Features 1. Pneumatic brake fluid bleeder set designed to empty or fill the master cylinder and other fluid reservoirs, draw brake fluid from the reservoir, add new fluid, and flush brake fluid at the calipers. Can be used to pump fluid through the fill hole on the side of the gearbox, fill the transfer case and differential, and deliver high-viscosity fluids. 2. Allows single-person operation, saving time and effort. Ideal for draining oil, removing air, pumping, and carbon cleaning. Suitable for extracting or replacing engine oil or lubricating oil in ATVs, boats, and agricultural equipment. Applicable to industrial gearboxes, automobiles, motorcycles, and recreational vehicles. 3. Brake cylinder evacuation system connects via hose to create negative pressure in the reservoir to remove waste fluid while adding new fluid. Air pump operating pressure should be maintained at 68 bar. 4. Oil and gas separation system ensures strong pressure, fast oil transfer, rapid air removal, and efficient vehicle maintenance. Large-capacity pump suitable for various automotive repair applications. 5. Includes multiple connectors for extracting brake fluid, power steering fluid, antifreeze, and low-corrosion liquids such as combustion chamber cleaning solution.
