Why does the brake pedal go all the way to the floor?

Hello, either there is still some air in the lines that needs to be bled -- including performing an ABS system service bleed -- or the master cylinder could be impacted by fluid backing into the brake system when servicing the system. I'd lean towards air still being in the lines based off of the repairs performed. Use this link to find some shops near you that can help with your concern: www.repairpal.com/repair-shops
