Hayes Nine front and rear hydraulic disc brake levers and calipers. 295g front, 310g rear.

These brakes may need a bleed (they use widely available D.o.T. 3 or 4), though that is based on general principal rather than anything specific to these brakes. The levers have some trail cred. (that is, some scuffing and scratching) and the hoses have some solid chowder marks (visible in the photo). All heads and threads are clean, lever action is smooth, oxidation is minimal, pads appear to have life.
