CCM Owners, Check Your Discs!

[DB9VolanteDriver]

Based on the AMOC forum thread below, AML should be issuing a recall to perform a safety check on the CCM discs. If Lambo and Bentley had this problem, then you know that it affects AML as well.

It’s the rusting of the heads of the bolts that hold the disc to the disc hub on a 10 year old DBS.

Ten year old car requires maintenance shocker. Is that a fair summary?

Basically yes. Ten year old car with low mileage. It is a safety critical item, and expensive for an owner to address.
Something to keep an eye on but awkward to check as occurs on the back of the disc assembly.

It isn't a maintenance item. Bolts that hold the disc to the hat failing is not normal. Discs wear, but they don't suddenly fall apart. Lambo and Bentley both did a safety recall a few years ago to have the dealers inspect and replace the bolts, as needed. Seeing a DBS disc with several missing bolt heads and disc cracks radiating away from the heavily corroded remnants is quite a shocker. It appears from the recall that driving in a salt-heavy environment is the leading contributor. I'll be checking the back side of mine for sure. But I am wondering why AML hasn't issued a similar recall.

Recall Number
13V484000
Recall Date
10/17/2013
Component
SERVICE BRAKES, HYDRAULIC:FOUNDATION COMPONENTS:DISC:ROTOR
Summary
Bentley Motors, Inc. (Bentley) is recalling certain model year 2007 through 2011 Continental GT, GTC, and Flying Spur vehicles, manufactured from July 2006 through June 2010 and equipped with carbon ceramic brake discs. In the affected vehicles, the stainless steel screws that secure the brake rotors may fail after being exposed to salty conditions.

Consequence
Failure of the securing screws may result in a reduction of braking ability, increasing the risk of a crash.

What Owners Should Do
Bentley will notify owners, and dealers will replace the screws, free of charge. The safety recall began on October 22, 2013. Owners may contact Bentley at 1-800-777-6923. Bentley's number for this campaign is RE13/14.

I’d guess that for most owners with carbon ceramic brakes on their Aston are probably not taking it out frequently in salted conditions, hence probably the majority of cars aren’t going to be affected by this. Aston probably figure it’s cheaper to inspect at the annual service rather than a recall.

And in the UK https://www.check-vehicle-recalls.service.gov.uk/r...

Note it is only up to 2010/11 model year vehicles in the recall, implying Brembo have updated the specification of the bolts since then.

[KevinBird]

I agree, AML should do a recall for the cars effected?

After ten years? A decade of driving?

Yes. This is a safety issue. A recall is warranted. In the US GM did a recall on ingnition
switches that I believe went back at least ten years.
That said recalls are based in many cases on reported issues. In Aston’s case I suspect there were not as many reported issues. This does not absolve them because the same argument can be made for Bentley etc.

Ah the Ford Pinto ethics question.........

100% some 10 year old cars only have minimal mileage too, if the component construction is failing and not the component then a recall is the logical path.

Just another reason not to buy a car with such a fragile fashion accessory bolted to it.

Are these bolts available to buy from AML?

Didn't someone post on here a while back and found out that AML only sell the bolts along with the entire rotor assembly!

They are a balanced assembly bought in from Brembo hence the bolts are not really serviceable.
