From day, one and continuing through my 1000 mile break in period, I have experienced an annoying brake squeal when coming to an stop under light braking. On other vehicles I have used Disc Brake Quiet spray on the back of the brake pads and have scored the brake pads and rotors, but I am hoping the dealer can correct this problem. Has anyone else out there experience this? Thank you in advance.

 

Try bedding-in the brakes.

 

Yes thank you for the reminder. I will do so.

 

You're welcome, hopefully that solves or very least mitigate the issue.

 

My 2021 GLB35 has it also. Now it sounds less as the brakes got older. I found below MB Technical Service Bulletin for squeaky brakes on GLA35/GLB35:

I gave it to MB dealer during 3rd year service. They said I may need to change the brakes soon, but still they are fine at 25K miles...

 

Yep. I did the standard procedure of repeated slow down to 5 mph from 35 mph, 50 mph, and 75 mph and then cruised to let the brakes cool. Initial results and my expectations are that this will solve the squeal problem. Thanks again for the reminder. I've done this many times on race cars, but forgot about it until you reminded me.

 

Excellent! I will keep this in my back pocket if the bedding procedure doesn't provide a permanent solution. Thank you.

 

Sounds good, happy to hear it worked : ) Enjoy the vehicle : )

 

I know it's "brake" not "break." Like for others, I assume my spell checker must have changed what I typed. Who in these days talks about brakes when one is only worried about when their next break is?

 

Don't worry, happens.
