Chirping Sound Over Bumps

I have a 2014 C300 and I am having an issue with the brake pads. Our pads have the metal pins on the backside of them. The first time I had this noise I took the car in to the dealer for them to track it down (CPO car). They tracked it down to these pad pins, and the issue was solved for months.

The fix was to scrub them and grease them. The issue seems to come back every few months. Does anyone else have this issue/a long term solution?

When did this issue start ? I have the same year same model... but haven't heard such chirping sound yet

How many miles on your vehicle..

How frequently have you changed your brake pads and rotors ? Do you use OEM parts or 3rd party parts.

Thanks in advance.

Started around 30k, all OEM parts changed on MB schedules, and I'm at 43k now.

Apparently its somewhat common.

I mean I can try, but you'll never hear it on an iphone video over my muffler and resonator deletes.

I would try a spot of oil on contact points regularly.

You can inspect other components of your undersides at the same time.

If you don't have facilities drive it over a spoon drain or similar to gain access.
