Coachgeo,

Power Windows and Sliding Roof and not affected by vacuum, they are all electrically operated.

If you have a dial indicator, you can check the warpage of the brake rotors by putting the indicator against the rotor and turning the rotor. However, I don't know what a passing measurement would be. If you find that one has a lot of warpage, you should replace it and the one on the opposite side. You might only need front or rear ones, not all four.
