Rear Brake Rotor

Since rotors are made from more durable material, you only need to replace them every 50,000 to 70,000 miles. However, this may vary depending on your driving habits, any debris, and the driving conditions you encounter. If you notice squealing or grounding noises or vibrations while braking, you must replace them. In addition, inspect your rotors regularly, particularly when you replace your brake pads, for any signs of damage like rust, warping, or deep groves in the rotors. If you spot them early on, you can prevent issues in other aspects of your braking system.

Your rear brake rotors must be about 28 to 45 mm to be safe, although this may vary depending on your vehicle's manufacturer's recommendations. Any thinner and they may not be as effective in dissipating heat and keeping your braking system in working order. Thicker rotors can absorb more heat, reducing the risk of overheating and brake fade.

Warping can be caused by excessive heat from heavy braking, rapid cooling of hot rotors, or improper installation. Repeated heating and cooling cycles can cause the metal to deform, leading to a warped rotor.

Front brake rotors are generally larger and thicker than rear rotors because they handle more braking force due to the weight the front of the vehicle carries. They often have better cooling mechanisms to dissipate heat efficiently. Front rotors also wear out faster due to their increased load during braking.

Yes, high-performance brake rotors are available. Brake rotors made from materials like carbon ceramic or with drilled or slotted surfaces are better at handling higher temperatures and stopping the vehicle faster. High-performance vehicles often require these features as they may experience more braking pressure than other vehicles.

Brake rotors are typically cast iron due to the material's durability and effective heat dissipation. As mentioned, you can also use high-performance rotors with carbon ceramic materials if you want your brake rotors to last longer. However, your choice of brake rotor material may depend on your budget, vehicle manufacturer's preferences, and desired performance.

At Advance Auto Parts, our rear brake rotors range from $23 to over $1,000. The cost mainly varies depending on the materials, the make and model of your car, and how durable you want the brake rotor to be.

To replace rear brake rotors, safely lift and secure the vehicle, then remove the wheel. Next, remove the brake caliper and old rotor. Install the new rotor, reattach the caliper, and replace the wheel. Fasten all components, and test the brakes before driving.

To extend the lifespan of your rear brake rotors, practice gentle braking, avoid sudden stops, and follow a regular maintenance schedule for your braking pads and shoes. Keeping the braking system clean and inspecting components for wear can also help prolong their life.
