PITA
My biggest fear is the master cylinder failure when bleeding. My brake pedal in both my cars has never seen more than the top 25% of travel. Once you manually bleed with the pedal, the seals in the master cylinder go deep into the previously unused 75% of the cylinder that may be a smaller diameter and could be filled with debris from years of service.

I am getting ready for a BBK on my E46 with an original master cylinder so I bought a Motiv pressure bleeding tank to try to avoid shoving the master cylinder seals into the abyss.

This should also help in the INPA ABS pump bleed without having to pump the pedal to move the fluid through once the pump runs. Fingers crossed.
