Thanks but I'm after Galfers.

Dont go thinking they are not worth repairing.It only takes a few thousands of an inch to make the lever pulse.If your handy and can get the disc off the carrier(assuming they are floating), they can be surface ground.

I have ground the front disc on my own honda spada at work, using a lathe and the tool post grinder. Worked ok too.

I would definitely buy the ones off bits for bikes if they were correct. Unfortunately I did some further research on their site and those are the same code as the rear disk for other bikes that share the same brakes (CB600 Hornet for example) so I think they have just screwed up. The cheapest I found any new non-Chinese disks for my bike is $600 so that is what makes me think other options might be worth it.

Send them an email,
they will sort you out pretty quick, when you sign up to their site they also email you a $25 off voucher.

I emailed them, $400 each, ouch!

I've seen (someone actually doing it) a disc de-lipped with an angle grinder

Heres some pics of the first set. You can see the differing wear patterns on opposing edges of the disc.

Cheers for that, hadn't considered that they would get something as simple as that wrong, I'll check for it in the future.

I think I'm going to try F1 engineering in Hamilton. COuld be just the carrier, I can't actually see where is bent, just feel the pulsing in low speed front braking.

It could be that it's not warped but unevenly worn around the disk ie. the thickness of the disc might vary. On my bandit it was by 0.025mm on one disc only and I could feel the bike pulsing slightly when coming to a stop under light braking. I got new discs, then noticed the (within spec) side to side run out was making them brush the brake pads at the high point and that they were starting to wear more at this point on the disc. So I switched back to the old discs and tried replacing the piston seals in the callipers to see if it'd make the pads retract further. It didn't, but I found the pulsing wasn't so bad anymore (disappeared even) and I just ended up using them till they got below the minimum thickness, then put the new discs back on.
I'm not sure if cleaning and rebuilding the callipers (with rubber grease) reduced the pulsing or if I put the old discs on at a different angle (although if the pulsing was due to the variation in disc thickness this shouldn't have affected it), or if it was the new brake pads or what.
I've just bought a gsr600 and the brakes are doing the same thing, will have to measure them and test them and decide what (if anything) to do. I'm hoping it might just need the callipers cleaned and reassembled.

sorry mate, I don't want to jack your thread, but I'm looking for anyone else that has had worn rivets on Brembo disks - which allows the outer part of the floating front disk to move (a lot)
