How do you check brake rotor thickness?
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.
How do I know when my brake rotors need replacing?
It could represent four signs that it’s time to replace your brake rotors.
- Vibrating Steering Wheel. If you feel pulsing in the brake pedal and vibration in the steering wheel when you slow down, your rotors could be signaling trouble.
- Intermittent Screeching.
- Blue Coloration.
- Excessive Wear Over Time.
What tool is used to most accurately measure the thickness of a brake rotor?
This micrometer is used for precisely measuring thickness of brake rotor surfaces. It provides accurate, quick measurements.
Which things are important to check when measuring rotor thickness to determine if they need replaced?
Measuring Rotor Thickness. It’s impossible to tell how much life is left on the brake rotors by simply looking at it.
How do you know the rotors are bad?
Pay attention to what you feel while driving. One of the most common indicators of worn out brake rotors is rattling, wobbling, or shaking while braking. These vibrations are normally felt through your foot as you apply the brakes, and it is usually indicative of brake rotors that have become warped.
How do you know if rotors are bad?
What is the minimum rotor thickness?
Since 2010, the 1.5mm minimum recommended rotor thickness has been printed on Shimano rotors. As for your specific rotors, that’s the least easy information to find.
How is the thickness of a brake rotor determined?
As the rotor reaches its minimum thickness, the braking distance increases, sometimes up to 4 meters. Rotor Minimum Thickness is determined by the motor Vehicle Manufacturer during the initial vehicle design (also refer to AUSTRALIAN STANDARD 3617:1997) A brake system is designed to take kinetic energy and transfer it into heat energy.
How are the brake pads and rotors related?
The piston movement forces the brake pads in contact with the spinning rotor. Rubbing between the brake pads and the brake rotor generates heat which is then dissipated by convection (i.e. hot air rising from the surface of the disc rotor) into the atmosphere.

What should be the thickness of a front disc?
The new thickness for fronts should be 28.05mm and a suggested minimum is 25.00mm. That is for the standard 296mm front discs, however, not the upgraded 330mm discs.
