Emergency brake adjustment for 2009 ML350
Hi,
My Emergency brake does not seem to hold the car when i am on a slope even when i fully stepped on it.
It has gotten worse thru the years, and now it just looks like it is not holding it at all.
I have read that there is a nut in the rear rotor area where you can tighten it, but that was for a 2003 and not 2009.
If anyone have knowledge on how to adjust this for a 2009 model, please let me know.
Another question, is Parking brake same as Emergency brake? Different people seems to be referring to it differently.
Thanks.

Yes the Parking and Emergency Brake are the same.
I have not looked into adjusting them. When was the last time your car was in for brake service? I would have expected the Parking Brake to have been adjusted.

I have a 2008 ML and have adjusted the park brakes on this. (I'm used to calling it the hand brake by the way!).
On the rear wheels you have your brake discs (for the hydraulic disc brakes) and in the centre of these brake discs you have a brake drum on the inside of which reside the brake shoes for the hand brake. There is a hole (about 10mm in diameter) in the brake drum through which you can turn a wheel on the inside using a flat screw driver to adjust the brake shoes up or down.
The best is to first take off the hydraulic brake calipers, ensure the hand brake is fully released and to then remove the brake drums so you can familiarise yourself with the brake shoe layout and adjustment wheel rotation on the inside. You can then either adjust the brakes up with the brake drum removed but always ensuring that the brake drums will still slide back over the newly adjusted brake shoes, or you can first put the brake drums back on and adjust the brakes up through the hole in the brake drum with a flat screw driver. Ensure that after the adjustment is made, the brake drums still rotate freely when the hand brake is in the released position.
