How to replace brake rotors?

Brake rotors are metal parts that are attached to the wheels of a vehicle. They are a vital part of your braking system. They are attached to your wheels and are what your vehicle's brake pads press against to keep your wheels from spinning and help you avoid accidents. When the driver depresses the brake pedal, the brake pads come into contact with the rotor, creating friction that slows the car.

Replacing brake rotors depends on mileage, driving conditions, atmospheric conditions, and the driver's driving habits.

Although replacing your rotors is a relatively simple task, there are a few steps to follow and you need to make sure everything goes smoothly. Read this article to learn how to replace your car's brake rotors.

What are brake rotors made of?

Brake rotors are made of a high-strength alloy of steel and cast iron that can withstand the high temperatures associated with brake pad friction on their surface. Brake rotors are considered consumables and should be replaced every 60,000 to 80,000 miles on average. Of course, this also depends on your driving style. New rotors and a new set of pads will provide excellent braking performance.

When should I replace my rotors?

As you already know, brake rotors wear out over time, making your car more dangerous to drive. That's why it's important to replace your rotors when you notice..:

Noisy brakes

Noisy brakes are the first sign of rotor wear. If the disc is uneven, you'll hear squealing coming from the wheels. Warped rotors produce a squealing sound, while extremely worn rotors produce a scraping sound. You'll need to disassemble the wheel to determine whether the pads or the rotors are worn, as both produce a squealing sound. It's dangerous to drive with worn disc brakes.

Wheel vibration

Squealing is often accompanied by excessive vibration of the worn brake rotor. If the wear is excessive, you'll feel it in the brake pedal. Deformed rotors can also cause the brake pedal to pulsate when depressed. This is because the pedal is no longer in contact with the rotor. Driving with vibrations can be dangerous.

Grooves on brake rotors

Worn brake rotors often have grooves on the sides. Brake rotors are designed to last tens of thousands of kilometers. Repeated contact with the brake pads causes the rotors to wear.

How do I replace brake rotors?

Step 1: Assemble your vehicle

To replace your brake rotors, start by loosening the bolts on your wheel. You'll need to jack up your vehicle and place it on jack stands.

Step 2: Remove the wheel

Use a torque wrench to remove the wheel and gain access to your vehicle's brake system.

Step 3: Remove the caliper.

This part is usually held in place by one or two bolts that screw into the back of the caliper. You'll need a ratchet wrench and an extension to reach these bolts. After removing the mounting bolts, remove the caliper, being careful not to pull on the brake hose. You may need a screwdriver or hammer to loosen the caliper.

You'll need to start by removing the nuts holding the caliper in place, as well as the mounting bolts.

Step 4: Remove the rotor.

Finally, loosen the screws that secure the rotor to the hub, then remove the hub from the universal joint. It will be necessary to separate the two parts of the hub in order to free and remove the brake rotor. Sometimes you'll be able to remove it easily. However, if the rotor has not been replaced in a long time, it may be rusted and difficult to remove. You'll probably need to use a hammer to loosen it.

Step 5: Clean the hub.

Use a wire brush to remove rust and dust from the pads. This step is essential: a poorly cleaned hub can cause the rotors to warp during initial braking.

Step 6: Install the new rotor

Now you are ready to install the new rotor onto the hub. The second part of the hub, the bearing and the mounting bolts must then be reinstalled.

Step 7: Apply loctite

You can apply loctite to the threads of the bolts to extend their life and prevent them from loosening, leaking, or corroding.

Step 8: Reassemble the caliper

Finally, reattach the hub to the universal joint using the nuts, followed by the caliper.

Step 9: Replace the wheel

Replace the wheels and tighten the lug nuts (by hand). Lower the vehicle to the ground and tighten the lug nuts using a torque wrench or a socket wrench with a flex handle.

Step 10: Test the disc before driving.

Before you hit the road, it's a good idea to make sure your new brake rotor is working properly. Start your car in a safe location and drive forward. Depress the brake pedal several times and let it rise gently. The brake should work properly without squealing or vibrating. Squealing indicates worn brake pads, while vibration indicates a warped rotor.

We recommend always replacing rotors in pairs (i.e., both front rotors together or both rear rotors together) to avoid uneven braking.
