2018 Toyota Camry — brake fluid is old but still looks clean

Write down what you already tried. A second data point from another 2018 Toyota Camry owner helps more than a generic diagnosis. Then you'll know the next fork. Verbal 'we'll take care of it' is not a plan. Might be overthinking it, but I'd rather overthink than overspend.

Don't overfit one forum story to your car. If it still isn't clear on the 2018 Toyota Camry, a specialist hour can be cheaper than another round of parts. I'd do that before spending real money. Keep sale price, fees, and rate as three different conversations. If the story changes I'll post the new data.

Owner notes beat generic advice here. On the 2018 Toyota Camry in North Jersey, I'd fix the thing you'll notice every day before chasing spec-sheet extras. That's where I'd start. On “brake fluid is old but still looks,” that was the fork that mattered for me. Verbal 'we'll take care of it' is not a plan. That's my plan before I call anyone.
