DB11 V8 steel brake discs

[JW5]

Hi all
I have a slight edge lip on mine & have been told by my local AM dealer that they need changing. I’m looking for supply only prices, £500 each for the rears seem to be the going rate & can’t readily see prices online for the fronts.
Has anyone made the purchase already if so where did you buy them from?
I’ve got new Porterfield pads ready to fit & hopefully they’ll cure the irritating squeaky brakes.

Hi,

Sorry cannot help with the discs but a quick comment about the pads and squeaky brakes.

I have a DB11 V12 that I purchased preowned. It needed brakes so I changed pads both front and back the first week I owned the car. In over 18 months of ownership now I do not have squeaky brakes at all so puzzles me why it seems to be a universal complaint.

Not related, the other day I was perusing the owner's manual and found this excerpt which I thought was odd the manufacturer would readily admit, and appears the universal complaints about brake squeal is normal:



In my case, I do not track my car. My use is just a nice GT car, so I opted for brake pads that would produce less brake dust on the wheels, yet provide adequate braking under all circumstances, but not optimal for the aggressive braking needs on a track.

I can’t help you with suppliers (eBay and Lithuania may be your friend) but did the garage give a disc thickness? The disc thickness I would suggest is the real indicator to replacement.
Having replaced a couple of sets of rotors on my DB9 I do question the minimum thickness quoted, no doubt there may be some thermal issues but there is a huge amount of material left before you get anywhere near to the ventilated section of the rotor (I am not suggesting you go to the vents).

I would not have thought a minor lip would be a problem to removing the existing pads.

I guess you could, depending on your workshop facilities whip the rotors off and mechanically remove the lip. Should you do this, then the caliper bolts must/ should be replaced ( having seen the price of them compared to previous models they must be made of unobtainioum).

There is quite a lot of info regarding Aston brake noise available on Pistonheads.

If the brake pad bedding in procedure on a DB11 is the same as previous models then there is a set routine to be followed, whether this applies when using Porterfield pads I do not know.

Just bought rear discs for my 2020 Vantage from Exotic Auto Parts. OEM parts at less than half of what the dealer charges. I paid $544 each.

It's a get-out clause - better to admit it than have to change disks/pads under warranty for possibly no improvement.

I chose Pagid pads for my DB9 recently and they often squeal at very low speeds. Disappointing really as it makes the car sound badly maintained.

Yes, completely agree with you about the "get out" clause.

So do all 'high performance' cars have squeaky brakes?

It's only a steel disk and a pad isn't it? Or is it special squeaky steel for extra braking?

They do. A big complaint for M car owners with big steel brakes. Same with Porsches. Mostly comes down to driving style. I have the Porterfield on my VH as it had become embarrassing, those pads cured it. My new one has no squeal thank goodness.
