In an earlier contribution to this discussion,\n[QUOTE="EBG"]\nHow important is it to replace the rotors on a 98 s70 after 60-70k?\n(I've been told it's imperative).\n\nI can appreciate perfection but if it can wait, so be it.\n\nThe braking is smooth...there is some wear in the rotors but as long\nas they do the job, I don't care what they look like.\n\nAlso, typically how often should a midwest car (my S70)\nneed more AC refrigerant? If I'm getting a certain temperature out\nof the vents....I'm ok?\n\nWhat temperature should it typically read?\n\nThanks for any help.[/QUOTE]\n\nThe brake discs need to be replaced if they are worn to below the minimum\npermissible thickness, are badly scored, or run out by more than the\npermitted amount. Otherwise keep them. I certainly wouldn't replace\nperfectly good discs just because they have done a certain mileage.\n\nDon't know about the second question.
