start by taking the cap off of the resevoir and make sure it is full and be carefull to watch the level of fluid thro the hole process haveing 2 people makes the alot easier. You pump the pedal or lever 4 or 5 times then hold it in and on the caliper there is a little usually 8mm fitting that looks like a grease zurk that you unscrew (making sure not to release the lever/pedal. let out all of the air then tighten the bolt back up and pump the pedal 4-5 times again and do it over and over untill the brakes are where you like them to be.
