2007 RAV4 brakes - fixed for sure?

Update: So, I got the MC replaced (and tranny fluid changed, and 60,000 mile checkup). Brakes seem a bit better - surer. Or it could be my imagination. At any rate, it’s done and I don’t have to worry if I have a marginal master cylinder. I’d rather have a car that can’t go, than can’t stop.

Cheers,
Banty
