haha. Well, first of all, it would probably take 60 seconds to set the bloody thing up in all them vices n shit. Then you have to bleed it, correctly, you would have to put atleast 3 seringes of fluid through to get all air out... And then you have to put back on bike, so i would say 20 mins atleast... I havnt had to bleed my brake for around 1 year now, and thats off a bath bleed, and its still AWESOME, no TPA needed at all, and is solid as f**k, best brake iv EVER had, and EVER used! as all my mates, and people i ride with.. say.
