Have a 2017 grand cherokee about 30k miles. While slowing off the highway to a stop, no problems. Smooth as silk. After slow driving for a little bit, when slowing from 10 to 0, I get a thump thump thump, mainly after I press harder, harder, harder but not slamming the brakes on.
Now, it sounds to me like a deep sounding squeak as if the pads are grabbing and sticking to the rotors, then when they let go I hear the squeak. It feels and sounds like when you have a wet finger and slide it across a balloon. It grabs the balloon then squeaks when it slides across it.
Dealer replaced the rotors and said the pads were fine. I went in again and it was a beautiful dry day and I couldn't get it to re-occur. After the recent snow, it is happening a lot. The dealer where I bought it will fix for free but it is very inconvenient to get there from my home or office.
I can do things on my own but don't know what to do. Maybe replace the pads?
Any thoughts what might cause this?
Thanks in advance!
