Caliper Adjust????

Can I adjust the pressure of the caliper on my 74 Dart Sport? I know NOTHING about these........

The drivers side caliper is just plain too tight............How can I adjust these to match from side to side????

...............AND, there seems to be a grease fitting on the calipers...(Like I said, I know NOTHING about disc brakes....sorry to sound like Sgt. Schultz, BUT....) What's the best shot for these? :read2:
