Brake pad & disc fault - Aston wont cover under warranty

I have a 2013 V8 Vantage that had all 4 brake pads and disc's replaced during its May 2019 annual service via my local Aston dealership, before the service I could feel some juddering through the steering column under braking. It was a big expense but that's part of ownership and I knew that it was coming! The car had done 33k miles on the road up and down the M4 and going to a super market. Averaging 4-5k miles per year.

Approx 8-9 months and 3.5k miles later, I started to get some of the same juddering under braking. Lockdown was just happening and I could not get the car to my local dealership to get them to take a look at it.

Now the UK is opening up again, the car is with my local dealer for its service and upon measuring all 4 pads and discs, the front left has warped slightly. The dealer sent the measurements and pictures directly to Aston engineering and both engineering and customer service are refusing replace the failed pad & disc under their warranty as they are telling me that it has over heated from excessive hard braking and is showing a light blue colour on the disc

The car is never taken on a track, it is my low mileage daily commuter and is not driven hard. The vantage is the sports car in the line up and you would expect that the brakes are designed to take some more aggressive driving than I have been giving it. In the previous 4 years on ownership I have not had to replace any pads or disc's. Only the front left corner has shown the fault and I would expect both front left and right to have the same issue If I had been taxing the car on a racetrack every weekend!

Has anyone else experienced this in the past? and any guidance on escalating this to Aston Martin customer service? (I have been given there number and the case owner by my dealership to take this up with them directly)

I have been a great advocate of the brand and have very much enjoyed ownership but the thought of having to spend another £3100 on new front pads and discs less than 12 months after replacing all 4 is tainting my experience considerably!

Its a difficult one as "they" dont know how those 3.5k miles have been driven and only have your word for it that they were a gentle commute and not keeping the pedal pressed after a high speed stop etc.

Were the callipers refurbed during the rotor and pad change. You may have a sticking calliper that has overheated the rotor and hence caused the warping.

On most occasions I read something like this I would say its pad deposits that need a good spirited drive to remove but you say that AM have taken them and measured the run out ?

Is it really £3100 for one new rotor ? If you dont get any traction with AM and it was my car, I`d be looking at an aftermarket solution for a calliper refurb or do it myself.

This! If you've had a warped disc twice on the same corner and it's overheated I'd be looking to have the calliper checked to see if it's seized/partially seized and so binding on the disc. As regards what AM should do, it's obviously difficult from their perspective, but I'm surprised they won't even make a good will gesture - fit it for free and only charge parts etc - and I'd question them as to why if they think it is down to excessive breaking hasn't the other front disc overheated and warped too? If the calliper is sticking, shouldn't they have notice that when they fitted the new kit - I mean shouldn't they have questioned, or wondered why a disc has warped and at least check it?

If the disk has not many miles on it I would check if it can be skimmed to level off rather than replace.

I agree that it all sounds like brakes binding. I would not expect a dealership to bother checking. As a simple test you could try jacking that side up and spinning the wheel to see if it rotates freely?

Totally agree its a difficult situation for both Aston and myself with a my word versus theirs on how hard the car has been driven.

As far as I know the calipers were not changed or refurbished during the 2019 service when all 4 discs and pads were replaced. The AM dealership has take measurements that show the slight warping so I don't think a "spirited drive" would clear out any deposits!

The £3095 is the quote from the AM dealership for 2 x new pads and 2 x new discs and the labour costs to change both front corners as I am being told they need to be changed in pairs to ensure equal braking

I will ask the dealer about a sticky/challenging caliper that could be causing a problem.

If I get nowhere with AM directly, I would now look at a 3rd party for replacement parts and labour which I expect would bring the costs down to £1500-2000 but the car has only ever been touched by official AM dealers and would ideally like to keep it that way

thanks for your recommendations

Who/which companies would usually do a levelling off of the disc's? I guess they would need to do both front corners to make them as match as possible?

I will ask the dealer to do some tests on the wheel rotation and sticky/caliper or binding

Understandable, pretty much any consumable is not a warranty item. Frustrating though as a customer. You have a clutch go after 10k miles and they are not covered either....

Their prices are full wack list prices. Numerous threads on here you can DIY your own discs n pads for under £1k. Specialists are not much more.

Id be tempted to go elsewhere, a specialist if you can, get it all checked and renewed as necessary. They might be able to skim them too and save some cash.

Any back street garage can change discs and pads on any car, except maybe cars with ceramic brakes and centre lock wheels.

Just buy the parts online from somewhere like Aston Martin bits, and get them delivered to and fitted by a local half decent garage.

I would be speaking to Bamford Rose. They are the definitive specialists. I'm pretty sure they would fix the issue for less than £3100.

There is a set on eBay for £1495, genuine AM parts and that is for the front and rear rotors and pads!!! Any competent mechanic can easily fit them, in fact you could do it yourself. AM are just taking the proverbial at £3100 for fronts only!

Am sure you will have already thought of this.

If the warped run-out is safe to resolve by skimming, but you replace with new, don't allow your old parts to be thrown away. They might possess considerable value.

If it were me, I would, as mentioned, have both discs skimmed and replace with new pads. Where in UK are you, perhaps someone can recommend independent near by if you cannot tackle yourself.

£3100.00 that's one hell of a markup.

Service at a dealer, anything else at a specialist IMO.

Sounds like the problem is with the piston or they were installed wrong (no idea how they could be though).

I'd be looking at the caliper, its far more likely its not releasing properly than a disc to go bang that quickly.
Part of the service should be see the pins greased but I suffered the same fate on my old V12 Vantage, the MD hadn't bothered and it had chiseled the edge of the carbon ceramic disc away.... joy!

My first thought was caliper as well.

I don't see any point simply replacing discs/pads again without first getting to the bottom of what's causing the problem, otherwise you'll just be back to square one again in 12 months time. It might not be of any real concern to the dealer because they'll quite happily supply you with another set next time (with free coffee, biscuits, newspaper and wifi etc..)

Agree that you need to find the route cause of the problem. Once that is done you can go to onlinecarparts and buy the front brake rotors. They are currently asking £126 for a pair! New Brembos.

Almost certainly the caliper binding. Any decent engineering business should be able to skim the discs although I would go for the onlinecarparts option.

You will also need to replace the pads because they will have also overheated if the disc has. Most large motor factors will have a good source for caliper refurbishment, quite often a company I use called Brake Engineering or Shaftec. Probably around £200.00 all in for a full refurb.

If you are really keen, and you really believe the discs and pads have overheated badly, then a brake fluid change would not go amiss because you could have boiled the brake fluid.
