Brembo 320mm cast iron full floating discs, new & unused

Pair of Brembo 320mm cast iron full floating discs; two discs, new and unused, OE for Sport Production versions of 851, 888, 748 & 916, also Superlight Mk I, III, IV & V and Monster S (1997), will also fit 851& 888 Strada, 748 Biposto, 916 Biposto, 900SS, 750ss, 600ss, early Monsters (to 1997, may fit later Monsters), some Bimota's of same era.
This was a second set of two sets I bought for my two 888's but have decided to sell one of the bikes hence one set for sale. Took a lot of tracking down after having bought 2 used pairs that were frankly worn out - they have transformed the brakes on the 888 I am keeping - way more stopping power with lots more feel/progression and much much less force required at the lever. Why buy non OE discs for your classic SP or SL? Or greatly improve the brakes of your non SP bike - don't take the risk of buying used iron discs, strict wear limits! The galvanised finish protects the disc from rust and quickly disappears with use - no coating to wash off. Price £750 includes postage

Pffff expensive hobby......

sod that. Not when a decent set of brembo serie oro or supersport discs will set you back half of that.

bless you Sev, of course you can buy generic discs for less money but whilst they may be decent they are not comparable - the low cost discs stop the bike but take a lot more lever effort and give way less feel, I now have a set of these cast iron discs on my 888 and I can honestly say they have transformed its brakes - I had previously looked at buying a Brembo 19 RCS radial master cylinder to make braking better on the standard 320mm steel discs but with tse iron rotors I can now stop with 1 finger and have so much more feel. Oh, and everyone knows that these are the real deal and they look choss, in the day they were fitted OE only to top shelf bikes - Ducati Sport Production, Bimota, Guzzi Daytona RS, if you need new discs you'd be mad not to consider these if you can find the extra cash, you'd likely get most of your money back should you decide to sell the bike and replace with the standard discs. Why not enjoy the best?

Thank you for this truly educating post.
I don't think that i've ever owned such lauded braking hardware, so I'll look to furnish my own machinery with such.
I just need to check what I've got on the old snotter at the moment to compare.

So would you say that in your opinion the cast iron discs are far superior to the steel rotors that brembo sell now, over and above the likes of the SBK and supersport rotors that one finds on all their race equipped machinery?

Also, what pad compounds do you use?, as I understood it, since the removal of asbestos in friction material manufacture they found that the non asbestos friction surfaces induced to much heat into a cast iron rotor and sometimes caused it to catastrophically shatter under racing (god level talent) conditions.

I've such limited experience in this field that it's always handy to hear it first hand from someone who knows. (y)

This is not my opinion, it's what Mode Performance (Brembo UK importer) told me: from a retardation performance perspective the iron rotors are far far superior to the 'cooking' replacement steel discs of today (including Brembo Oro and OE discs) because they have a much greater friction coefficient, the draw back is because of the different material used in the rotor compared to the rotor carrier thermal expansion/contraction rates are vastly different necessitating the iron rotors to be free to expand/contract at its own rate , hence the requirement to 'float' ie be held on to the carrier by rattly bobbins. Also because sintered pads eat iron rotors carbon ceramic pads must be used (since use of asbestos was correctly banned), these were once very expensive but can now be had at £22/pair. These pads on the iron rotors are awesome. The contemporary Brembo HPK steel rotors offer the vastly superior friction akin to that offered by the iron rotors (impregnation with some compound that renders them resistant to thermal load and gives huge strength), and these are also floating to stop massive heat transfer from the rotor to the carrier, HPK are today's version of the floating iron rotors and are used in racing. The shattering of the iron discs you mention is due to the discs being used beyond its wear limit, the iron discs start life at 5.0mm and should be changed once the discs thickness anywhere on it surface is <4.5mm - the water drillings on the iron discs are chamfered at the surfaces, this is a wear indicator, if any of the holes have no visible chamfer the disc should be changed, when they are used beyond their wear limit the rotor fails through not having enough strength to cope with expansion through heat, tiny cracks appear at the edges of the holes, once these cracks grow and meet up the disc fails. So if you want the modern best solution buy HPK or if you want OE, period correct buy the floating iron - if u can find them

aye n u should buy the discs before they're gone!!

I've got a pair on my sueprlight, and I've got a spare set for when they wear out.
I don't need anymore discs.

On my other bike I've got the inferior discs from a ex works superbike racer, but they were cheaper than your discs, probably because they're inferior in every way.

You have a nice day now.

Name drop alert! Name drop alert! I like that you have spare discs even though we all know that non of us will do enough miles on our bikes to empty the fuel tank never mind get through brake discs!!

not really. the rotors came of an ex wsbk bike. standard poverty spec 12 bobbin brembo as far as you're concerned.
888 owners, you're all the bloody same. Spend all the time sucking yourselves off.
However the ignore function is a wonderful thing - I'll treat you to it.

not sure why but ouch! I don't have a spine supple enough to permit what you suggest, I have often dreamt I have but wake up disappointed. The neighbour's dog does tho'
