Review on Efficient Brake System Maintenance: Introducing the Cardone 10-5000MCB Brake Master Cylinder Bleeder Tool by Johnathan Hegie

Works great! When installing a new MC I used it to bleed before installation. I pumped liquid into 2 ports for the lines, only had to do this 3 times for each port. Then I used the traditional route with lines running from the ports back to the reservoir to make sure I was out of air. And after 5 pumps I made sure there was no air. When I told myself that the napkin works, I heard that doing it the traditional way can take a long time, so this napkin really saves a lot of time and effort.
