I accidentally added about 2 oz.'s of brake fluid to the power steering reservoir in my car. My mechanic said it would not hurt it, is he right?
It probably won’t but I’m not a gambler either. Sounds like a good time to drain and replace the power steering fluid.
Brake fluid is a glycol-ether based fluid.
Where with power steering fluid it’s a mineral oil based fluid.
So the seals in the power steering system might not tolerate the brake fluid.
Get the power steering system flushed before possible damage occurs.
