I don't know. I wasn't there. I never keep my fluids at the max level and it was filled to max. There are no leaks anywhere in the brake system. I'm gonna flush it again and probably pull the calipers and clean them out. It's getting better each day..

 

If you look in your owners manual...it tells you to have the brake system serviced, Forget what milage...if you didn't do this it will not be covered under waranty. SOL

 

It was serviced as I just bought 8 months ago and it is a Ford Certified Pre-owned Vehicle. They have to service everything including replace tires and brake pads.
