Folks,
Just did a search on google to check the difference between TTRS and RS3 brake discs. This brought up a page listing for our very own forum.
I dare not even try to copy the page link - but it looked genuine.
part of the address was "1539-brake-problems-read-this"
Please be careful, if I got caught it's a cert this will catch someone else.
Thankfully this hit my Mac Air (which I thought was fairly invincible) - and crashed it while running Chrome. Back up and running no problem with anti-virus but it shouldn't have happened.
Hope this is of help to someone.
