I’ve finally got around to measuring my hubs and discs. Cleaned them up, so there was no mistake in the measurements. The run out on one hub was 0.03mm and the other 0.02mm. (The later being the new hub just fitted.) The run out on the discs, when fitted to the hubs, were 0.06mm for one side and 0.08mm on the other. (Therefore within tolerance according to my manual. Disc run out should be less than 0.1mm) These are Tarox discs, and are only on their second set of pads, so are fairly new. I rotated the discs 180 degrees on the studs, and then took it out for another test drive, and no difference. I did a hard brake from about 110mph to stand still, and the car tracked true, and no pulsating on the brake pedal. So the discs are not the problem.

When the gauge was on the hub I tried to move the hub up and down to check for play, and there was no movement on the gauge.

I’m now convinced that the shocks are the problem, as the problem only arose after they were fitted. I’m going to buy some second hand shocks, and try them out to see if the Konis are the problem.

Will post my findings when done.

Cheers
John
