2. Attach a dial indicator to a solid non-rotating portion of the hub assembly or suspension.
The point of the styles must contact the rotor face about 25 mm (1-inch) from the rotor edge.
3. Move the rotor one complete rotation and observe the dial indicator.
4. Rotate the bezel on the dial indicator such that "0" is at the low deflection point.
The thickness of a rotor is important for two reasons:
2. Rotors worn below minimum thickness in combination with worn pads/linings can result in the caliper piston extending too far becoming
cocked or jammed.
Rotor thickness should be measured at the thinnest point on the rotor. Any rotor which is worn below its minimum thickness should be replaced.
For accurate measurements, it is best to remove the caliper to allow for complete access to the inboard side of the rotor.
