You wouldn't do it or or do you mean you wouldn't be a guinea pig? [img]images/graemlins/wink.gif[/img] - if it works without ruining the disks then it looks pretty good [img]images/graemlins/clap.gif[/img]

For the sake of $25 to try and reclaim a set of disks that are already shoot seems like a gamble worth trying.
If it doesn't work then you have the option to get the disks skimmed up on a lathe anyway.

God point KArl, but the pads dont cover the whole of the disc, well they dont look like they do on my car, so would it cut a groove/channel???

You are correct in that the pad does not completely cover the disk.
As long as the pad used to skim the disk takes out any damage and leaves a sufficant area for the standard pads to bed into then it should be worth a try.

Bushy, did you do this in the end??

My front grooved discs are shagged after a couple of runs warming them up and I think they may need skimming (deffo before donington).

No never tried this

I did have my discs skimmed by AmD but after speaking to Chris, the guy at G Force on the rolling road day he suggested that we never skim them, just chuck them away

If they are truly warped or damaged

I also read a report last year regarding incorrect use of brakes, the basis of this was that people brake hard to a standstill so the heat generatd by braking remains in the pad, which when at a standstill melts/burns a surface of material onto the disc

After long term use you get an uneven build up of used pad on the disc which gives the impression of warped discs

The way to clear this is to warm the brakes up, say 100 - 30 heavy braking half a dozen times but not to a stand still, apparently this will heat up the old surface and redistribute the old material

However I tried this and it didnt work for me
