Scratch on new brake disc

Horizon81

Just had a new set of brake discs fitted and have spotted a deep scratch (can be felt with fingernail) on one disc. Looks like a tool has caused it or it was done during manufacture. Anyone ever seen anything like it before?

where new pads fitted at the same time?, however that looks more like a crack starting

damage in the shop i bet. had it not been,they would have refused/returned it.
Back to the garage with that

New pads and discs fitted at same time. Can't have been caused by the pads I'm sure. If you look carefully you can see a second little scratch on the unswept part of the disc to the left of the big scratch.


If it was caused by the garage, how?

could have been levering a sticky caliper,dropping something on the disk or the likes

Don't worry, it'll be gone in a couple of thousand miles

When you say you've, "Just had a new set of brake discs fitted", when was that and did you have new pads fitted too? That pic looks like a disc that's had a few hundred miles put on it with old pads, and the scratch looks like the fitter levering out the stuck caliper, a while later, to put on the new pads he'd forgotten about.

Post 4 OP says "New pads and discs fitted at same time"

Either way levering out a calliper wouldn't cause a mark like that (unless you're levering it out in some weird way I can't think of). They'd stick a screwdriver or something similar between the calliper and the calliper carrier and lever it up that way. Only pressure would be between the calliper, the calliper carrier and the disc edge. Maybe if they chapped a screwdriver down between the disc and pads to knock the pads out but you'd expect a mark all the way down the disc if that was the case.

Have any of you tried to scratch a brake disk with a screwdriver lol

That is either a manufacturing defect or a crack. Get it changed and keep an eye on the other three.

That's not a scratch, that's a rather large crack or surface defect.

RS2000.

Looks like a grinder has caught it.
