Thanks for the info. I did the new pads myself and used MB pads from the dealer. When the brakes first started grinding the old pads were only 50% worn, although the rotor was hashed. The old pads were MB from the dealer. Are all of MB pads organic, or should I ask specifically for them ? I have always used MB parts for brakes because of the "not stopping problem". Are aftermarket parts equitable and safe ?
