Bleed device (10) for hydraulic circuits (2), particularly for brake circuits, comprising
- a plug designed to be fitted with its first end (13) closing an aperture (3) of the said circuit, and
- a bleed duct (12) extending in the said plug and comprising a one-way check valve (26) which is normally closed with respect to the exterior of the said circuit and can be opened independently of the removal or slackening of the said plug in the said aperture,
- said plug comprising, at a second end (15) opposite the said first end, quick-release connection means capable of forming a coupling with the quick-release counter-means of a quick-release connector (43), for connecting the said bleed duct to a bleed liquid collection vessel (40a) and for the simultaneous opening of the said valve, characterised in that
- said quick-release connection means are additionally designed to receive a protective cap (19) of the said plug.
Kit for bleeding hydraulic circuits, of the type including at least one bleed device according to one or more of the preceding claims, the said kit including a quick-release connector which comprises a rod (46a) acting on the said obturator to open the said one-way valve when the said quick-release connecting means and counter-means are in the condition of being coupled to each other.
