My father's DBS volante was found to have a small stone jammed in the rear caliper which has scored the disc so that 'according to Aston' it is now structurally unsound.

Their quote for a replacement pair of rear ceramic discs was a mind blowing £6.5k.

Anyone know of a cheaper way of doing this?

Appreciate your input. Cheers.

IMO it would need to be one deep score for the disc to be unsafe. I would run it on and keep an eye on it.
Can you post up a few pictures of it please.

OK, so one day I'm going to upgrade to either a V8Vs or a V12V (from my 4.7 V8V). I think I will go for a V12 because they are just fab but this could be a deal breaker because you can buy a car for £6.5K (that your teenage children can crash). There are now quite a few carbon braked Astons out there for there to be some experience of this on this forum. How common is it and surely, there are cheaper solutions out there? If I were an independent brake specialist I would be working on a solution and offering it for half the price then using the profit to pay for a V12V. Just how expensive can carbon brakes be to make?

Could you not source a couple from salvage? Might be the odd written off car lying about somewhere with two perfectly good rear discs?

6.5k does seem a lot but they are meant to last the lifetime of the vehicle (subject to no stones getting lodged in them)

Picture to follow as I am really sceptical of how much damage a stone can have done.
Plus, this particular DBS never gets driven in anger so is it really going to be a problem?

Amused by the part exchange comment!

Let me get a pic of the offending disc.

Yeah, some completely unqualified people on the internet should be able to tell you if your car is safe to drive or not based on a picture from a camera phone rolleyes

If you don't like the main dealer quote, go to an independent. I really don't care what Jalfonse or Tony Hall think but I recommend Bamford Rose, they have just sourced me a complete set of CCM discs and calipers for my DB9.

CCM brake disks were £3000 each three years ago, pads £750 per rotor. At that time the disks were not sold in pairs.

Be very careful buying second hand CCM disks. They can be invisibly ruined by chemicals.

Fitting requires balancing the disk and wheel - it took AML a while to figure that out with DBS.

Seeing what has just happened to Hamilton in qualifying due to CCM failure I think Yeti speaks very wise words. It's like people who put budget tyres on (fast) cars. Completely bonkers.

Why you bringing me into this....you recommend who you like...I don't care.....
Personally I would tell the op to go onto eBay as there is a rear disc on there for about a grand.....and you should get off your high horse and be a bit more polite.....

Agreed, keep me out of this, you simply cannot post a comment without a threat, sarcasm or personal attack. You need counselling Lewis.

Apologies to OP, good luck with your issue and always get a second opinion if in doubt, remember, very few of the people you will speak to at a dealer are actually qualified engineers but all of them want your money.

Get a second opinion from a good Indy. But if it does need replacing it will be expensive and as JohnG1 says it has to be balanced with the wheel.

That implies the brake/wheel combo balance needs to be redone whenever the tyres are changed too?

Good point. Wonder what they do on the carbon disc models. When first launched there was a number of owners having issues, which eventually led to the factory balancing the disc and wheel.

Firstly, there is simply no need for a pair of discs. Buy a new (or used) one and fit it your self. It is a simple procedure to remove and replace.
And the rear rotors do not have to be specially balanced like the fronts. AM only did the special procedure when needed and only for the fronts.
Regarding balancing, the rotor/wheel are not balanced together. Rather, the wheel is balanced to offset any rotor imbalance. Once the process is done the first time, balancing a wheel due to a tire change is a simple process that does not require doing anything with the rotor. I have changed wheels/tires several times without any associated problems resulting from the rotor imbalance.

I don't understand how thus works. You're implying that a wheel, and it's position on the hub, can be balanced to correct an imbalance in the rotor - I'm ok with that. But take the wheel off, and balance standalone would remove any bias to correct the rotor imbalance. You'd need to both balance the wheel with the same imbalance and fit on the hub in the same position to maintain the correction?
