Brake disc skimming

[dave993cars]

Hi all

Anyone know of a garage or engineering company in Scotland who will carry out brake skimming on 993 C4S disc's, the car has been sat a while plenty of meat left on them but need a tidy up, thanks.

I would speak to your local OPC they could probably help? Some of them down here in the South have the equipment, and I dare say if you wanted to take off the rotors yourself most engineering firms would do it for you.

I know that OPCs don't do skimming, there view is replace. Any decent firm with a lathe should be able to do it. Better if you can find someone that skims on the car if you can.

Had mine done on the car, if you do, make sure they clear out all the cross drillings afterwards, can be a right pain!!

If the cars just got surface rust on them , just give it a blast up the road that will clean them up , if its really bad and pitted then new ones are needed

All main dealers should have a ProCut on the car disk lathe even though they will say they have not, they have to have one for warranty repairs to disks which have picked up pad material as Porsche will only authorise the disks being skimmed, not replaced.

If you call ProCut, they will let you know where your nearest garage with the kit are, we have one here, possibly the least used machine in the workshop, as not many people will pay the labour rate for it to be used, as a big cross drilled disk has to be done one side at a time and with setup might take up to an hour per disk.

Thanks all for your replies, I thought the on car machines were limited to the size of rotor and couldn't take the 320mm discs from the C4s/Turbo, I am sure I read somewhere that you had to remove some part of the lathe to accommodate these discs, I may be wrong but it may be another manufacturer of on car skimming machines, other than ProCut, certainly the local OPC say they don't do disc skimming.

About 3 years ago ProCut had a whole load of their standard on the car brake lathes for sale because they replaced all the ones at OPC's to a new version which could deal with the bigger disks.

In particular the bigger disks they were talking about were for the Cayenne Turbo 350mm brake disks.

We have had our current one since 2007 which was the same one as the OPC's had which does the C4S and Turbo without a problem and without having to remove anything. But I do recall when I bought ours with the proper Porsche hub adapter that there was a smaller version of the machine which needed something re-jigging everytime you needed to do a bigger disk.

I didnt upgrade at the same time as the OPC network had to upgrade theirs because the only cars we tend to use it on is for winterised cars in the springtime as part of recomissioning for customers, and for track cars which had a pad material transfer issue after holding the brakes on in the pits with hot disks which causes brake shudder (same customers do this time and time again lol)

They might not want to admit they have one because it stops them selling new disks, but unless the network has told everyone to hand them back to ProCut and stop giving them space (theirs are leased) and I am unaware of that happening, they should all have one.
