Here is the pneumatic pump in ACSUD Industry to bleed the brakes. This pump allows for the purge and one without difficulty. However, it should have a pressure source (compressor or other ...) sufficient for the use of the pump that plugs at the handle (fitting not included).
The operation is as follows: First you must fill the jar to the pump (1L capacity) of brake fluid, connect the hose with rubber tip on your caliper bleed screw in passing this hose features good length and is transparent allowing to properly control the passage of fluid. Then do not forget the connector on the handle to an air pressure system (thus a compressor). Then by the action of the handle with your hand, put pressure manually to "insert" the new brake fluid through the stirrup, pushing the liquid through the mud or brake fluid reservoir. Obviously should be emptied as a measure the waste liquid that you want to remove.
Clearly, a good tool for the right mechanic who wants to find ways of doing things alone and without worries. Unfortunately instructions provided in English.
