Just a quicky!
 

Hi all
What is the front disc thickness on a 748R to start with - just trying to gauge how much wear I have left - I know its 4.0mm minimum.

If you look at the disc mounts there should be a stamp that tells you the minimum thickness of the disc before you have to change them.

not sure but I think they may start out as 4.5mm, I have a couple of sets at home so easy enough to check sometime to see what mine currently are, not much wear on one set so should be a good indicator

4.5mm ............... wear limit of 4mm
