Brakes are now squealing, is it normal?

My car is 1300 KMs now, brakes start squealing the last few feet while coming to a stop. They don't make any noise at other speed, though. Is it normal? I checked the rotors, they look fine.

Thank you!

try wiping down your rotor and cleaning around the pad a little bit. I had a mild issue of annoying squealing the last few feet of coming to a stop but it quickly disappeared when I cleaned it. Might not work, but it's a suggestion ^^

Had you just washed the car or got the rotors wet? After I wash the car, the next day the brakes squeal a bit until the light rust gets rubbed off the rotors.

Brake squeal can be cause by accumulated brake dust. When you wash the car, run water through the calipers and then drive it a few blocks to dry them out, thus avoiding that overnight rust spot behind the pads.

Bring you car up to highway speeds or above on a clear grid or back road, MAKE SURE NO ONE IS BEHIND YOU! then firm but smoothly press the brake engaging the abs. repeat 4 or 5 times and presto! no more noise.

Pads replaced free

Hi IMBANE: read on a M.Benz forum a post by a U.S. C-class owner(can't recall what yr his unit was) , their "A" service was at 12,000mi. He also had low speed brake squeal, along with ( as a lot of German cars) brake dust problem. When in for his A service at 13,000 mi, he complained to the service mng about it, was told, if he had brought it in before 12,000 miles there was a 'service bulletin' out on the problem... talk about steamed!
I also had this concern, when rolling to a low speed stop, the front brakes squealed. I hung my cellphone out the window pointing down at the front wheel & videoed it and made an appointment for my "A" service even though I had only 15000 km on the car ( "A" service schedule is at 20k, 2009 C class)
They replaced the front pads with an upgraded pad, no more squeal and dust reduced significantly. ( still have dust on the rears but not pushing it).
Might be worth a try , make a complaint before your first service rolls around. Good Luck.

Thank you! I didn't call my dealership since I still expected to see it disappear some day... I'll call them if it's getting worse.
