There's some bits that are questionable, but apart from that, it makes quite a lot of sense.

good article, think mf and a few of us lesser mortals have been saying it for years - remember around 07 when every other thread was about warped discs?

Its a fault on the M5 too and everyone worries their discs are warped. I am 99% (uneducated but) certain its due to the control arm bushes drifting/flexing too much c pausing vibrations in braking leading to deposits, hot spots or whatever. Mine ended up so bad that I felt the car was about to shake apart so I replaced the bushes with polly and had the discs hub surfaced and 18 months on no problem.... the problem occurs under standard not race conditions so I am confident its sorted. The problem certainly started to appear more on road cars when we ended up with bushes to isolate road/suspension noises

I'd say it has been posted on the forum several times over the years.

And you could still argue whether AP problem of bumpy brakes is down to "pad deposits" or just plain bumpy discs.
