I went thru this on mine a few yrs. ago. Replaced several sets of rotors for runout issues and several sets of pads for squealing issues. Did the paste thing as I've always done with other cars.

In the end, the solution was to buy a set of MB dealer pads. I realize they may be made by Jurid, Pagid, etc. on any given day, but that's what did it for me.

I will never use anything else.

My 2 cents
