After putting my car on coil overs, I was expecting a little bit more road noise. Although, there is a significant brake dragging sound coming from my right rear brake caliper. I thought it might be the wheel bearing but took off the caliper and was able to spin freely and quietly. I have replaced the rotors and pads making sure everything lines up. Nothing is scraping on the inside including any lines or brake shield. I even made sure the bad of the bad lined up with the notches on the piston. It is hard to believe a brake caliper would go bad on a 2013? Is there something I am missing? There is no noticeable heat difference. Installed a summit adjustable panhard bar too!

 

It sounds to me like you have something wrong other than your brakes. Any dragging will show up as heat. I'd look at the panhard bar.

 

good point, maybe the wheel bearing is bad. I have been running 10 inch rims in the back for a few years now so some extra stress on the bearing might be possible. Do you think the panhard bar is resonating noise because it is halo vs the stock one filled with grain?

 

I only mentioned the panhard bar because that was changed, no real thoughts on why it could be the source.

 

Make sure the hose isnt collapsing also,if it is indeed the brake dragging.
