Brake fluid in power Steering

I just topped off the power steering reservoir with brake fluid in my 08 CC.
Sucked out as much as I could before starting the truck.
Do I need to do anything else besides learning to read?

Probably would be a good idea to flush the entire system... so do the steering rack as well - which will involve doing lock-to-lock steering (front end lifted off the ground) quite a few times. Even though both are hydraulic fluids the additives are different and brake fluid has the potential to damage the seals on the power steering system over a long period of exposure.

Thank you...
If I empty the reservoir and refill with fresh daily for a week or so, will that do the same thing, making sure to go lock to lock when I drive it.

Get the brake fluid out at the dealer or some other shop ASAP!.

Brake fluid is corrosive. I can't think of the name of the material used in brake systems but it is different than the softgoods in a power steering system.

This

The power steering system is made to handle the detergents of transmission fluid, not brake fluid. It'll literally eat the seals away.

Better than the other way around, at least this way you have time to get it out. If you put powersteering fluid in the brake reservoir the seals would already be bloated
