This brake fluid extracting system is the easiest way to bleed brakes by yourself if you don't have an air compressor. Start by creating vacuum in the 19 1/2" tall container by pumping the unit about ten times. Then push the red rubber fitting (on the end of the 61" clear extracting tube) over the bleeder screw, open the bleeder screw, and watch the dirty fluid get sucked out. It doesn't get any simpler! A special reservoir refill bottle is included to maintain a constant level of clean brake fluid in the master brake reservoir. When you start to see clean fluid come through the clear tube you know you're done. I recommend you use the extractor to suck out the dirty fluid from the master reservoir first, fill with fresh brake fluid, then start bleeding the brakes. Great for race tracks or areas without air compressors. The extractor tank holds 1.056 gallons of brake fluid! 19 1/2" tall. Imported.
