Brake Dust Problems

[JFX5]

Hi,
I just got a 2005 X5 3.0 for my wife a few days ago....Overall, I'm very impressed with the car. We drove a bunch of the competitors before choosing the X5....LR3, new ML, Lexus etc. I found the X5 outclassed them all, which is no mean feat given the fact that all of the other cars are new models compared to the X5!

I really only have 2 complaints....I think the stereo is pretty lousy (very thin sounding with zero depth) I tried the DSP version & frankly it wasn't any better, and I have never owned a car that generates the amount of brake dust the X5 does (I have a 2005 Porsche 997S and by comparison it produces about 90% less dust)....It's absolutely absurd!!! In fact it's so bad that I'm going to have too change the pads. It seems that the Axxis Deluxe pads are the way to go....Do I need to change the front and back pads (I can live with the rear brake dust levels) Is it bad to have different brands of brake pads front and rear.

BTW this is an incredibly informative website....the how to articles have proved invaluable. Although the car we got was pretty loaded , I find myself wanting to add bits and the forum articles have been a great step by step guide on how to perform mods.

Thanks for the help
Jason
