Do They Always Turn the Rotors During a Brake Job?

Whether rotors are turned or resurfaced during a brake job depends on several factors including the condition of the rotors, the type of brake job being performed, and the specific practices of the mechanic or shop. In this article, we will explore these key factors to help you make an informed decision.

Condition of the Rotors

The condition of the rotors plays a critical role in determining whether they should be turned or replaced. Here are some key signs:

Serious Warping: Significant warping can affect the brake's overall performance. Turning can help, but it’s important to check if the rotor has enough thickness remaining. Deep Grooves or Damage: Deep grooves or damage to the rotor surface can impact the effectiveness of the brake pads and minimize heat dissipation. In such cases, replacement might be necessary. Visible Damage: Visible cracks or excessive wear can indicate that the rotors are no longer safe to use and should be replaced.

Type of Brake Job

The type of brake job can significantly influence the decision to turn or replace the rotors. Here are the common scenarios:

Basic Pad Replacement: In some instances, especially with a basic pad replacement, the mechanic may not turn the rotors if they appear to be in good condition. Comprehensive Brake Service: A more thorough brake service might involve resurfacing or replacing the rotors to ensure optimal performance. Manufacturer Recommendations: Some vehicle manufacturers recommend replacing rotors instead of turning them due to improvements in rotor materials and designs.

Cost and Time Considerations

Turning rotors is a more time-consuming and costly process than just replacing them. Here’s how it impacts your brake job:

Time: Turning rotors takes additional time, which increases the overall brake job duration. Cost: The cost of turning rotors is higher than simple replacement. Shops may opt for replacement if the costs outweigh the benefits.

Brake Performance

Resurfacing can improve brake performance by ensuring that the pads have a smooth, even surface to contact. However, if the rotors are too thin after turning, they may not dissipate heat effectively, leading to brake fade. Here’s why:

Smooth Surface: A smooth surface allows the pads to grip better, improving braking performance. Thermal Efficiency: Thin rotors may not dissipate heat effectively, leading to reduced braking performance over time.

Conclusion

Turning rotors is not always done during a brake job. It depends on the specific circumstances of your vehicle. The best course of action is to consult with a qualified mechanic for an assessment of your vehicle's brakes. Whether you choose to turn or replace the rotors, ensuring your brakes are in good working order is crucial for your safety and peace of mind.
