Brake disc skimming
Discussion

I would get them off and make sure they're mounted accurately before assuming that they're warped. Warping isn't as common as is often thought and if they're new, it's more likely to be mounting or some other issue.
Skimming them on car will solve the issue of course. Soham, Cambs. too far? Disc skimmers.com has a good reputation.
Ok thanks.They're not new discs, but the mounting is fine. New wheel bearings have also just been fitted.Skimming them on car will solve the issue of course. Soham, Cambs. too far? Disc skimmers.com has a good reputation.

I saw that place in Soham, but it's a bit far for me really, i'm in Rugby. There's a place in Northampton that will hopefully be able to do them, although they're concerned about ground clearance of the car.

More likely pad transfer material, not warped discs.

I meant to say in my previous post that they're NOT new discs.

Whether you believe that article, or not, the route cause of 'warped' discs comes from them being fitted with excessive run-out.
The mechanism is that the pads are in contact with one section of the disc longer than the other and this leads to uneven wear (to the thickness). If the run-out exceeds the normal 'knock back' of pads, then this may happen very rapidly. Even when you correct the run-out, the uneven wear is still present. They may, over time, even up but sometimes the easiest option is to replace them.
It's VITAL that the disc and hub mating surfaces are spotlessly clean when assembled and that bearings are in good order.

The bearings are brand new.

OK there's a clue. Any run-out on the car they where fitted to will have transfered to the disc. Stick with them, they may sort themselves out. (as a side note it's always a good idea to keep discs in the same orientation to the hub)Gassing Station | Caterham | Top of Page | What's New | My Stuff
