Front discs - 1 warped, 1 not. Looking for advice opinions, help, sarcasm etc.

(Second attempt to post... aim was a bit off first time!)



There needn't be a caliper fault, though an overhaul is a good idea anyway. A bent disc can be caused by incompetent drivers giving the bike a nudge when parking… if they get the angle right they can easily apply enough force to bend the right disc without knocking the bike over if it's on the sidestand.
Whatever, it certainly sounds like you need a replacement. I get about 40k from them and have bought second-hand ones on ebay several times without a problem, though bought new EBC discs about 18 months ago.
If your bike is still on the originals then the bolts will be a bit stiff. I prop the wheel up over a low flame on the stove for twenty minutes until the alloy is getting uncomfortable to touch, then they can be undone without any drama because the heat softens the thread lock and expands the screw holes due to the different coefficients of expansion of steel and aluminium.

[size=1em]Bit random, and as likely as being bent by a pram or shopping trolley!!![/size]

[size=1em]And at the moment there is no real evidence to suggest a new disc is needed at all yet, not until he's done a few tests anyway?[/size]

[size=1em]This is what i was saying earlier about people immediately jumping to the conclusion of a warped disc, even though it may not be the case! [/size]
[size=1em]If they were a cheap replacement, then fair enough, but they're not, so it's worth finding out for sure before splashing cash about for fun.[/size]
