I have an 09 touring sport. (Modded)
My (red)brake,(amber) ABS, (amber)VDC, (amber)TRAC CONTROL
Lights all came on so I concluded (correctly) than by brake fluid is low.

Here is the problem, I put brake fluid in my power steering reservoir (oops!) and drove around a week wondering if it was time for a new master cylinder. (Cause the lights stayed on (doh!).

I know brake fluid is nasty caustic stuff and worry it has damaged my steering mechanisms.

Three questions:
1. Will a steering fluid flush at brakes plus (using valvoline synthetic) sufficiently remove the brake fluid or do I need a more involved process?

2. What damage should I look for?

3. Can you guys please go gently on me for being such a bonehead? (That's more of a request than a question I suppose lol)

4. (Bonus question) What am I forgetting.

Thanks in advance for your input. When I looked over at the HUGE brake fluid label on the cover my heart almost exploded knowing I'd driven a few hundred miles with brake fluid in my steering rack!!!!
