2019 DB11 AMR - break sqeal

[MattyAMR]

Hi Everyone, new member and new purchase of the AMR. Think it is a fabulous looking and sounding car and incredible power from the V12. Had a few teething problems with bits needing repairing by dealer under warranty, but hopefully sorted and can get on with enjoying the car. The brakes have a sqeal on breaking with light peddle pressure, wondering if anyone else has had this issue and can offer advice on how to get rid of noise?

Congratulations on your purchase. Carbon ceramic disc brakes do squeal.

They all do that sir.

The OEM pads with steel brakes have a special tendency for this - it’s not just your carbon brakes.

I've not experienced it on my AM6 Vantage, but due to the silly cost of the steel OEM pads have gone with Porterfield R4-S pads for replacements.

I assume you have fewer options, other than to smile at passers by when driving through town in traffic.

I don't know if the "Italian tune-up" that works on the Vantage steel brakes also works on CCM's

Ceramic brakes have never been an option on any version of the DB11.

If the brakes have not been used very hard they glaze over and squeal a bit. You just have to bed them in properly from time to time. If you drive it for thousands of miles with only light use you may have to perform the procedure more often.

All the performance pad manufacturers have their own guides. The dealer may do it when fitting new discs/pads so that you dont return back shortly after complaining of squeaky brakes. e.g.

Correct.

Steels only.

The brakes on my 11AMR start being noisy after a week or so if I haven’t done any spirited driving, the easy way to resolve is 3 or 4 hard braking manoeuvres and the noise is gone. If it persists the pads might need cleaning up but shouldn’t be necessary.

Thanks for input and help guys, the discs are steel, I have given them a good washdown with water this morning in case there is a build up of dust. I will let you know if it stops or I find a fix.

What they probably need as well is a good work-out. Stand it on its nose a few times from 70, with the antilock scrabbling for grip. Works every time on the rare occasions my V8V starts squealing.

Lots of options to try here. If the manic braking solution does not work, you can try some, or all of the following.
Anti-squeal paste on the back of the pads.
De-glaze the pad and disc braking surface with some coarse abrasive paper.
Chamfer the leading and trailing edge of the pads.
If all this fails, then earplugs, turn up the radio, sports exhaust or a different compound pad.

MY 2019 Vantage had horrendous brake squeal, and nothing would fix it for more than a week or so. It was particularly bad when parking, embarrassingly so. My car is 'enjoyed' and only really driven on proper driving events and trips so there was no way they'd glazed over from lack of proper use, and I hit a dead end pretty quickly with any warranty claim or help from AM despite a Tech admitting it was one of the worse he'd heard.

I changed to the Porterfield pads and they cured it instantly. I really wish I'd done it sooner, I've not had a squeak from them since. These, and swapping the awful Pirelli's for Michelin PS4S, are the two best things you can do to these cars - tyre skipping fixed instantly too!

Glad to read this as these two problems are exactly what I am looking to resolve on mine.

This message is in the DB11 owner's manual:



A problem and a challenge with AM is they do not allow much information about replacement parts to the aftermarket suppliers. This severely limits the options owners have for items as common as brake replacement parts. For the very few options to owners, the available brake pads are all track level pads which lends to the noise.

Interestingly, AM does not have exclusive brembo brake systems; instead, AM went to the Brembo catalog and chose brake systems also available to other manufacturers. Once you discover what other cars use the same front and rear brake systems, it opens up an abundance of pad options. If the car is never tracked, as mine is never tracked, I was able to move to a ceramic brake pad compound that is both dust free and noise free.

Very interesting. Any more info?

DB11s us the same Brembo rear brake system as used on a number of cars, one of which is the 2010 Corvette ZR1
DB11s use the same Brembo front brake system as used on a number of cars, one of which is the 2015-19 Corvette Z06.

Same for AM6 Vantage?

[EVR]

Interested for the AM6 as well.

And why if you track the car, ceramic brake pads are not advised?

Competition brake pads (track pads) are a special compound that can more withstand the heat from constant braking at high speeds when on a track. Other compounds do not stand up to the extraordinary heat brakes see on a track and they tend to fade at those temps.

In the case of Aston and because the car is track capable and some owners do track their cars, the factory ONLY specifies a track pad. AM doesn't give options to owners who do not track the car. I am guessing they do not want the legal issues if someone installs a non track pad then tracks the car and experiences brake fade.

The pads that are not competition pads, but offer other characteristics such as no dust and no noise and do stop very well, are available for other performance cars. So, back to the DB11, if you know what manufacturers use the same brake systems on their performance cars, yet offer the options, you can fit your DB11 with those pads.

I've had Dynamic Friction Ceramic pads on my DB11 for almost 3 years now. I am a GT enthusiast so I can be driving quite aggressively, but not to the level of track braking. Braking on my car is excellent, and I have no noises, ever, and no noticeable level of brake dust on the wheels.

Can't answer for the AM6?

In this pic of my car, I had not washed the car in several weeks when I took the pic. It is garage kept, but if the pads were not ceramic the black wheels would show heavy deposits of shed brake dust and look brown.
