Brake disc skimming

nxbyveromdwjpg

Think I have a warped disc, someone mentioned having them skimmed might be a cheap solution rather than forking out for brand new discs....

opinions? great idea or waste of money....??

I thought this technique made the brakes less effective as they are thinner and therefore more liable to break, especially as warped break disks are only a problem really under hard breaking, Im no expert but I wouldnt want to risk my life on saving a few yoyos.

From what i understand, they scrub almost a millimeter off the disc, and then resurface it to replace the lost material. I got a disc resurfaced at 42k miles and am now at 61k miles with no adverse effects.


edit: the reason i got them resurfaced was that the brakes started making a horrendous rhythmic squeaking that increased in frequency with car speed, whether the pedal was pressed or not. We were pretty concerned about permanent damage, so we got it towed to a garage. They said the rotor was warped, which makes sense, they resurfaced both discs and replaced the pads, which i knew were due anyway. it was like $150 for that and a drum clean & adjust (about the usefulness of which, i'm not too sure). I'd recommend it, but ask for opinions from various garages, ask what it entails, get lots of quotes, and watch them in action when you commit to one place.

If the garage is competent and "grind" them rather than "turn" them, you can get a better finish with less removed, but it would be more expensive.
"turning" has to remove a larger depth to remove anything at all, and in many cases is done by some tht is not a professional turner eithr, so they tend to be turned out of true (like warped).
Thinned disks will tend to re-warp as already described.

I have used aftermarket replacements to great effect. Cost the same as turning, but better.

discs are cheap, dont mess about. brembo wnsures disc runout at less than .01mm.

What car are you driving? What mileage is on the discs? Who diagnosed the warped discs - what are the symptoms?

:eek: Geez with something as safety critical as brakes, I would not risk having the skimmed or whatever. I would be straight down to my local garage to have them replaced, no matter what the cost
