ok lots of opinions
your vibrating drilled discs will, I suspect, be the same thing - you have hot brakes and sit and lights etc using the footbrake, so the material builds up slightly and causes the vibration, which of course can be measured as run out, for those that thought that proved warping!
The heats required to 'warp' i.e. soften a disc would be huge, and as it is running between two clamping forces that are parallel, then what exactly is going to 'warp' i.e. bend it? if its hot enough to become soft then the disc running through the pads will also keep it straight, and not warped! so the material build up is the real reason, hence part of the cool down lap process after a race (as well as cooling everything else). Sorry if some have spent loads replacing discs, and can't accept it might
not have been necessary, but hey ho!
Anyway the simple fact is that no one can argue with -
I had vibration on several sets of discs on my 156, and used to sit with the footbrake on at lights. the last set vibration occured again, I found this site, did what it suggested, and guess what...
the vibration went! And guess what also?
I stopped ever using the footbrake at standstill and...
the vibration has never come back! I had, did it, fixed it. And no one can argue with that
IT WORKS. Trust me. If you have vibrating brakes, and all else is sound, try this technique, and stop using your footbrake at rest
- what have you to loose???
(well maybe your fillings if the vibration is really bad
