Steelman Pneumatic Brake Fluid Extractor Kit features an air-operated brake fluid extractor with an automatic refilling design for fast, clean, and easy operation. The extractor's new safety design allows its air inlet to shut off automatically when fluid reaches the maximum level, and this air-operated unit won't cause electric sparks, making it safe for work environments. This kit includes a 2-liter extractor bottle and 1-liter fill bottle, both with a head assembly, as well as a series of hoses and a 16-piece bleeder screw set.
