How do you bleed the brake system on a 2000 gmc safari van?

To bleed the brake system on a 2000 GMC Safari van, start by ensuring the brake fluid reservoir is full. Begin at the wheel farthest from the master cylinder (the right rear), loosening the bleeder valve and having an assistant press the brake pedal. Once fluid flows without air bubbles, tighten the valve, then move to the left rear, right front, and finally left front brake in that order. Check the brake fluid level frequently and top off as needed during the process.
