Argh one of my discs is warped.

The garage repaired my bike after my off and returned it to me but last week a noticed an issue with the rviets on my disc. They picked it up again today and turns out my disc is warped. So it would seem that they didn't spot this issue first time round. I rode the bike for about 1'000 miles but then the disc problem occured last week. I am 100% sure that this problem has come about from the initial accident as it's the same side that I hit the car on. Thing is the garage are now saying that they will not replace the discs as I have ridden a considerable distance and anythnig could have happened to the bike in that time. They said they have straightened the disc and flattened the rivets so that it all now lines up but is this safe? Why did they carry out this work if they thought they we're not responisble anyway? A guy at work seems to think I should replace the discs.

Help, advice please.

Take it to a bike MOT place to see if it would pass the brake test (should be free)
I don't think they would so something unsafe so if it's now straight I would be happy IMO.

I would be wary of a "straightened" disk, it is such an important item that no risk is acceptable IMO.

Whereas I can't imagine how it could go wrong. A disc is either straight or warped. If it's straight now (as proved by the MOT tester) is it more or less likely to warp in the future? Just because it has been straightened I can't imagine it's anymore likely to disintegrate to dust in the middle of using it, or there wouldn't be an industry of straightening metal (by Motoliner etc.)
Obviously it would be best to get a brand new disc as a result of the accident, but if that approach has been tried and failed, I personally wouldn't be putting my hand in my pocket to buy a brand new disc, and who's to say a second hand disc off ebay would be any better than what you've got?

Well it is straight and seems to works fine. Insurance company won't replace the discs so I think I will do this myself. Going to get some nice wavy ones made up from all bike engineering, about £100 per disc and £50 for the rear disc. To be honest as I've done 22'000 on the bike now the discs could do with replacing soon anyway. I'm just a bit miffed that the repair shop (Altamura in Camberely) missed this and are blaming me. Twits. Shame really as everything else they did was perfect.

Fair enough, if you're getting something better for your money. yeah shame.
Should still be worth trying to get the garage or insurance company to make a contribution then, especially if you are going to end up with a receipt proving you had them replaced.

I guess before they put there hand in their pocket I would have to prove that the repair job is unsafe. Only one way to find out but I'd rather not crash the bike again!

I've had a few warped discs (mainly Kawasaki ZZR1100 ones) straightened by Hagons in Essex, at 30 quid a pop it's a damn sight cheaper than buying new ones at however much they cost and they've never shown any sign of being repaired or being unsafe afterwards.
