliper mounting. The setup will also be different front to rear on your particular vehicle. My suggestion...talk to someone you know who knows what they are doing, and buy a Haynes or Chilton service manual. If you do plan to tackle the job, again, do it with someone who knows what they are doing.
Good luck. Let us know what you come up with. MM
