Review on 🔧 HFS Brake Bleeder & Vacuum Pump Test Tuner Tool Kit with Dual Functionality by Victor Correa

I haven't been able to get this alone to draw out much liquid. Even though it only holds a vacuum, when I open the release valve I only get a stream of bubbles at the beginning of the hose, even though there is no air in the line. Air can be drawn in through a loose connection on the exhaust valve and tube, or somehow around the back of the exhaust valve. I may need a different adapter to hold the exhaust valve tighter, but that defeats the purpose of the kit. In any case, it is impossible to determine when a clear liquid is passing. Coupled with a brake pedal assist, it's a working system, but no better than a cheap hose and bottle. I accidentally got air in the clutch line and sucking the air in helped a lot, but the bladder problem was still there.
