Where To Find Your Minimum Rotor Thickness?

Looking to machine/cut your brake rotors or worried they’ve worn too far?

You’ll need to know the minimum thickness. The rotor’s minimum thickness tells you the minimum operational level of your rotor. This level can be found engraved on the sides of the rotor, within the veins of the rotor, or on the hat of the rotor.

Use a micrometer at the thinnest point on the surface of the rotor where it meets the pads to measure the minimum operational thickness. If your rotor needs to be cut or has worn passed this thickness, you’ll need new rotors.

You may also discover your rotor has Disc Thickness Variation. DTV could be the sign of a bigger problem within your brake system.
