Can we talk brake pads?
Discussion
Yes yes, I'm sure it's been covered before..... But I wanted some opinions relating to my circumstances.
About 8 months ago I picked up my first ever Aston Martin - DB9 - in Titanium Silver. Oh, it's a 2008.
When I purchased the car I negotiated new discs and pads all around. A month later the car was delivered. I was surprised by the feel of the brake pedal I have an M3 and the brakes are sharp and responsive and I don't get that feel from the Aston. At first I thought it was because the pads were new. after 2,000 Kilometres I think that they're suitably worn in.
My local mechanic suggested that the brake pad material might not be genuine and said that a change of pad might be the way to go..... Might also stop the god awful squeaking!! Next week he will pull the pads out and apply some copper grease to the back of the pads, which he says, might stop the squeaking.
What are your thoughts on brake pads? any experiences like mine? What pads will result in a brake performance more like an M3?

have a look on Redpants website about 70% down the list of blog topics

Rich has done a comparison of the Porterfield & porterfield RS pads
both produce less dust than the OEM Pagids (if that is also an issue)
I've replaced mine with Pagids & they work fine, lots of dust, no squeaking, but definitely not a "bite" when applied like my RS4 (or your M3)

just got done with a track day at Thunderhill Raceway. On my 5 hour drive home - rear brake pads low - light came on. Going to try the Porterfields this time. EBC Reds last time. I'm no racer but I could feel them fade as they heated up lap after lap. Very dirty too. But I'm seriously dreading the break in squeal. Took about two weeks last time.

BG Stop Squeal and a religious adherence to the workshop specified bed in procedure for new pads = no squealThe brakes on the original db9 are the same as my 07 V8 Vantage.
For the weight of the car I would say they are adequate at best.
AM bringing them up to date with 6 pot front calipers/larger disks eventually.
In my case a complete change of fluid helped and a change to uprated pads giving a much more solid feel to the pedal.
There are various stages of solutions from lager disks (expensive) to Brembo GT 6 pots and disks (very Expensive) .
It all depends on your use and depth of pockets.
Various people/companies have solutions and I would talk to Rich at redpants (I assume you are in USA?) as he has better experience with this.
Personally for road use I'd do what I did and live with it.

Audi were better - softer rotors (last about 40,000km of careful driving, less if driven hard) and better bite
I replaced the pads at about 45,000km on the V8V and the rotors were (JUST) within tolerance
they work well but I never get the feeling they will put me through the windscreen (which was always an option with the RS4)
havent tracked the V8V so no comment on really heavy use
where in Aus are you?

Perhaps I didn't bed them in correctly.
Do you think that if I had the pads taken out and have the stop squeak applied they would then stop squealing at me?
Sean, I use this http://www.supercheapauto.com.au/Product/DynaGrip-...Do you think that if I had the pads taken out and have the stop squeak applied they would then stop squealing at me?
It’s a pretty easy DIY task to get the pads out and apply. You could then do the bed in procedure again and I would imagine you should get a reduction in the squealing noise.
PM me if you don’t have the bed in procedure details.
Ps. All my comments are related to reducing the break squeal, not improving the braking performance. As most people here have commented, the standard early DB9 brakes leave a lot to be desired...
It is said that the Aston brakes do need to have the pedal pressed hard as they are not heavily servoed, but that when pressed hard they stop the car well. Perhaps I'm staying the obvious but it may be a difference in braking set up and, whatever pads are put on, that won't change the characteristics of how the braking system operates.
Iirc the oem pads are pagid 4.2.2 - these are known as a good performance pad and the cost of that performance is the dusting.
