There is no adjustment on a hydraulic disc brake - they are inherently self-adjusting and the pads should be very lightly rubbing the disc in normal operation.
However, the brake caliper can stick or get "cocked" on it's slide-pins causing the pad on one side to drag excessively. This can be caused by a bent pin, bad rubber bushings, bad or old lubricant on the pins.
You need to to remove the brake assembly and make sure the caliper slides on it's pins - a certain amount of drag is normal but the caliper shouldn't be jammed. They are exactly like the brakes on a car; but if you haven't worked on brakes before, you might want to find someone who has for help or pointers. The biggest tip being: don't apply the brakes when the caliper is off the disc unless there is something between the pads!

I would have preferred to edit previous post, but I didn't see a button for it.
