Get some sort of sucker like a turkey baster and suck all the fluid out of the master cylinder, then fill with whatever fluid you want. Then get a buddy to help you push the brake pedal a few times, then go to the right rear wheel and loose the bleeder screw on the caliper about half a turn to a turn, fluid will squirt out. Keep doin that a few times and then move to the left rear wheel then right front then left front. Keep an eye on the fluid level in the master cylinder cause if u run dry, air will get in the system and thats no bueno. Since the clutch hydraulic system uses the same fluid the brakes use, you gotta bleed your clutch too which is a total pain in the asshole. I'd try to explain it but the pictures in the FSM show you better.

You can buy a vacuum pump at Autozone and bleed them yourself. Very very easy to do.
