Michael, can you amplify a bit more on this theory ?
The TR2/3 do indeed have a bit of positive camber (supposedly to move the
contact patch closer to the steering axis and reduce steering effort), and
the bearings are supposed to be quite loose compared to other cars, but I
don't understand what this has to do with either bearing play or the rotor
moving in only one lateral direction relative to the brake caliper/pads.
TIA
