The traditional way of bleeding brakes is one person on the pedal and the other opening and closing the bleed screw until the air has gone, accompanied with them calling to each other. With something like an Eezibleed you use a tyre and reservoir connected to the master cylinder to pressurise the whole system. That way it only takes one person. Following advice on BlatChat I also discovered there's a way of avoiding the traditional gush of fluid over you and the paintwork when it goes wrong. I also use a non-return valve at the drain end, but that isn't essential. Jonathan (And happy to lend my kit) PS: There are negative pressure systems that suck at the bleed end and also allow you to do the job solo.
