I thought about that, but figured the ones on the porters would be plenty, I think I threw the stockers away. I do need rotors, so I'm sure that part of the problem too..

 

The Porterfields have been absolutely silent on mine (the OEMs were doing that annoying low speed squeaking). I also transferred over the OEM shims however (based on recommendations in a previous thread, a post by KF IIRC wherein I also found the recommendation from him for these pads - Props to KF again), and there was liberal application of a copper-based anti-sieze in the process.

The Porterfields are not dustless by any means but certainly less than OEM and they performed great at a couple track days.

 

Ive owned a V12V for almost 2 years and my brakes which are carbon fiber, always make that horrific high pitched squeal. Only when i get them nice and hot does it stop, but living in NYC, thats basically impossible. Ive learned to live with it sadly.

 

I called Porterfields for information on the appropriate R4S pads for my 2012 V8VS. They were not able to give me a part number for the pads for the S. For those who have switched to the Porterfields pads on a Vantage S, I would appreciate information on the appropriate Porterfield pads. The dealer tried to fix the squeal on the OEM pads twice including the blue paste, but he noise is starting to come back.

 

Wow, that's a lot to have to live with.......all that technology and can't utilize it. I suppose that's a lot to ask living in LA. Isn't much better where I live. I want to move to Montana for pete's sake.

 

I think I posted this before...but here goes again...

Brake squeal is caused by high-speed vibration of the pad as it contacts the rotor. The pad on many performance cars fits loose in the caliper so that when you get on the track and expands from the heat, its perfect in the fitment (and no squealing on hot brakes, have you noticed?). When cold, they fit loosely in the caliper. So, all attempts to fix a squeal have to do with isolating the movement of that pad within the bracket. Shims, goop, spring clips, etc. can all do that to some degree but are only moderately successful. You bought a performance car that was set up to be driven aggressively with hot brakes and noisy brakes are part of that equation when they're cold.

Solutions?

1) Change pads. Different makers have different tolerances. You want a pad that fits tight in the caliper.

2) Smile when you hear 'em squeal, knowing that its a sign of a car built for extreme driving.

3) Buy a Lexus LS.

 

I just went through this problem a few days ago with a replacement set of rear pads. I installed a set of EBC redstuff brake pads on the rear and boy did those things squeal like a pig every time I touched the brakes. It was so loud, I swear you could hear it a mile off! Come to find out, I needed the factory Aston Martin shim kit that has these claws that go around the brake pad to grip it (prevent vibration). Once I redid the job and installed these shims the noise was gone. If in fact you have these shims installed than you need the noise isolater kit that can be purchased through Aston Martin, part# 4G43-28-10789. Hope this helps.

 

The EBC pads on the DB are HORRIBLE...no doubt. I did pads and rotors last year and learned a ton. I had the red stuff in there for a couple of weeks. Frieght trains were quieter than my Aston. I kept the factory rear parking brake pads stock I got from the dealer along with factory rotors from the dealer also, BUT on the the main pads I swapped over from the EBC to the Porterfield R4S (after only a few weeks of using the EBC I couldn't take the noise anymore, I have a race car I know what racing brake pads sound like and the EBC were not normal) and anti squeal gel w provided shims...and voila, great braking, low dust, and quiet performance!

 

I was able to make the EBC redstuff work just fine with my setup. Are you sure your mechanic had the correct shims and noise isolators installed?

 

^^^ I dunno I think he used the supplied shims which for the Porterfields worked just fine. He used a brake squeal paste also and the setup has been great. I ddin't know the factory p/n when the job was done...

 

One trick with brakes squeal on the Astons is NOT to use copper based anti squeal use the blue elastomer based stuff
A senior factory tech came to look at my car at the last service. We talked about brake squeal and he explained the copper compound washes away and hardens off, the blue stuff doesn't, it also damps the resonance of the pads on the discs better.

Worked on my last Vantage, not done it yet on the new one but it needs it
