Screeching Brakes on the GLC
I wanted to start a post to track this issue. If someone has this resolved, please let me know.
Does anyone else have this issue of screeching brakes when pulling out of the garage or driveway? The issue comes and goes depending on the day. Usually when the weather is cooler. The sound is loud and annoying for a new car.
Is there a fix for this issue?
I brought my GLC into my service center and gave them the bulletins as posted in this forum:
https://mbworld.org/forums/c-class-w...ng-brakes.html
LI 42.10-P-060688 - Install special order shims for front brakes to eliminate cold weather squeal to adjust the angle of the pad
and this bulletin LI#: LI42.10-P-063311
I was told that those are for the C300 and doesn't apply to for the GLC. No solution for the GLC as of now.

If my service center calls with a solution I'll let everyone know as well.

Doc, I wonder how the timing of the build of your car compares with those having the issue? Sometimes they "fix" things in production when issues are identified so if there's a recall or service bulletin, they have less to fix and they aren't perpetuating the issue with every build. Companies are usually very slow to publicly acknowledge and address issues. Given the time it takes me to run things through corporate legal for approval, I know why. And my stuff is generally way less important/visible than this stuff.

My car was built last week of January. Will ask one of my fellows if his wife is having any issues with her car. If she is I will find out the build date and post. They bought their GLC before I got mine. They bought one that was in stock.

That said, its not unusual for disc brakes to squeal, especially when cold. This problem is exacerbated when the brake pads are hard.
To cure the problem I employed a process known as bedding. This involves making several maximum effort stops from about 80 mph. The objective is to get the brake pads hot, very hot. So hot you can smell them.
As expected it cured my squeal.

That has not worked for our brake squealing. Never have experienced squealing so loud in any car we have owned. Plus, this does not just happen when it is cold out. I think it is the same issue that some of the C class owners have, but Mercedes has just not acknowledged it yet.
I had the same problem. Backing down the driveway in the morning and listening to brake squeal.

I just installed new pads and rotors on my E320 and the same thing was happening to me. I heard taking the pads out and taking 100 grit sand paper and sanding the edge of the pads all the way around will stop the squeal. I tried this and then took the car out and hard braked it several times from about 50 miles per hour.
Only after a few times it started to work. The squealing was worse when you were backing up and putting the brakes on lightly, but finally the noise has gone away. Hope this helps.

Mine has a build date of 11/15. Had very minor brake squeal on backing only until (it seemed) the rotor metallic coating had completely worn off during the bed-in period. No squeal now. Others say this was pure coincidence. But, of course, with DBV's 3,300 miles and continuing brake squeal, something else (?) is happening.

Hello Mikey, Very funny. 
Actually finding big pavement was a problem. My mechanic showed me a two mile stretch of very lightly travelled rural road, perfectly straight, with no driveways or intersections and sight lines from one end to the other.
Fortunately, this illegal activity is only done about once a year when my mechanic beds the track pads on my Vette.

We took our GLC to the dealer today to check out the squeaking brakes. They knew right away of the issue and also said Mercedes is well aware of it and working on an official fix. It sounds like the parts they will need use (brakes, etc..) are on back order for potentially a couple months.
I am just glad Mercedes knows it is a problem and is going to get it right.
Kind of funny, backing out of the MB dealer and our GLC made the very loud squeaking sound and everyone outside turned and looked.

No - It is when you go in reverse and it is a extremely loud squeeking/squealing noise. It has continued to occur even in the warmer weather.
Can not wait until Mercedes has an official fix.

Hi DBV, any update on your reverse squeeking issue? Did your dealership come back to you with an official "issue number" (forget what it call) referring to this problem? Our Glc have just reaching 2000kms and start having the same issue. Took to the dealer but they have no idea...
Thx!

Got back today with an advisory fix.
Some good news for us waiting for a solution.
based on LI 42.10-P-063978
They replaced both front disk brake pads and lubed the contact point of pins and brakes. I hope that is the end of the screeching noise in the morning

Thanks nycrounders!
Any chance you can get hold of a copy of the TSB from your dealer like one below?

My dealer in Australia try to help but they can't find the details base on this TSB number.
Many thanks!
