Squeky Breaks
Last thing I want is for my new car to come to a crosswalk and break eardrums.
It's driving me crazy, I don't get it. I've driven numerous cars in the past and have never experienced this problem before.
I'm taking it to the service center today after work to slap them around about the condensation in my headlights and will get them to address the squeaky brake issue as well.
He said something about the brake compound being harder or something where it was produced. So after about a minute or two of me listening I made an appointment with him to take my GLK in today after work to have the brake pads changed out (it sounded like this is a known issue because he did not hesitate to book me in and have a loaner ready for me).
So, hopefully after the service the problem will be gone with my new buttery brake pads

The downside? Probably get a Smart Fortwo as a loaner

Cheers everyone!

Left the car there overnight they will replace the pads for me in the morning and whatnot. Free detailing too

The loaner they gave me was a Toyota Corolla...man...when I got in...I died a little bit inside. lol

I had to run an errand after so I park the Corolla, get back to it and find that I left the lights on cuz it's not automatic. I went to open the door by grabbing the handle and it was locked, and I'm like **** no keyless? I get in and I go to press the ignition button only to find there isn't one. I tried to use the turn signal and ended up batting at air because it's placed so damn high. Not to mention the interior was awful...worst ergonomics ever.
I know, I know, I've been spoiled...but WTB my car back. I miss it already!!
and yes...will be hard to leave the car now...but man...Corolla? you kidding me?
up here around Toronto, dealers won't even take cars other than Benz....they gave it away...well...not if it's a jag or other rare ones...
It sounds like they will be changing my breaks as well. I am sure this is covered under warranty so I won't have to pay anything. Now I have to wait till the damn 17th.
Out of curiosity, those whos brakes are getting replaced, what are you telling your SA and what types of responses are you getting back?
If the brakes make noise when applied, the pad material and the rotor may not be compatible, the pad or rotor is glazed over, or the pad never had a chance to break-in properly.... (you all know that all brakes have a 500-1500 mile break-in period where you're not to use any heavy braking or hard stops when the car is new) What happens is that the pad material doesn't *bite* the rotor properly (because it's glazed, incompatible, etc.) so again it vibrates and/or resonates as it skips on the rotor in high speed causing the pad base to squeal against the caliper piston head.
If they do replace your pads, make sure you insist that the rotors be "turned" as well or resurfaced at least. This is the only way to insure that the pad can properly *seat* with the rotor, but this time make sure you take it easy on the brakes for the first 1k miles or it will happen again, especially if they're using the same OEM pads that came on the car.)
You can do this or you can install Teflon silencing shims behind the pads... these are sold at most part stores.... (do not use the goop found in tubes and cans)... You may wish to look at post #5 in this thread.
The Foreman said that the original brake compound is too hard and causes the squealing at low speeds and replaced them. I've been driving normally and lightly since I took delivery, nothing harsh, no sudden accelerating or stopping, always in C mode. The car has about 1450km on it so far.
The problem started a couple weeks ago so I figured I would get it looked at asap.
The brake pads currently used on the GLK uses sintered steel. The Ceramic pads (as used on other MBs) use sintered copper.

I think they changed the pads to what the other MBs were using as they said the stock ones were made of a compound that was too hard.
Kamen, could you please maybe share the experience, or any documents? so that we can get it printed and shown the dealer if our brakes have the same problem? Will save a lot of time explaining...
