Replacement carbon ceramic discs for challenge stradale

Might be worth contacting Brembo and suggesting the way they cracked could be a manufacturing defect and what they have to say about it... Shouldn't really crack like this if fixing hardware is torqued correctly at the factory!

 

Keep the hats and find replacement donuts from another marque. Significantly cheaper option if you can find equivalent sizes. I recall from memory they where 380mm fronts and maybe 350mm rear (sorry fuzzy memory!).

.. It's tricky to remove the mounting hardware (they sometimes almost weld together with the heat) and you need to re-torque them like you would a cylinder head but it is possible.

 

There is a company in the north west of England who make CCM discs, around Liverpool i think and cheaper than OEM

They are in Frodsham in the north west of uk , no idea if any cheaper but worth an e mail.

I looked on Eurospares web site and they have both front and rears in stock from £1750 each, depends on your model as they are listing a few different part numbers.
Comes out at $Au 12 600 on my sums at 1.8 to the pound for the cheapest

 

How many miles are on the car? It is very surprising to see that. As pointed out earlier, they are torqued from the factory and shouldn't ever need to be touched again so it's disconcerting to see such uniform cracks.

 

Just hope it wasn't done maliciously by some dealer trying to get money in a unscrupulous way!

 

It looks like it’s the 1st version of the hats. I think CS’s had 2 different versions of the disc design. Maybe someone with more knowledge can provide more info on the differences??

 

Eurospares are listing a few different pt nos

 

These are different to my 430, the pins in the picture- are they a bolt with a nut on the reverse side or is that a series of riviets holding the disc to the carrier. Do you have a pic of the other side ?.
If the part that is showing the cracks is Alloy and the pin/ bolt is steel they may have corroded where they meet, so the tight clearence has become a bigger clearence. Every time you brake they are moving relative to each other. UK roads with winter salt gritting would not have helped.
No point fitting non ferrari parts as new owner would knock off price to bring back to oem

 

I wonder if you have the first generation mounting system there. Brembo redesigned to improve disc location - the later type allows fora greater difference in thermal expansion between disc and bell.

If you can provide a pic of the front face I can confirm.

 

Found a pic of the rear of the first gen discs. You do have the later type.

I'm inclined to think material defect or over-torqued fasteners. I do know it is difficult to achieve uniform quality of manufacture of the CCM discs - hence why the weight of two discs if the same type can differ so much.

 

I've never seen this happen before on any CCM'S I've dismantled, even on track abused Challenge car examples. The only way I could see it occurring is for a few reasons.

1. Manufacturing defect - hence suggesting getting in touch with Brembo to get their opinion (and hopefully good will)

2. Someone previously dismantled them ( e.g for detailing purposes ) and then didn't follow correct process to torque them back down which is done like doing a cylinder head, gradually and in sequence.

3. ...Or maliciously to deliberately make them fail so they need to be replaced at great cost. Overtightening the fasteners will result in this happening btw and one of the only reasons why it would happen with the cracking shown. This should just not happen, ever, like this....

How long have you owned the vehicle and do you trust your dealership?

 

Hi, any idea where this company has gone as this email address does not work.
Many thanks
Paul
