Ever since I bought my BT7 there has been a small squeak in the right front
wheel at speed. I check the pads and installed new bearings, checked the
pistons and everything else I could think of. The squeak would disappear if
I jacked up the front end and spun the wheel by hand so it was very
difficult to hear where it was coming from. Finally I put a machinist's
gauge on the rotor and found it to be 15 thou out. Is this enough to cause
the squeak? If so, can the rotor be trued in a lath or must it be replaced?
What are the tolerances on the rotor being out of flat and perpendicular to
the hub? Thanks for any advice. Cheers, JL
