Review on 🔧 8milelake Pneumatic Brake Fluid Bleeder Tool with 4 Master Cylinder Adapters, 90-120 PSI - Ultimate Solution for Efficient Brake System Maintenance by Mysocalled Gaultier

I used about 90psi of pressure to run this. Well sucked. This will worry you a little as you will see a lot of air coming out, but it is coming through the threads and not out of the system. I stopped the suction every 30 seconds without tightening the screw (make sure the hose is over the outlet valve) and refilled the reservoir with fresh liquid. It also allowed some of the liquid to go into the hose so I could tell when the liquid was clear and I could prevent the wheel from bleeding/flushing. In general, the work was greatly simplified and did not require the involvement of another person. The kit includes a bottle that makes refilling easier as it has a shut-off valve. You can also open the valve and put the end in the tank so you don't have to keep an eye on the level, but I didn't mind doing that part by hand.
