Not the thump thump noise but the whir whir noise.Sounds like maybe the rotor is hitting the caliper or bracket.
Had the same exact issue recently with PowerStop rotors. Took quite a while to narrow down the noise because once the wheel is off and the rotors aren't "torqued" to the hub the noise goes away. I definitely used quite a few choice words while troubleshooting the issue, lol.There seems to be a lot of issues with rear rotors not fitting right on our cars. I see it a lot on Facebook, as well as my experience as well.
I got some used cross drilled rotors a while back for super cheap but had to spend a considerable time trying to identify why they were grinding (or whir whirring) on the backing plate. I eventually grinded down the backing plate or dust shield closest to the rotor, I used an angle grinder with a flap wheel. I haven't had the noise since.
In your case though, it might be the internal parking brake hardware inside the rotor.
Might be the parking brake hardware. I messed up in not turning the star adjuster and just released the parking brake when taking the rear rotors off.There seems to be a lot of issues with rear rotors not fitting right on our cars. I see it a lot on Facebook, as well as my experience as well.
