GLE 350de crunch noise when braking
Hi All, I’ve just bought a 2022 gle 350 de hybrid. seems great except one issue, as soon as we drove it away from the dealership post test drive, it started making a crunching/creaking sound when braking, almost feels and sounds like something metal engaging or disengaging, certainly doesn’t sound healthy and you can feel it through the brake pedal. Dealership has taken a quick look and said the brakes look fine which doesn’t inspire any confidence. This happens about half the time I brake and very consistently when slowing from 25 to 15 mph. I have 22 videos of it happening which took me only an hour to put together, I’ve shared with them. I’m still within the return period but would much rather it was fixed so I can keep it. Anyone got any ideas what it could be? See below for a video including sound:

Check you guide rod are properly lubricated and look at your brake pads. do you feel anything in the pedal when you apply the brakes. I had this happen on my wife's E 350 and found the guide rods bone dry. I diassembled the brake to check the pads. They were good and cleaned the lubed guide rods and the brake pad shoes metal pads. Problem was solved.
