Challenger SRT Hellcat
Possible, you may have had a brake caliper piston sticking a little. Mine sounded like that a couple of times when coming to a slow stop, but only a few times.A few weeks ago I posted about a thump or clunk noise that would happen whenever I went lower than 5mph to a stop. Hard or soft stop it didn't matter but it did the noise but not all the time.
Suddenly since yesterday afternoon and all day today driving it went away.
Service manager at my dealership said it could be the transmission shifting down but to let her know if it got worse or did it more often.
Shrugs my shoulder but problem is gone.
