I read somewhere that in order to do a proper bleed for the brake system, one needs to connect a diagnostic computer to run the ABS DSC pump in order to ensure that there will be absolutely no air bubbles in the system. Theoretically all the shops do this on a total system bleed. Does anyone know if this is true? Has anyone done steel lines then subsequently bled the system and found no air in the system?
I just did a bleed myself from factory fluid to Castrol SRT, so it was not a full system bleed. That being said, both of my front calipers had air in the brake lines right as I started bleeding them...
has anyone seen this?
