How To Tell If Front Or Rear Rotors Are Warped

If your vehicle shakes or vibrates when you brake, it may have warped rotors. Warped rotors can happen gradually over time from normal wear and tear, or they can happen suddenly if the brakes get too hot. To check for warped rotors, place a level on the rotor while the vehicle is parked and measure the height of the rotor at the outer and inner edges. If the rotor is warped, it will be higher on one side than the other.

1 Steps to Tell If Front Or Rear Rotors Are Warped

One way to tell if your rotors are warped is to inspect them for uneven wear. If you see that one side of the rotor is more worn than the other, it’s likely that the rotor is warped. You can also check for warping by feel. If the rotor feels uneven when you run your hand over it, it’s probably warped.

One of the most important skills that a driver can learn is how to tell if the front or rear rotors are warped. This is a very important skill to have because if the rotors are warped, it can cause the brakes to not work properly. If the brakes do not work properly, it can be very dangerous.

Step 1: Look For Vibrations When Braking Check If Brake Pads Are Worn Unevenly Measure Rotor Thickness Measure Rotor Runout

One way to tell if your front or rear rotors are warped is to look for vibrations when braking. Uneven wear on the brake pads can also be a sign that the rotors are warped. To measure the thickness of the rotor, use a micrometer. To measure the rotor’s runout, use a dial indicator.

Frequently Asked Questions

Can Rear Brake Discs Cause Vibration?

There is a possibility that a vibration in the rear brake discs could be caused by a number of factors, such as incorrect installation, incorrect balance, or improper torque on the wheel lug nuts.

Can Rear Rotors Make Steering Wheel Shake?

Possible causes of a shaking steering wheel are worn tires, misaligned wheels, a loose steering column, or a rotational imbalance in the wheels. A bad rotor could also cause the wheel to shake, but this is usually accompanied by a loud humming noise.

Can Rear Rotors Cause Shaking?

Yes, rotor wear can cause a vibration in the steering wheel. This is usually caused by thickness variation in the rotor or by rotor runout.


There are a few key things to look for when trying to determine if your rotors are warped. One is checking to see if the rotors are even. If one side is thicker than the other, that is a good indication that the rotor is warped. You can also check for pulsing in the brake pedal when braking, and listen for a grinding noise when braking. If you notice any of these signs, it is likely that your rotors are warped and need to be replaced.
