MACHINING
Since accurate control of the rotor tolerances is necessary for proper performance of the disc brakes, machining of the rotor should be done only
with precision equipment.
NOTE: 1 inch = 25.4mm, so if your micrometer measures in inches and the specified thickness on the disc is in millimeters, convert millimeters to
inches by dividing the specified number of millimeters by 25.4.
Example: Specification on disc is 17.8 mm.
Dividing 17.8mm by 25.4mm/in = 17.8/25.4 = 0.70 inches.
