How do I measure my bike rotor?

Rotor size is measured by diameter, ie. edge to edge through the centre. The size may also be etched on to the rotor which would be more accurate than measuring yourself. There are a number of common IS (International Standard) sizes of rotor from 140mm through to 203mm.

What size are my rotors?

Call your local OEM dealer and ask for the original rotor sizes or OEM rotor/pads part numbers based on your vehicle’s VIN number (VIN# is referenced in your ownership papers). The dealership may not tell you the rotor size, but they will give you the genuine part numbers for your vehicle.

How do you measure the width of a 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.

Does the size of the rotor matter?

You can exchange brake pads, experimenting with different material compounds for feel and durability, but rotor size has a much more significant influence on absolute brake performance. … The more heat your brake rotors can absorb, the longer they’ll retain stopping power, without fading.

Are all rotors the same?

Unfortunately, there’s no way to judge the quality of a rotor by its appearance alone. An economy rotor may appear to be nearly identical to a premium-quality rotor, but the metallurgy is often far different. There are many different grades of cast iron, and some make much better brake rotors than others.

What are the signs of bad rotors?

Be on the lookout for a pulsation or vibration in the vehicle or on the brake pedal. You may even feel this vibration or pulsation in your steering wheel. If you experience vibration or pulsation, it is an indicator that the rotors could have a thickness variation problem and should be checked.

What does a worn rotor look like?

What do bad rotors look like? That depends on the type of wear the parts have experienced. Worn brake rotors often have distinctive score marks or grooves, which develop from the repeated pressure of the brake pads over time. Deeply grooved rotors usually require replacement, as do rotors that have become too thin.

What are the signs of bad brake rotors?

Symptoms of a Bad or Failing Brake Rotor/Disc

  • Noisy brakes. One of the first symptoms commonly associated with bad brake rotors is noise. …
  • Vibrations from the brakes. Another symptom of bad brake rotors is excessive vibration coming from the brakes. …

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.

When you measure a rotor you should?

New Rotors

Measurements should be taken a 1/4” from the edge. First find the lowest point in the rotor and set the dial indicator to zero. Rotate the rotor to find the high spot. This is the total indicated runout.

Are thicker rotors better?

3 Answers. Simply put a bigger rotor provided better braking, and a four pot caliper provides better braking – better meaning more, and more control (Everything else being equal). For the same force between the disc and pads, a bigger rotor generates more torque on the wheel – i.e. more stopping force.
