AM brake cost

[klee168168]

I got a quote from the AM dealer today regarding brake pads for v8v. Says for 2013, for some reason the price of the brake pads increased from 2012 but only for the front pads. He does not know why. Front pads are $1650. Rear pads are $695. Labor is $360 for front and $360 for rear. Sensors are $138 for front and $150 for rear. Normal?

Does anyone have more reasonably priced shops? I am in Orange County located in Southern California.

there is a thread on here if you search for it that gibes prices & suppliers

or try Redpants for the porterfield pads

Normal for main dealer prices.

Search on here and shop around, buy your own parts and either DIY or take to your favorite trusted local garage.

With a bit of effort you should be able to have oe spec discs and pads all round for 1750 (fitted) USD based on UK prices I paid.

If wear sensors are in decent condition no need to replace btw.

How do I know if I have 4 or 6 pistons? I have 2013 model.

Anyone try the porterfield R4-S can comment on performance vs oem pads?
I just got the car a month ago so not sure which shops are great around here. Would love recommendations if there are local owners that do not use the dealer. Does anyone have a recommendation for independent shops that know Astons to install in the southern California area by chance?

Porterfields are great, a popular aftermarket choice

2013 model has the larger brakes, when you order the pads they are quoted 2006 to 2012 or 2012/3 onwards ...check Richs site here for advice too https://www.redpants.lol/

A lot of US Aston owners are on 6speed you may get some local garage recommendations there https://www.6speedonline.com/forums/aston-martin-3...

That's very steep!

In the UK you can get a full set of OE discs and pads (4 pot calipers though) for shy of £1,000 from Aston Martin Bits.

Then it's just labour from any decent garage - changing an Aston's brakes is no different to any other car really.

Never had to replace pad wear sensors either in 11 years.

When I change brakes on my bmw, shop recommends to change the brake sensors. I wonder why?

So they can charge you £25 each for the sensors,...as per AM dealers

I have done my own brakes the last couple of times on 2 different Vantages. On both times the sensors were not worn or damaged and swapped over fine, saving £50 per axle.

If you let the brake pads wear until the sensors come on (warning light on dashboard) then you do need to change them.

[Shinjuku79]

And also because sometimes when removing a wear sensor it gets damaged. This can't be predicted in advance. In that situation unless parts in stock the garage has a problem. So they are incentivised on another front to say change them as it avoids a headache for them / the need to carry more inventory.

Hi, please be careful if you have the 380mm discs (6 piston calipers) with the two-piece discs version (fitted together with screws), there the porterfield an many other aftermarket brake pads will not fit ! Ask me how i know ......

The Porterfield R4S are very good, i use them too, but they only fit with the newer disc versions (co-cast).

Yup I had this, brittle things they are, just tied them to the side until I could get the one part as the other came out ok.

I have the six piston front brakes on my 2013 V8 Vantage. What do you mean the Porterfield will not fit? It’s mode # AP1291 for the front pads from what AP Velocity told us.

[V8 Roadster]

The Portefield 1291 are bigger than the OEM, so thhat there is not enough space between pads and disc if you have the 2-piece discs. With the co-cast disc it fits.

The wearsensors do not fit exaktly the same position and you need to adjust the spring plates.

Not so!

On a BMW the ECU measures the resistance of the sensor and if you do not replace the sensor, which the ECU will detect as having a different resistance, it will not allow you to reset the wear indicator and estimated wear on the pads. Also, if you replace the pads too early, it messes with the system and even with new pads and loom, will not allow you to reset.

Its a manufacturer scam, not the dealers.

I was talking about not replacing sensors that have not been activated i.e. unworn, you have not let the pads get low enough. At least on the Aston this works with the simple sensor on the Aston that does not contact the disc until the pad is nearly worn out.....

So on a BMW is the wear sensor in contact with something all the time measuring pad thickness ?

[bignoise]

out of curiosity can the two piece discs ie 2012.25 my be replaced with cocast items from the later cars as these are significantly cheaper ?

yes they are, well I think not when absolutely new but soon afterwards then it advises on life using their CBS system, I know the pain of trying to get an F11 to reset, absolute nightmare even with new sensors

Hi,

yes, they can be replaced by the newer, cheaper version without problems.

I have a 2011 V8 Vantage S with the 6 piston caliper/380mm two piece rotors and use the Porterfield RS-4 with no issues whatsoever! Ive had then since last August! Yes the gap is small but it doesn't rub. I love these pads. Much better than the OEM ones. Less brake dust and absolutely no noise! You can still use the front pad wear sensors but the rear sensors will not work. If this is an issue for you then the RS-4 isn't the pad for you. In reality the rear sensors aren't as big of a deal as the front sensors. The front pads will wear much faster.
