brake disc on rear 197

Anybody know what min thickness back disc can be before getting them changed? Got told by demon tweeks that they need doing but people have said they are just trying to get me to spend money with them.
cheers
 
ask them to quote the specs to you...

if they are doing it right there should be readings of the wear compared to a new disc "ie new disc is 11mm and measured the worn discs are 9mm so need replacing"!
