The importance of proper brake rotor maintenance cannot be overstated. A well-maintained brake rotor is crucial for ensuring the safety and performance of a vehicle. One critical aspect of brake rotor maintenance is measuring brake rotor runout. Runout refers to the amount of deviation from a perfect circular shape that a brake rotor exhibits. Measuring runout is essential to ensure that the rotor is properly aligned and to identify any potential issues that could affect braking performance. In this blog post, we will explore the tool used to measure brake rotor runout and the importance of proper measurement.

What is Brake Rotor Runout?
Brake rotor runout is the amount of deviation from a perfect circular shape that a brake rotor exhibits. This deviation can occur due to various factors such as manufacturing imperfections, wear and tear, or damage caused by improper installation or maintenance. Runout can affect the performance of the brake system in several ways, including:
- Reduced braking efficiency
- Inconsistent brake pedal feel
- Increased risk of brake failure
- Potential damage to other brake components
The Importance of Measuring Brake Rotor Runout
Measuring brake rotor runout is crucial to ensure that the rotor is properly aligned and to identify any potential issues that could affect braking performance. Proper measurement helps to:
- Identify and address any manufacturing imperfections or defects
- Monitor the condition of the rotor over time and identify any signs of wear or damage
- Ensure proper installation and alignment of the rotor
- Prevent potential brake failures or issues
What Tool Is Used to Measure Brake Rotor Runout?
The tool used to measure brake rotor runout is typically a brake rotor runout gauge. This gauge is designed specifically for measuring the deviation from a perfect circular shape that a brake rotor exhibits. The gauge is usually attached to a brake rotor and measures the distance between the rotor’s surface and a reference point. The measurement is then taken and recorded to determine the amount of runout present.
Types of Brake Rotor Runout Gauges
There are several types of brake rotor runout gauges available, including: (See Also: How to Change a Brake Disc? A Step-by-Step Guide)
- Calipers: These are the most common type of runout gauge and are used to measure the distance between the rotor’s surface and a reference point.
- Indicators: These gauges use a needle or pointer to indicate the amount of runout present.
- Dial indicators: These gauges use a dial to display the measurement taken.
- Laser gauges: These gauges use a laser to measure the distance between the rotor’s surface and a reference point.
How to Use a Brake Rotor Runout Gauge
Using a brake rotor runout gauge is a relatively simple process. Here are the steps to follow:
- Attach the gauge to the brake rotor
- Position the gauge so that it is perpendicular to the rotor’s surface
- Take the measurement by reading the gauge’s display
- Record the measurement and compare it to the manufacturer’s specifications
Conclusion
Measuring brake rotor runout is a critical aspect of brake rotor maintenance. Proper measurement helps to ensure that the rotor is properly aligned and to identify any potential issues that could affect braking performance.
