I guess thats a new way to do it. As I see it, it's all about money.
With out the nippled fittings, two pieces of hose, and the clip to hold the hoses down in the reservoir, the kit would involve less parts.
I saved the accessory parts from one of the MC's a long time ago just in case I needed to re-bleed one or a used MC from the bone yard. The new procedure makes sense and I guess I could toss the bleed kit and make room in the tool box for other clutter!
