New pads squeal more than the old ones

CleanNerdCommunity StarterDec 7, 20252024 Kia EV9 GT-LineChicago
I replaced pads and rotors and now the brakes squeal at low speed even though stopping performance is good. Hardware was cleaned and lubricated. Is some noise normal during bedding or should I pull everything apart again? Any data points from owners would help.

Start with the test that can prove you wrong. Write temp, speed, and in-gear vs coast when the 2024 Kia EV9 does it — then decide on parts. Save the big job until that test fails. Time, temperature, and whether it's in gear are the notes that actually help a shop. Worth doing even if the car feels fine right now. Wrote this up on my lunch break.

If it were in my driveway, a pressure test beats staring at a dry driveway if the 2024 Kia EV9 is losing coolant with no puddle. That's the branch I'd chase this week. Did the worksheet show tax yet? That's my plan before I call anyone.

I'd want a measurement, not a hunch. Capture voltage while the 2024 Kia EV9 is actually failing — after it restarts you've lost the clue. Save the big job until that test fails. If you share a photo of the worksheet, easier to sanity-check. I'd rather be boring and correct. I'm keeping receipts and dates in one folder.

Log the conditions before you spend. Write temp, speed, and in-gear vs coast when the 2024 Kia EV9 does it — then decide on parts. Don't erase codes until someone who can help has seen them. On “new pads squeal more than the old,” that was the fork that mattered for me. The universe charges extra for guessing. Happens in gear, not in park, for what that's worth.
