I have a 2002 c230K. I have adjusted the nut for the parking brake (located under the rear seat) all the way as far as it can be tensioned, but it's still not enough to keep the car from rolling, even after bottoming the pedal.

Can any other adjustments be made?

Thank you guys.

 

Yes, you should start by backing the nut off that you just tightened. Then remove the rear wheels, and looking through the lug bolt holes turn the rotor until you find the adjusting wheel. Sometimes called the star wheel, adjust the star wheel until you can no longer turn the rotor, then back it back off 4 to 7 clicks or until you feel a slight drag on the rotor while spinning it.

 

Thank you. It worked just fine, the star was stock a bit after some lubricant it finally gave.
