Vantage non oem brake pads

[CitySlicker]

The front brake pads on my V12VS only have 5/6mm of material left and are due a change. Aston don’t seem to have any in stock. Does anyone here have experience with substitutes? I was very happy with the brake performance and longevity of the oem pads so a similar high quality item would be ideal.

Last year I was trying to choose brake pads (for a DB9) and after some research went for Pagid. I thought they made the Aston ones. Well maybe not, because they squeal constantly. Now every time I brake, 'eeeeeeeeeeeeeeeee'. Last week I rang the garage who fitted them to ask if the pads were under warranty - and remarkably they said Pagid brakes often squeaked, and yes they could replace them under warranty, and added that Pagid might contribute to the labour cost and/or upgrade to Brembo. So the only advice I can give is 'not Pagid'!

[CitySlicker]

Oooo thanks for the heads up! I never experienced squeaky braking on the oem pads. I remember reading the cure for it is a few very hard braking rounds from a high speed to get rid of it but it doesn’t seem to work on the Range Rover which suffers from the same issue. It’s like running nails down a chalk board…

Regarding brake squeal - performance composition brake pad materials lend themselves to brake squeal.

This is an excerpt from my Aston Martin OWNER'S MANUAL that came with the car:



Since I do not track my car (DB11 V12), and only use it as a GT car and street driving, I changed my brake pads at all four corners to ceramic high performance pads which are known to eliminate brake dust on wheels, and NEVER squeal, under any circumstances.

I would not track a car on ceramic compound pads, but for all other reasons, they are superior street pads.

Over the years i tried Pagid RS-42. The OE on the VH Vantage was Pagid RS 4-2-2 and if id you didnt bed them in from time time they could squeal.

About 10 years ago I changed to Porterfield R4S https://www.porterfieldbrakes.co.uk/shop/?wpce_sea...

No dust, no squeal, and great feel

That would be my default choice for steel discs.

They don't seem to offer pads for the v12 versions which come with ceramics. Most of my driving is on the road with the odd trackday.

Having brakes that don't squeak in normal driving conditions doesn't seem too much to ask. Every other car can manage it. It's only mine that arrives at every junction whistling like a banshee. And braking down the slope into my garage past the neighbours: 'eeeeee!....eeeeeee!....eeeeee!.....' It's embarrassing.

The only aftermarket pads Ive seen for ceramic discs are Pagids ....I have ceramic on my V12V too, but not needed new pads yet

Ive been through a few sets of Pagids on a few different cars over the last 25 years and even their road oriented compounds can squeal a bit if care not taken when installing and bedding in.

With light road use they dont really get used properly and may glaze over from time to time, then you need to re-bed them in.

Eventually I thought to give Portefield a try and much prefer them, even less, near zero dust. They offer fitment for DB9 on steel discs

Do you think mine could be designed for ceramic disks and the garage fitted the wrong version of Pagid pad? It seems unlikely because they're pretty competent.

Very doubtful , the calipers are different on ceramic disc cars. RS42 is the standard road fitment on regular discs. Unless you asked for a more track orientated pad I cant imagine they would fit anything else.

If you have never done the bedding in routine I would go out early morning, find a deserted straight bit of road and follow the instructions from Pagid. It does work, but in my experience did not last forever. Depends on how you use the car.

Well, they were fitted last May and were fine for a couple of months. But over time it's got worse and worse. The car is just used for normal driving. Nobody mentioned a bedding in routine; after about 3,000 miles I'd have thought they were...

Anyway, it's going back in next month so we'll see what happens!

I’ve got the same issue with a Bentley.

I think the problem could be that manufacturers are trying to move away from asbestos.

I wish I had just paid the £3k Bentley was asking, so that I could make it their problem.

That was something the garage mentioned. Google suggests asbestos was dropped in the 1990s.

But it doesn't explain why all cars don't now squeak. It's worst at slow speeds and when stopping.

Same issue as with the Bentley.

It's also weather dependent. When the weather is warm and dry it is worse.

Have you checked the shims have been put back on the new pads?
A bedding in procedure is a must, as previously mentioned.

I’ve was very tempted by the Porterfield pads, but I’ve just received the Hawk HP 5.0 Street pads which will be fitted on Monday. They are for my 2012 V8 Vantage S. I’ve got a couple of fast road driving trips through Europe and one in Wales coming up, plus a trip to the Nurburgring, so I thought they might be a good choice for all round use. I got them from Rich at Red Pants, Japan. I can’t comment right now but I will soon.

You would hope the garage has fit the anti squeal shims, maybe use to ceratec anti squeal paste too, that can help. I also used to chamfer the leading edge of the pad before fitting. its most annoying to fit correctly, bed them in and then still get squeal later.

Its not a new thing, ive experienced myself on those Pagid pads since I fit the first set of RS42 on my Elise in 2004. Just happens that Aston chose pagid for their OE supplier.

Lots of great info here https://aston1936.com/2019/10/21/bedding-in-oem-br...

Interesting article, thanks. And pretty shocking to read. I had three TVRs - 'high performance' cars, but the brakes never squealed. How about a BMW M5, a Merc AMG - all very fast - guess they must all squeal too.

On bedding in I found this: https://cdn.prod.website-files.com/6731cc913715472... It reminds me of the famous misfire counter activation procedure, except that now I have to get to 110mph and then brake hard to 40mph five times. I'm sure Plod will be understanding when I tell them it's in the instructions.

I see they are available 'pre-bedded-in'; that would seem to be the answer to preserve one's life and licence. Or would 3,000 miles of normal driving count as bedding in? Perhaps not.

I would just like some fking brake pads that don't squeal. Am I asking too much?

Just fit the brembo pads

https://www.bremboparts.com/europe/en/catalogue/as...

I had OEM pagid and they squealed terribly, changed to Brembo and no brake squeal, plus cheaper.

I have had squeaky Brembo.
