Yes, his has a carrier but the principal is the same.

There are some significant differences. What are you going to lever against? You're a brave man!

I'm going to use an adjustable spanner on the disc

So, in effect, you're levering against the turrets?

Apologies in advance for sounding rude.

These are your brakes!!! Subject to thermal cycles and high load. The professionals can't straighten them, but a bloke on the web says you can do it with a magic marker and a crowbar?

I would think again. It may be a case of sucking it up and forking out.

I would also call your dealer and see if they will give you a discounted price, given the known problems with discs on this model. You never know?

Your discs are the same fitted to

one of which in the list is the F800S

Searching for F800S disks on ebay brings up

and for the F800ST

Sherlocks have some used ones that they guarantee are straight. One for 39 and the other 49 quid

Hi,
PITA to buy a new Disc or Discs I know but these are your brakes we are talking about!! Trying to straighten with an adjustable and brute force My 12s was given an advisory for a warped rear disc last MOT but I wont be trying to force it back into true. End of the day they are your brakes but I might just have to share the road with you.

Peter.

Hi,

Thanks, they aren't the same mine are the later type that have the fixed washers.

I'll be gently bending metal back a few thousanths of an inch. I'd imagine that the same metal is exposed to much greater forces during braking.

I'll let you know if it works or not.

It can be done.

I'm guessing they'll skim them maybe, which has been available on cars for years.

If it were me I'd just get new ones give a new pair of Brembos are £198 and, to me, there's two things that you don't mess with on a big bike. The tyres and the brakes with suspension nibbling at the definition too

Motoliner said they press them flat.

S T said he spins them in a jig and bends them back.

Where can I get a pair for £198 because I've been quoted that for one.

Ebay have brembos for 98 each

However, even cheaper if you don't mind the wavy ones are these
http://www.ebay.co.uk/itm/One-Front-Arm ... 43bbbd4563

at £69 each and they have 10 in stock .... and it says 06 to 11 for the year so should be a fit

Hi,

Thanks appreciate that will probably get some if I can't sort it out myself.

I'll have to check the run out to ensure the disc is the problem and not the wheel, I'll see how far its out, I can't see a little "tweak" here an there can hurt!
