I finally got the video to work where I could hear it. What a funky goose honk.
Look at your rotors for rust in the mornings. It could be that, or it could be something poor fitting or not greased on the brakes. Brake pad honking against the bracket because it fits poorly. Honking on the caliper piston because it can move slightly when all is cold. No lube on the caliper slides or nothing on the back of the pads. Etc.
My daughters car makes an awful scrubby noise when backing out in the mornings and getting on the brakes. Her rotors rust easy and her pads are getting into the rust band on the far edges now too. It's bad enough it will squeal some if she parks in the bottom of a parking garage or something where moisture is high. I'm going to replace it all because it's annoying.
Mine never has made any sound like that. Not even when the front bearings were going. It was tight even when I jacked it up and wiggled. It just sounded like I had mud tires on the front, and the pitch would change just like when going around curves. Especially long ones like a clover off ramp long curve in one direction. Luckily at the time I didn't have mud tires so I knew something was up. I took it in and the mechanic drove it, came back, jacked it up, checked for play, found none, then listened with a stethoscope thing while he spun the wheels. Sad yep wheel bearings. I changed the right side first and 90% or more of the noise was gone. All of it when I changed the left.
Now I have Kelly Safari TSR's and they have some growl to them because I missed the mark on a rotation. My bearings could be bad now and I wouldn't have a clue. Can't hear. Need another set of wheels with street tires lol.
