To bleed disc brakes on a bicycle, follow these steps to ensure optimal performance and safety:

1. Gather the necessary tools and materials, including a bleed kit specific to your brake system.
2. Remove the wheel and brake pads to access the caliper and brake fluid reservoir.
3. Attach the bleed kit to the caliper and reservoir, ensuring a tight seal.
4. Open the bleed port on the caliper and reservoir, and slowly pump the brake lever to push out old fluid and air bubbles.
5. Refill the reservoir with fresh brake fluid as needed, and continue pumping the lever until no air bubbles are present.
