1997 Pontiac Bonneville

Start at the furthest point from the master cylender (passanger side rear) and work to the closest (driver's side front). Have a helper pump the brakes at least 5 times and hold pressure on the brake pedal while you loosten the bleeder at one wheel at a time. When you open it, fluid or air will come out, the brake pedal will drop to the floor, and the helper needs to hold it there until you retighten the bleeder. Once tight, go through the process again until there is no air coming out.

Let me know if you have other questions.
