Has anyone got any experience of this stuff?

http://www.bgprod.co.uk/AutoProducts/Speciality/86...

My Aston suffers from REALLY bad brake squeal on the rears
Numerous attempts at copper slip, plastilube, bedding in and chamfering edges have failed frown
This is a new approach that soaks a compound in to the pads themselves
Never seen that
Curious if it actually works or is a recipe for disaster?

BG Stop Squeal impregnates the brake pad with ingredients that reduce sticking between the pad and rotor.


Doesn't sound like, er, a good thing!

My brakes were squeaking as I don't do that many miles in my car and so the brakes don't really get any hard use. I found a quiet country road with no-one behind me and did an emergency stop to try and rough the discs up a bit. It fixed the problem. I'm not sure if you want to put your Aston through that though but might be worth a try... I'm assuming you get the squeal when you apply light pressure to the brakes?

tried that in both my Astons works for a few days then the squeal is back with a vengeance frown

Damn, that must be annoying. It hasn't come back on mine. Hope you get it fixed soon!

My 350Z did it, I changed the pads and applied Copper Slip, it came back with a vengeance, so I need a cure as well !

Car sounds like a Bus.

I don't know why people think an application of snake oil will stop brakes squealing. It's almost invariably caused by a mis-match between disc and pad materials resulting from "aftermarket" brake components.

Disc brakes love to squeal. Manufacturers put a lot of time and effort into finding materials which work properly on a particular car without squealing.

Fitting OEM parts will stop the problem 99.9% of the time.

Can you play around with your braking style to get around it?

I guess the key would be to be on and off smartly. That way the pads are always either off contact or held firmly, nothing in between.

It might not even be possible to apply enough pressure at the rear (brake balance) for that idea to work.

I'm not even sure my ideas right...?

Do you have genuine parts fitted?

If not then they are the first port of call.

Otherwise ask your dealer if there are any US spec parts they can order in. Either pads or shims for the back of the pads.

The Americans HATE break squeal and dust so parts are often different. They will have lower friction and not withstand high temps as well but unless you do track days or lots of very high speed braking you'll be fine.

Erm both my Astons have always had OEM pads and discs from new, ALL of the squealed wink

Good point
Though I have noticed the traction control uses the rear brakes as well, I've worn a set out in 13k miles hehe

When I had an e46 M3 I went though a period in summer where I left my Pagid RS29 tracks pads in.

These are well known for being horrendously noisy during road use.

As well as giving them a very big chamfer, I also fitted a rubber shim pad like this: http://www.driftworks.com/brake-pad-noise-reductio...

After then applying copper slip to the back of that, the brakes were basically silent.

Failing all of that, perhaps you could fit some non-OEM pads that are actually not as good and therefore less likely to squeal?
