Why are my discs squeaky?

Evening all,

On my 2010 Carrera Fury i've got Juicy 3 discs which have started to squeal and squeak and a certain point during the revolution of the disc. If the disc gets wet it no longer does it a for a short while and then start again.... it is seriously cheesing me off making my trusty steed look a £10 boneshaker.... the disc is warped as far as i'm aware but this is driving me mad.

Has anyone had this before and know how to cure it?

Lastly what is the best grease to lube up the axle on my Suntour Epicon fork?

Cheers

    if it is on an off. straighten the disc. see how in the teck links sticky above.

    then what are the pads like?
    what is it rubbing on? worn pad or wearing the caliper?

    what axle is it?

    You can gently tease the rotor straight with a clean adjustable spanner, or a rotor truing fork as this......

    It's a case of spin wheel find the point of contact gently bend rotor away from contact then spin again until the squeak stops!!!

    Or worst case replace the rotor with a new one...

    As for fork grease i love the stendec stuff works a treat on air sprung forks...

    Now the thing is this..... if it not on the bike riding it... it doesn't do it! possible flex in he frame and such?

    The front axle is the axle that comes with my Epicon fork Qloc... the rear is a standard screw quick release. I think.

    Thanks
