Story so far - Upgraded to UK Spec brakes from Mr T ~5000miles ago. Spot on. Brakes have never been used in ernest during that time.
About 2 months ago started getting a vibration at front very like warped disks - took wheels and disks off, rudimentary tests showed no sign of warping in either disk. Bit of play in offside bearing and weeping seal at balljoint but no play in ball joint, cleaned mating faces, put them back together. No improvent.
Bit the bullet and purchased upper arm and offside wheel bearing and flange, fitted them - no improvement.
Bit bullet again and bought nearside bearing and replaced it just now - no improvement
So I am back to the warped brake disk theory although as I said, nearly new, look new (ie no sign of being heated), and radimentary tests with a straight edge show no sign of warping.
Should I buy one disk (knowing the way my freakin luck is at the mo, it will be the wrong one) and try it on each side to establish if I do indeed have a warped disk?
Has anyone warped a brand new meaty disk without knowing about it, I don't drive vigourously the whole time and find it hard to believe that I would not have been aware of it had I braked to that extent? Would I have any come back on Mr T after this time if a disk has warped through manufacturing defect if that is the cause?
Any advice welcome on how to establish the cause before spending more money on disks would be welcome?
