The pneumatic brake bleed kit provides easy operation for one person using standard air power (90-120 psi / 6-8 bar). It works quickly, efficiently and unbeatably, without the need for specialized attachments. It allows the brake system to be bleed directly through a coupler and allows for a complete fluid change in the brake system. The set does not require additional equipment. Usufruct: 1. Make sure the hoses are tightly connected to the appropriate connectors. 2. Connect the kit to an air power source with the correct pressure (90-120 psi / 6-8 bar). Make sure the hose is properly connected and there are no air leaks. 3. Once you have found the vent point, place the end of the kit on the vent. Then use the trigger or lever on the kit to start bleeding.  4. When bleeding, observe the brake fluid in the clear brake fluid tube or reservoir to ensure it is clean and free of air bubbles. 5. Repeat this process for each bleed point in the brake system, starting at the point furthest from the brake fluid reservoir and ending at the point closest to the reservoir. 6. When bleeding is complete, make sure the brake fluid level in the tank is adequate. Add liquid as needed. 7. After bleeding is complete, test the brakes to make sure they are working properly. Important! 1. Always follow the recommended air pressure range (90-120 psi / 6-8 bar). Using too much pressure can damage the braking system. 2. When working with the kit, make sure the work area is well ventilated. The air coming out of the brake system may contain harmful fumes. 3. Brake fluid may cause skin irritation and damage clothing. In case of contact with liquid, rinse the skin immediately with water and remove contaminated clothing. 4. Before each use, check the condition of the kit, including hoses, fittings, and connectors to ensure there is no damage or air leakage. 5. Keep out of reach of children and pets.
