When it comes to maintaining your vehicle’s brakes, there are several important steps to take to ensure your safety on the road. One crucial aspect of brake maintenance is replacing brake pads, but many car owners wonder if they also need to resurface the rotors at the same time. In this article, we’ll explore the importance of resurfacing rotors when changing brake pads, and provide guidance on when it’s necessary and when it’s not.

Why Resurface Rotors?
Rotors are a critical component of your vehicle’s braking system, and over time, they can become worn down and develop a rough surface. This can cause vibrations when you press the brake pedal, and in extreme cases, can lead to uneven brake wear and reduced braking performance. Resurfacing the rotors involves removing a small amount of metal from the surface to smooth it out and restore its original shape.
The Benefits of Resurfacing Rotors
- Improved braking performance: By resurfacing the rotors, you can ensure that your brakes function properly and provide consistent stopping power.
- Reduced vibrations: A smooth rotor surface can eliminate vibrations when you press the brake pedal, providing a more comfortable driving experience.
- Extended brake pad life: When the rotors are smooth, brake pads can wear evenly and last longer, reducing the need for frequent replacements.
- Saved money: Resurfacing rotors can be a cost-effective solution compared to replacing them entirely, which can be a more expensive and time-consuming process.
When to Resurface Rotors
Not all brake pad replacements require resurfacing rotors. However, there are certain situations where it’s necessary to resurface the rotors to ensure proper brake function and safety. Here are some scenarios where resurfacing is recommended:
Scenario 1: Worn-out Rotors
If your rotors are excessively worn, resurfacing may be necessary to restore their original shape and surface. A worn-out rotor can cause uneven brake wear, vibrations, and reduced braking performance.
| Signs of Worn-out Rotors | What to Do |
|---|---|
| Vibrations when pressing the brake pedal | Resurface the rotors or replace them if necessary |
| Uneven brake wear | Resurface the rotors or replace them if necessary |
| Reduced braking performance | Resurface the rotors or replace them if necessary |
Scenario 2: Warped Rotors
If your rotors are warped, resurfacing may not be enough to restore their original shape. Warped rotors can cause uneven brake wear, vibrations, and reduced braking performance. In this case, replacing the rotors may be necessary. (See Also: Are Lifetime Brake Pads Worth it? Saving You Money)
| Signs of Warped Rotors | What to Do |
|---|---|
| Vibrations when pressing the brake pedal | Replace the rotors |
| Uneven brake wear | Replace the rotors |
| Reduced braking performance | Replace the rotors |
When Not to Resurface Rotors
Not all brake pad replacements require resurfacing rotors. Here are some scenarios where resurfacing is not necessary:
Scenario 1: New Rotors
If your vehicle has new rotors, resurfacing is not necessary. New rotors are designed to provide optimal braking performance and do not require resurfacing.
Scenario 2: Minor Wear
If your rotors have minor wear, resurfacing may not be necessary. In this case, replacing the brake pads and checking the rotor surface may be sufficient to ensure proper brake function.
Conclusion
In conclusion, resurfacing rotors is an important step in maintaining your vehicle’s brakes. While it’s not always necessary, there are certain situations where resurfacing is recommended to ensure proper brake function and safety. By understanding when to resurface rotors and when not to, you can make informed decisions about your vehicle’s maintenance and ensure a safe and reliable driving experience.

FAQs
Q: Do I need to resurface my rotors every time I change my brake pads?
A: No, you don’t need to resurface your rotors every time you change your brake pads. However, if your rotors are excessively worn or warped, resurfacing may be necessary to ensure proper brake function and safety.
Q: Can I resurface my rotors myself?
A: It’s not recommended to resurface your rotors yourself, as it requires specialized equipment and expertise. It’s best to leave this task to a professional mechanic or brake specialist.
Q: How often should I check my rotors for wear?
A: It’s recommended to check your rotors for wear every 12,000 to 15,000 miles, or as recommended by your vehicle’s manufacturer.
Q: Can I replace my rotors with new ones if they’re excessively worn?
A: Yes, you can replace your rotors with new ones if they’re excessively worn. However, this may not be necessary if the rotors can be resurfaced to restore their original shape and surface. (See Also: How to Use Emergency Brake? Safely On The Road)
Q: Are resurfaced rotors as good as new rotors?
A: Resurfaced rotors can be just as good as new rotors, but it depends on the quality of the resurfacing process and the condition of the rotor before resurfacing. A professional mechanic or brake specialist can assess the condition of your rotors and recommend the best course of action.
