I don't know what constitute copyright infringement so I will verbally state the diagram.
the pin area of the tool is resting on the oval rim at the outer metallic surface of the pad and the tip of the needle is hitting the rotor surface.
with this setup, you are to read the indicator on the tool.
if you push the rod into the tool flush with the surface of the pink sleeve, what is the reading?
or conversely, if you move the plunger such that the tool registers 3 mm, how much does the needle stick out
thanks
