Default Brake fluid flush

H3, 2007, 121k

So I went to GM service, he said 121k they can’t do it.
Too old, they wouldn’t be able to bust open the valves
to drain old fluid! I had no idea. So what do I do? I fluid look dark in the reservoir

The LAST place to take an out of warranty vehicle is a GM Service dealer. They are full of chit (too old is BS), charge too much, and you have no idea who at the stealership will actually do the simple work.

Go to a reputable local repair shop and talk with them. I can open bleeder valves on 50+ year old Oldsmobiles with zero issue.
