Replacing Master Cylinder

[eyerockz]

I about to change out the Master Cylinder on a 1998 Tahoe 4x4, I will bench bleed before installation, then bleed all 4 corners starting at the right rear. Do I need to also bleed the ABS module also, to remove the any air? Will I introduce air to the ABS module when I remove the hoses to the Master Cylinder?

Since the Master Cylinder is before the ABS module in sequence, you are more likely to get air in the ABS system. If you change the Master Cylinder, you're going to want to bleed the ABS module as well.

ABS can make this suck. I was never able to get the air out at the house. Needed to get the system vacuum bled.
