2017 Hyundai Elantra — brake fluid is old but still looks clean

Thanks — that narrowed it. I'm going to try the simpler check on the 2017 Hyundai Elantra first. Wrote this up on my lunch break.

Don't overfit one forum story to your car. If it still isn't clear on the 2017 Hyundai Elantra, a specialist hour can be cheaper than another round of parts. Then you'll know the next fork. Do that first. That's coming from doing this as an owner, not a shop. I'm keeping receipts and dates in one folder.

Write down what you already tried. A second data point from another 2017 Hyundai Elantra owner helps more than a generic diagnosis. I'd do that before spending real money. Had a similar mess a couple years ago and that's what finally sorted it. Might be overthinking it, but I'd rather overthink than overspend.
