Review on BikeMaster Vacuum Brake Fluid Bleeder by Joseph Cvetkovic

I used it to bleed the brakes and clutch on a motorcycle. The suction is adequate for a motorcycle but can be a little slow for a larger car bleed but still beats needing an extra person to bleed the brakes. Pressurized bleeders are much faster, but for casual use this works well. When venting, open the vent valve half a turn. This allows air to enter and you will see bubbles in the liquid that is drawn out. If you see liquid and bubbles together, it's time to stop and perform regular air purges to ensure all air is removed. In general, it's worth the money and speeds up work.
