Hi
I'm looking for info on the minimum thickness of a front dics. The unworn section of disc = 4mm, the worn section is 3.6mm. As far as I can work out from the internet, the minimum thickness before replacement is required is 3.5mm. 0.5mm of allowable wear doesn't seem very much, but then I'm probably comparing it to much thicker car discs where 2mm of wear is typically permitted. Any advice gratefully received!
