I have noticed lots more dust from the breaks on my rear wheels, compared to the fronts, my thinking is surely the fronts must work harder?) the disk also have what appears to be ridges in them (IE: not a smooth surface) would I be correct in thinking that its the esp that is causing it to break the back wheels and this is causing extra wear?
I drive in traffic and get a bit heavy footed among the tagers from time to time so periodically i feel the rear shift under my butt when i gas it.

would it be better to turn of the traction control to reduce break wear?

 

I discovered why this happens recently
The traction control uses the rears A LOT
I have now worn out a set of rear pads in 13k miles whilst there is plenty left on the fronts

Luckily my S has 3 stage traction control so I can switch it to track mode and back it off

 

Rears also have dragged EBRAKE which is always touching the surface as well, that certainly does not help.

Higher quality tires will drastically reduce this issue. If you are cheap on tires, you will pay more on brakes. Michelin Pilot Super Sports are a great choice.

 

It seems that one reason could be the brake bias, front to back. Does this make sense and is it adjustable?

My last set of factory rear pads lasted 6,000 miles. My fronts are lasting 2 to 4 times that I think.

 

not sure I agree, when accelerating over bumps (tree roots under the tar or just a bad tar surface) any tyre will break traction on a dry road a slic would be the ultimate but that too would slip under acceleration on a bad surface.

how does one confirm the bias and what is ebrake? mine has cable operated park brake

 

Greg,

Tires make a big difference because they alter the ABS activation window. With significantly higher grip tires, the ABS will kick in a lot less, which means less time the pads sit on the rotors thereby improving braking efficiency and reducing wear. Also, if you are not breaking the tires loose under hard acceleration then the traction control system will NOT kick in, thereby reducing rear brake wear.

I promise you, tires will solve most of the problems.

 

Thank you for your valuable comments, I have just given it a good clean I will drive the next few days with less enthusiasm and see how it behaves

 

I had the OEM tires on and the rear brake pads lasted 6,000 miles. Changed at 18K. Went to Michelin Pilot Sports and the pads went 6,000 or so miles again. Just changed the rear pads.

No difference in my experience, but maybe it is my driving.

 

I have Michelin Pilot Super Sports in Sport Pack sizes on my car—arguably the best tire available on the market today. I also have Porterfield pads which are relatively dust free and yet the rears get dusty substantially quicker than the fronts. So, at least in my case, my empirical evidence does not support your hypothesis.

 

Get carbotechs, brake dust won't be an issue. I dusts the least of any pad (eeciqlly if you get a matching set of EBRAKE pads, which carbotech can make no problem.)

 

After two weeks of carbotechs on my car I can definitely say that they are far superior in terms of dust to the OEM pads. I do not know how to measure this or otherwise provide a metric.

However, I can say that at the end of two weeks the with OEM pads my wheels were always filthy and full of a thick layer of grimy dust.

With these at two weeks there is a very, very light amount of dusting, the wheels actually look pretty clean. I would guestimate that it is a 75% to maybe 90% reduction.

YMMV.

 

Do Carbotech have a UK reseller?

 

arnt dust free pads just harder on the rotor?

 

No, the Carbotech pads are actually much softer on the rotors and actually increase the life of the rotors. Being soft on the rotors what Carbotech is famous for, that's why I had them make a custom set in the first place long time ago.

For a street pad, 1521 is the best compound period, super low dusting and virtually zero noise. They have superior cold bite. Their only limitation is they are not meant for track use (which 99% of aston owners won't do anyways)
