What tools are used to bleed breaks?

Usually, a small box wrench that fits the bleeder, a hose that fits the nipple on the bleeder and container for the spent fluid. Then you need someone to pump the brakes for you and refill the fluid level with fresh fluid. Pump-up the brakes, hold the pedal down and slowly open the bleeder and run fluid into the container (I use a plastic pop bottle). When the brake pedal gets low, close the bleeder & pump up the brakes and keep doing it until you get air bubbles and then no bubbles. Don't forget to keep the fluid level full. If it empties it will suck air ad you will have to bleed the entire system including the master cylinder.
