- Open Brake Fluid Reservoir: Carefully open the brake fluid reservoir cap on your vehicle.

- Activate Equipment: Activate your brake fluid changer equipment. Allow the equipment to operate until brake fluid fills the lines and begins to discharge, confirming the connection is complete and the system is ready for bleeding.
