OK, MOT time and been advised (and seen it) that the front disc on the Ully XT is warped. Seen HD prices (Gulp). Anyone got any ideas where I can pick up a new one. :maz: You got any?? or is there a friendly supplier out there that doesn't want to charge me 381 squid?

These any good?

Is it warped or does it 'pulse through the lever'?

Are you absolutely sure that it's physically warped and not that it's just grabbing on old pad deposits? Apparently this is a very common problem.
I understand that it's worth trying to clean the disc and run a harder set of pads that will scour it back to pristine condition.
Others more learned that I will hopefully be along shortly to confirm the specifics of this...

Well if he passed it and the slight pulsing doesn't bother you just carry on riding it ;) It might be worth trying a new mounting kit from EBR before you spend money on a disc ;)

Or clean the mounting kit that you already have...

Have you checked the disc to see if it is stuck fast on the bobbins under each of the fixing point .the disc should deflecf inwards towards the rim when you push aganst it ..do this with each fixing point opposite the calipher.

Will try this one first....... cheers.
OK just checked that - disc is free and moves in when I push it and it is nice and clean.

Instead of saying 'yeah looks ok', I would strip it and clean it, then put it back together safe in the knowledge that you have eliminated it from your enquiries...
