What to know
- When the rotor is warped, it causes the brake pads to make uneven contact with the rotor, which in turn creates a pulsation or vibration.
- This is because the warped rotor is causing the brake pads to make uneven contact with the rotor, which leads to uneven wear.
- If you’re experiencing any of the symptoms of a warped brake rotor, it’s important to check the rotors to confirm the diagnosis.
Warped brake rotors are a common problem that can lead to a variety of issues, including reduced braking performance, uneven wear, and vibrations. If you’re experiencing any of these symptoms, it’s important to know how to check if your brake rotor is warped and what to do about it.
Signs of a Warped Brake Rotor
There are a few telltale signs that can indicate a warped brake rotor:
- Pulsation or vibration in the steering wheel or brake pedal: This is one of the most common symptoms of a warped rotor. When the rotor is warped, it causes the brake pads to make uneven contact with the rotor, which in turn creates a pulsation or vibration.
- Uneven brake pad wear: If you notice that one brake pad is wearing down more quickly than the other, it could be a sign of a warped rotor. This is because the warped rotor is causing the brake pads to make uneven contact with the rotor, which leads to uneven wear.
- Reduced braking performance: Warped rotors can reduce braking performance because they prevent the brake pads from making full contact with the rotor. This can lead to longer stopping distances and reduced braking power.
How to Check for a Warped Brake Rotor
If you’re experiencing any of the symptoms of a warped brake rotor, it’s important to check the rotors to confirm the diagnosis. Here’s how to do it:
1. Remove the wheel: Use a jack and lug wrench to remove the wheel from the vehicle.
2. Inspect the rotor: Look for any signs of warping, such as uneven wear or a wavy surface. You can also use a dial indicator to measure the runout of the rotor. The runout is the difference between the highest and lowest points on the rotor. If the runout is greater than 0.002 inches, the rotor is warped.
What Causes Warped Brake Rotors?
There are a few things that can cause brake rotors to warp:
- Overheating: When the brake pads rub against the rotor, they generate heat. If the rotors get too hot, they can warp. This is why it’s important to avoid riding the brakes for long periods of time.
- Uneven wear: If the brake pads are not making even contact with the rotor, it can cause the rotor to warp. This can be caused by a variety of factors, such as worn or damaged brake pads, a seized caliper, or a bent axle.
- Manufacturing defects: In some cases, brake rotors can be warped from the factory. This is a rare occurrence, but it is possible.
How to Fix a Warped Brake Rotor
If you have a warped brake rotor, there are a few options to fix it:
- Resurfacing: Resurfacing is the process of grinding the rotor down to a smooth surface. This can be done by a mechanic or by using a brake lathe.
- Replacement: If the rotor is too badly warped, it may need to be replaced. This is a more expensive option, but it is the only way to ensure that the rotor is completely flat and free of warpage.
How to Prevent Warped Brake Rotors
There are a few things you can do to prevent brake rotors from warping:
- Avoid overheating the brakes: This means avoiding riding the brakes for long periods of time. If you have to brake hard, try to do it in short bursts.
- Make sure the brake pads are making even contact with the rotor: This means having the brake pads inspected and replaced regularly.
- Inspect the rotors regularly: If you notice any signs of warping, have the rotors checked by a mechanic.
Wrapping Up: Keeping Your Brake Rotors Healthy
Warped brake rotors can be a nuisance, but they can also be dangerous. If you’re experiencing any of the symptoms of a warped brake rotor, it’s important to have the rotors checked and repaired as soon as possible. By following these tips, you can help prevent warped brake rotors and keep your brakes working properly.
Quick Answers to Your FAQs
Q: How often should I check my brake rotors?
A: It’s a good idea to have your brake rotors inspected every time you get your brakes serviced.
