Start at the wheel furthest away from the master cylinder. You will need a helper for this process. With the engine off, have a helper pump the brakes 4 or 5 times. At that point, he must keep pressure on the brake pedal. You then open the bleeder valve and air or brake fluid will come out. NOTE: Tell the helper that the brake pedal will go to the floor, and he must hold it there until you tighten the bleeder. Do that over and over till there is no air coming out. Then move to the next wheel until they are all done.

NOTE: Make sure to keep the master cylinder full of brake fluid at all times. It will drain quickly when you do this. If you allow it to go empty, then you will need to bleed the master cylinder.
