Something additional: Take a look at my site:
www.texerv.com

Click the button: "Bremsanlage" http://www.texerv.com/bremsanlage.html
You'll find some informations (unfortunately in German yet but you might use a site translator i.e)
I'm trying hard on an English version of my site, and I guess / hope it will be online within the next few days.

Beste Grüße
Tim
