Fresh pads hasnt fixed my high pitched squeaking. How do you know when rotors are worn out? They look a bit shiny but otherwise fine, no deep grooves. Verniers measures them somewhere between 1.5 and 2mm wide, non digital so hard to tell exactly
slightly offtopic: How to measure sub-mm:
I'm really struggling to wrap my head around this...why have they picked the twentieth line? Do none of the other lines on the minor scale line up?
The line they claim is the 22mm line is in fact the 23mm line.
