Introduction
Rotors are a vital part of your car’s braking system, working in tandem with your brake pads to help you slow down and stop safely. Over time, rotors wear down, become warped, or develop grooves, which can affect braking performance and safety. If you’re experiencing vibrations, squealing, or uneven stopping, you might be wondering: how much is it to change rotors? This guide explains the typical cost of rotor replacement, what factors affect the price, and how to tell when it’s time for new rotors.
What Are Rotors?
Brake rotors, also known as brake discs, are circular metal components attached to each wheel. When you press the brake pedal, the pads clamp onto the rotors, creating friction that slows the vehicle.
How Much Is It to Change Rotors?
Average Cost per Axle (Front or Rear):
- Parts only: $30 – $150 per rotor
- Labor only: $100 – $200
- Total per axle (parts + labor): $150 – $350
Full Vehicle (Front and Rear):
- Total cost: $300 – $700+ depending on vehicle type and rotor quality
Price Breakdown by Vehicle Type
Factors That Affect Cost
1. Vehicle Make and Model
Luxury or performance vehicles often require specialty rotors that cost more to replace.
2. Rotor Type
- Standard rotors: More affordable, basic design
- Drilled/slotted rotors: Better performance and cooling, more expensive
- OEM vs. aftermarket: OEM rotors usually cost more
3. Labor Costs
Hourly labor rates vary by region, typically ranging from $80 to $150 per hour.
4. Shop vs. DIY
- DIY: Only the cost of parts ($60 – $300 total)
- Shop: Includes labor and potential extra services like pad replacement
When to Replace Rotors
- Vibrations or pulsating when braking
- Visible scoring or grooves on the rotor surface
- Rotor thickness is below the manufacturer’s minimum
- Squealing or grinding noises
- Uneven or reduced braking performance
Should You Replace Pads and Rotors Together?
Yes. It’s usually recommended to replace brake pads when changing rotors to ensure proper bed-in and optimal braking performance.
Tips for Saving Money
- Shop around for quotes from independent mechanics and dealerships
- Consider aftermarket rotors from reputable brands
- Look for brake service bundles that include pads and rotors
- Ask about warranty coverage on parts and labor
FAQs
Can I just replace one rotor?
No. Rotors should be replaced in pairs (both front or both rear) to maintain even braking.
How long do rotors last?
Typically 30,000 to 70,000 miles depending on driving habits and conditions.
Are drilled/slotted rotors worth it?
For high-performance or heavy-duty vehicles, yes. Otherwise, standard rotors are sufficient for daily driving.
Can rotors be resurfaced instead of replaced?
Sometimes, but resurfacing is becoming less common. Many rotors are too thin or warped to be safely resurfaced.
Conclusion
So, how much is it to change rotors? Most drivers can expect to pay between $150 and $350 per axle, depending on the vehicle, rotor type, and labor costs. While replacing rotors isn’t cheap, it’s a critical part of maintaining your vehicle’s safety and braking performance. Regular inspections and timely service can help you avoid more expensive repairs down the road.
