1995 Buick Riviera Bleeding brakes

Find the brake bleader fitting, it looks like a grease fitting. then put the wrench on it and put a rubber hose over it and submerge the other end into a clear container of brake fluid and turn the car on and have a friend apply pressure on the brake and loosen the fitting, then release brake pressure. then depress the pedal and repeat untill no more air bubbles appear in the fluid filled bottle, repeat this at all four tires.
