i noticed that my brake pedal was hard to use, little travel( i run no booster, so i am use to the pedal feel) but this was diff.. i thought my fronts were draging,, so i pulled into a mbz shop, use the hose to cool down the front rotors.. hum.. they were ok, but the rear. as soon as the water hit them, lots of steam... i know it is not the rear hose, because, i did not set the handbrake, and as soon as the rear calipers cooled down with the water she drifted forward... so i drove it home.. agian rear wheel drag.. water on the calipers ( no handbrake) an as soonas the water cooled the rear calipers down, she drifter forward... i take really good care of my car, i change the brake fuild once a year, last change... 8 months ago. i am thinking about in the morning, jack up the rear, remove the calipers, take them aprt, and see if anything is wrong, any ideas here?
