Brakes Stutter/Grabbing at Low Speeds
Hi everyone,
I've heard this mentioned by a few people here and there but haven't seen a dedicated thread on it yet so I wanted to post to see how common this problem is and if dealers are doing anything about it or if there was a TSB out there.
What I'm experiencing is a light stutter or repeated grabbing of the brakes when pressure is applied to the brake pedal at low speeds. It's a rapid sensation when coming to a stop from a low speed, for example at a light or in traffic. I'm wondering if it has to do with the brake drying function.
One of the unexpected surprises I've been hearing about (only after buying the car of course) was that these cars eat brake pads. Given it's $1,100 for 4 pads, I'd obviously love to know if anyone's dealer has resolved this for them.
Thank you in advance!

Definitely not normal in any car that I've ever driven. I apologize if I'm not doing a good job explaining the sensation. I was hoping it might be relatively common so I could find a solution.

With your iron rotors, have you or a detailer used an Iron-X type product on the wheels, callipers and rotors.
If yes I have found the size of calliper means only 2/3 of the rotor has ferrous iron stripped from it by the cleaner with 1/3rd retaining its surface layer.. the alternate surface condition can cause a brake pulse ... even with extenaisve brkaing this didn't deminish until I figured to clean the rotor again, moving the vehicle forward a small degree and completing the rotor..... this solved this issue for me..
i informed the mercedes Techs as they were pusrsueing warped rotors etc but i was sure it wasn't as actual warping is very rare...
Hope thats helps?
