    The issue of brake rotor warping because of overtightening with an air
    wrench (rattle guns down under) was also a BMW problem.
    A local brake pad supplier has developed a formulation for European cars for
    the hot, arduous Australian conditions and in trials got more rejections
    from BMW than expected.
    They tracked this back to mechanics using the power tools instead of torque
    wrenches as recommended.
    It could be the same with Pugs.
    However, when I raised this with my mechanic, he refused to believe it and
    said it shouldn't distort because it's metal against metal. His offsider
    agreed.
    Torque tightening of the wheels was essential with the 203s, 403s and 404s
    to avoid warping brake drums.
    Incidentally, the rotors on modern Pugs are much lighter than they used to
    be and wear much sooner. I have seen 306 rotors substantially dished at
    30,000 km. But they will take only one refacing and then have to be
    replaced.
    It is part of the European philosophy to reduce the weight of cars. Rotors
