Are your emergency brakes in the rotor, these often get overlooked. They can fall to pieces after awhile,give them a look.
Need help diagnosing growling noise
Hi, I'm at my wits end. I have a growling noise coming from the back left area. At first I thought maybe it was worn tires, so I got new tires. The noise is still there. Drove a couple thousand miles, rotated the tires, noise stayed the same. I did all the tests for a wheel bearing (shaking the tire side to side, rotating and listening and feeling for noise, used a mechanic's stethoscope all around the hub/bearing area). The only thing that makes it sound like a wheel bearing was the noise got louder up to around 60mph, then a little quieter when going faster. The noise gets lower pitched and more grinding sounding when turning right.
But I just replaced the wheel bearing and the noise is still there. I looked at the rotor dust cover, the brake pads, all looks normal and I don't see anything dragging. The caliper clears the wheel rim.
Does anyone have any idea what this noise could be? I can't remember if the noise showed up before or after I had a shop replace the pads and rotors a year ago. Could that be the source? Something in the pads or rotor?

Is there a separate pad for the emergency brake? I did notice the interior part of the rotor is not gripping on the outside edges. Are you saying pieces of it could have fallen into the rotor?Are your emergency brakes in the rotor, these often get overlooked. They can fall to pieces after awhile,give them a look.
My bad , I just looked and it was not how I thought . Sorry for that.
Depending on year and make of your truck, it may e-brake shoes inside of
the drum with rear disc brakes. Look under your truck and see if there is a
cable going to the backing plate on both sides. If there is a cable, then you
have mechanical e-brakes. These brakes were notorious for rusting the
lining off of the metal part of the shoes.

No problem, I appreciate the response!My bad , I just looked and it was not how I thought . Sorry for that.
I have a cable running to the caliper for the ebrake, it's a 2017 Grand Caravan. Will take a look at it next time I have a chance to jack it up. Thanks!Depending on year and make of your truck, it may e-brake shoes inside of
