2017 C300 AMG sport line. Car has 57,000 miles. Service it regularly. Had my brakes and rotors replaced back in November at a shop I am confident does good work. Recently I’ve been hearing an odd ticking that i initially thought was probably a loose brake pad. I took it back to my shop and the shop believed the cause to be a loose brake shim. The shop replaced/reset the shims but after a few days I started hearing the noise again which makes me wonder if this has something to do with the caliper.

I took a video of the noise and wanted to know if anyone had any thoughts.

Turn up the music. Problem solved.
