Should I replace all four brakes and rotors?
The short answer is: it depends. Replacing all four brakes and rotors at once is generally recommended, but the decision ultimately depends on the condition of your vehicle's braking system. In this article, we'll explore the factors to consider when deciding whether to replace all four brakes and rotors or just the worn components.
When to Replace All Four Brakes and Rotors
As a general rule, it's best to replace all four brakes and rotors at the same time for a few key reasons:
- Consistent Braking Performance: Replacing all four brakes and rotors ensures that your vehicle's braking system is balanced and provides consistent, reliable performance. This is especially important for safety and handling.
- Wear and Tear: Brakes and rotors wear down over time, and if one set is significantly more worn than the other, it can lead to uneven braking, pulling, or other issues.
- Longevity: Replacing all four brakes and rotors at once helps extend the lifespan of the entire braking system, as the new components will wear down at a more even rate.
Additionally, many mechanics recommend replacing all four brakes and rotors as a preventative measure, even if only one set is visibly worn. This helps ensure that the braking system is operating at its best and reduces the risk of future problems.
When to Replace Only the Worn Components
In some cases, it may be acceptable to replace only the worn brakes and rotors, rather than all four. This is typically the case if:
- One Set is Significantly More Worn: If one set of brakes and rotors is significantly more worn than the others, it may be more cost-effective to replace just that set.
- Recent Replacement: If you've recently replaced the brakes and rotors on one axle, it may not be necessary to replace the other set at the same time.
- Budget Constraints: Replacing all four brakes and rotors can be a significant expense, and in some cases, it may be necessary to replace only the worn components due to budget constraints.
However, it's important to note that even in these cases, it's generally recommended to replace all four brakes and rotors at the same time to ensure the best possible braking performance and longevity of the system.
Conclusion
In summary, while replacing all four brakes and rotors at once is generally the best practice, there may be some situations where it's acceptable to replace only the worn components. Ultimately, the decision should be based on the specific condition of your vehicle's braking system and your personal circumstances. If you're unsure, it's always best to consult with a qualified mechanic for their professional advice.
Can I just replace two brakes?
You can replace your brake pads in pairs (the front or the rear) at the same time or separately. If your front brake pads are in need of repair or replacement, your mechanic can fix this issue independently. It's also important to note that your front and rear brake pads wear at very different rates.
How much does it cost to replace all four brake pads and rotors?
Just pads, or more?: Sometimes when a vehicle needs new brake pads, it needs new rotors as well. If your vehicle does indeed need both of these replacements, it will be $250-$500 per axle — or $500-$1,000 for the entire vehicle — to replace both the brake pads and rotors.
How do I know if my rotors are bad?
Some common symptoms of bad rotors include vibration or pulsation in the steering wheel, high-pitched squealing noise when braking, shaking steering wheel, brake pedal pulsing, vehicle taking a long time to stop, loud bangs while braking, large edges on the outer part of the brake rotor, and scratch marks on the rotor.
Should you replace all brakes and rotors at once?
While more expensive upfront, replacing pads and rotors together will help both components last longer and ultimately give you the best brake performance. Replacing the full brake set also tends to be safer, as there is less risk of uneven wear or warping - both of which can reduce your stopping power.''

How to tell if brake rotors need replacing?
The 10 most common signs that you may need new rotors include:
- Squealing sounds from the brakes.
- Longer stopping time.
- Steering wheel vibrates when braking.
- Brake pedal pulsates when braking.
- Banging sounds when braking.
- Scratched, scored, or grooved rotors.
- Large edge on the rotor's surface.
- Blue color on rotors.
Is it okay to just replace brake pads and not rotors?
Yes, you can replace just the brake pads if the rotors are still in good condition, with no warping, deep grooves, or excessive wear. However, if the rotors are damaged or worn, they should be resurfaced or replaced to ensure optimal braking performance and prevent uneven wear on the new pads.
Do I have to replace all 4 brakes?
Typically, you should have both your front brake pads replaced at the same time, and your rear pads replaced at the same time, to ensure proper braking power. Of course, to make it easier on yourself with one simple visit, rather than two to four visits, you may want to replace all four brake pads at the same time.

Why do mechanics always want to replace rotors?
Rotor replacement frequency is influenced by rotor quality and driving conditions. If a mechanic identifies rotors as warped or excessively worn, they'll advise replacing them with new brake pads. Alternatively, resurfacing rotors is an option but may reduce their durability and accelerate brake pad wear.
