    Can this be done in place of a traditional flush or would you still need to flush the old school way to get fresh fluid?

    I think this is only for getting the fluid out of the abs module. For the brakes themselves you'd likely need to do a normal flush. I've only heard about this so I'm not sure.

    Have you gotten some air in the system or just want to clean it out?

    There's no return lines from the calipers so there's no way to flush them other than manually. INPA thingy is for ABS/DSC/Master cylinder shenanigans AFAIK.

    My understanding is that running the bleed procedure for the ABS/DSC pump is for when the pump is replaced and or the fluid has been depleted. To vibrate any air bubbles free of the valves or anywhere else they are sticking so they can make their way to the calipers to be bled out.

    Thanks for replies. Thought I could be slick.
