This is not the same miracle tool if it is practical ...

I admit I was expecting a lot of this tool ...
The concept attracted me a lot. Aspire only the Lockheed caliper side without having to enter (dirty most of the time) in the car to pump the pedal while another colleague handles the bleed screw attracted me.

BUT, because there is a BUT, once we slightly unscrewed the vent screw on the bracket, the screw is not tight. This has the effect of producing a continuous stream of air bubbles in the suction pipes once the assembly placed in depression by the pump. Of course, this does not inject air into the circuit, but it is then totally impossible to know if there is still air in the system!
I tried to "butter" threads with grease (to complete the seal), I even tried to manufacture rubber washers to surround the vent screw and sealing: nothing worked ...
The only solution Lockheed suck more than necessary and wait a few moments after reset to "0 pressure" to let slip past the bubbles and be almost certain to have them all eliminated. That's what I did when I mounted my aviation hoses and it has finally no problem. Fortunately, I had a 5L Tin dot4 at my disposal. But I have to relativize for the complete emptying of the circuit, I had to use ~ 75cl!

That said, the fault generated is not attributable to the tool itself but the general design of brake systems which are all made in the same way. Certainly with traps models "grow" the Lockheed since the expansion vessel, this phenomenon does not appear ...

To:
- Practical (implementation ease and we clearly see the quantity and quality of the product sucked)

Against:
- No instructions.
- Permanent air bubbles in the pipe.
- The Lockheed who eventually capillarity to move the jar next to the pump hose and into the pump!
