Hi, in My 2008 Mercedes Benz ML350 4 MATIC brake is very low. We have changed, new brakes, Rotors, Booster, Master Cylinder, Tested Check Valve and still same issue. What could be the issue ?. Bled brakes for any air several times as well. There is no leak in Brake Fluid anywhere. Fluid is replaced new.


My car has 145000 miles. My car has an automatic transmission.

Here is my VIN: 4JGBB86E68A308649

What you said make sense. By any chance do you have part number required ?. I will hookup my MB DAS Xentry and see if that gives me any code or error. I did not know that DAS will give me this info but will try.
