Need a little help. I recently got the tech specs to change my back rotors and brakes on the merc. website. I located the Auto Tension Adjustor and it seems you just need to turn it clockwise before removing your rotors and do the reverse once installed. I talked to an individual who did this incorrectly and had his rotors pop off while he was driving down the road. I do not know who much stock to put in this being he said he did not test the e brake nor the regular brakes before he drove off. Is this possible and does anyone have any tips when doing this. I am hoping you G wagon guys might be able to provide some 411.
