It is very important to know the major parts of your vehicle and their functionality. This will help you when it comes to car maintenance. You need to know the difference between front and rear rotors. A lot of people think that they are the same, but it is not the case.
Are you one of the drivers that think the front and rear rotors are the same? If yes, then you need to read this informative article to the end because I will explain all the necessary information that you need to know about both front and rear rotors.
Front rotors are larger and thicker than rear rotors, and also more expensive because the front rotors endure more wear and tear than rear rotors.
What Are Car Rotors?
Car rotors are among the essential components of your vehicle’s braking system. It is a metal disc that sits behind the wheel. Immediately you press the brake pedal, the brake pads clamp down on the rotor, which helps to slow the wheel down immediately.
Rotors can wear out after using for a long time and being exposed to the elements, that is why it is very important to check them regularly and replace them when necessary.
Worn-out rotors may cause your brakes to squeak or make grinding noises, and can even lead to reduced braking power and longer stopping distances.
If you notice any of these issues, then you may have to check your rotors, always consult a qualified mechanic when it comes to checking rotors so that they’ll be able to tell you if they need to be replaced.
How Do Rotors Work?
Car brakes are designed to use friction to slow down the rotation of your wheels. So your car brake pads create friction, and they press against a spinning metal disc (or rotor) to slow it down.
This process works because of two laws of physics:
The law of conservation of energy means energy cannot be created or destroyed, only transformed from one form to another.
And the law of friction, that means when two surfaces rub together, they create heat and resistance.
Immediately, you step on the brake pedal, hydraulic fluid will be sent from the master cylinder to the calipers. Immediately the calipers will squeeze the brake pads against the rotors, creating friction. This friction produces heat, that in turn slows down the rotation of your wheels.
The amount of force needed to stop your car depends on several factors, including:
- The speed at which you’re traveling
- The weight of your vehicle
- The condition of your brakes and rotors
- The terrain you’re on
If any of these factors change, then the amount of force required to stop will be changed. That’s why you need to regularly check your brakes and rotors so that you will be able to replace them when necessary.
How to Tell If My Car Needs New Rotors?
There are some signs that your car may need new rotors, including:
- Squeaking or grinding noises when you brake
- Reduced braking power
- Longer stopping distances
Whenever you notice these issues, it’s time to take your car to a qualified mechanic to check the rotors. They’ll be able to tell you if they need to be replaced or to give them a new surface.
Are Front And Rear Rotors the Same?
No, the front and rear rotors in your car are not the same. The front rotors are bigger than the rear rotors, and they are designed to carry out different jobs. The front rotors are designed for most of the braking power in your car, and the rear rotors help to balance out the braking and provide stability.
So, the front and rear rotors wear at different rates and need to be replaced at different intervals.
What Tools Do I Need To Replace Car Rotors?
There are several tools that you need when it comes to replacing your car rotors.
It is very easy to replace your car rotors if you understand the process, but it does require some specialized tools.
How Much Do Car Rotors Cost?
Currently, the cost of replacing your car’s rotors depends on the make and model of your vehicle. You need to pay from $100 to $300 per rotor. However, some vehicles, especially luxury cars, may cost more.
How Often Should I Replace My Car’s Rotors?
There is no appropriate time or design time when it comes to placing your car rotors. It all depends on these factors, including:
- How often do you use your car brakes
- The terrain you’re driving on
- The weight of your vehicle
- The condition of your brake pads
- Generally, you need to replace your car’s rotors every 50,000 miles or so. But, if you use your brakes frequently or drive on rough terrain, then you may need to replace them more often.
Should I Replace Brake Pads With Rotors?
It all depends on the severity of the wear and tear on your brake pads and rotors. You may replace the board brake pad and rotors if your wear is significant. But, if the wear is minimal, then you may only need to replace the brake pads.
How to Replace Car Rotors?
Follow the easy and simple step-by-step process to replace your car rotors.
- You need to park your car on a level surface, then set the parking brake.
- Now you need to jack up the car and support it with jack stands.
- You have to remove the wheel, brake caliper, brake pads, and rotor.
- Then, install the new rotor and brake pads, and caliper.
- Now refill the brake fluid reservoir and bleed the brakes according to your car’s specifications.
- Lower the car and test-drive it to make sure the brakes are working properly before taking it out on the road.
- Always clean the surface of any dust or debris with a brush or wire tool before installing the new rotor.
