What are warped rotors?
If you’re wondering what warped rotors are, this guide is for you. Warped rotors refer to a situation where the brake rotor on a vehicle deviates from an even and flat plane to cause vibrations that you’ll feel in the steering wheel. The rotating parts of the vehicle are exposed to extreme heat and cool over time. The heat generated when braking causes the rotor to change shape and form high and low spots. The rate of warping is faster if you frequently drive in challenging road conditions. If you don’t deal with warped rotors, the vibrations can get worse, and your vehicle’s brakes may generate screeching sounds that alert you to a problem.
The condition of the rotors can lead to uneven brake pad wear, and if ignored, it can cause the brake pad to disintegrate and damage the rotor. If you don’t know how to repair warped rotors, then you risk damaging the vehicle and causing an accident. It’s easy enough to fix the problem if you catch it early enough, and having knowledge of the procedure can help you save money and aggravation when you take your vehicle in for repairs. For moderate to advanced car enthusiasts, repairing warped rotors is one of the first jobs you’ll learn to love: it requires a minimal investment in tools, it’s easy enough to complete, and it can save you a lot of money in the long run.
One of the main contributing factors to warped rotors is heat. As earlier stated, when you press the brakes and the rotor is exposed to heat, it can change the shape of the rotor and create high and low spots. These spots cause an uneven surface, which, in turn, causes the car to vibrate when the brakes are applied, and there is metal-to-metal contact between the brake pad and the rotor. If you’re wondering how to identify warped rotors, you need to look out for steering wheel vibrations when braking, noises, and a slow response time when you apply brakes.
It’s worth mentioning that while warped rotors can result from heat exposure, it can also be caused by poor installation, ongoing neglect, and uneven tightening. It’s critical to ensure that you have a professional mechanic install your brakes and service them regularly to keep them in good condition. Generally, if your rotors have overheated or are corroded, they’re likely to be the cause of vibrations experienced when braking.
It’s essential to note that brakes are a vital safety feature in a vehicle, and therefore, it’s necessary to keep them in optimum condition. It’s crucial to look for signs of warped rotors and have them repaired sooner rather than later. Driving with warped rotors could reduce your ability to brake suddenly and increase the likelihood of a vehicular accident. By being aware of the warning signs, you can get the problem fixed before it gets worse.
Now that you understand what warped rotors are, it’s important to know what causes them and be able to identify the signs that indicate a problem. Any vibrations or noises when braking require an inspection of your brakes. Even if your vehicle is new, it doesn’t mean that you won’t experience difficulties with the brake system. Having knowledge of the different issues that could affect your vehicle can help you get them fixed quickly and avoid potential accidents.
Signs of Warped Rotors
Have you been hearing strange noises coming from your brakes lately? Or do you feel vibrations when you apply the brakes? If so, these are signs that your rotors may be warped. Rotors are an essential part of your vehicle’s braking system, and if they are warped, they can affect your car’s overall performance and safety.
A rotor is a flat, round metal plate that is attached to the wheel hub. When you apply the brakes, the calipers squeeze the brake pads against the rotor, creating friction that slows down or stops the wheels. If the rotors are warped, they will not be able to provide a smooth surface for the brake pads to grip onto. Instead, the brake pads will make uneven contact with the rotor, causing the vibrations and strange noises you may be experiencing.
There are several signs that your rotors may be warped. One of the most common signs is a pulsating brake pedal. This happens when you apply the brakes, and you feel a vibration in the brake pedal. The vibration can be mild or severe, depending on the severity of the warping. You may also notice a wobbling or shaking sensation when you brake, especially at high speeds.
Another sign that your rotors may be warped is uneven wear on your brake pads. If one side of the rotor is thicker than the other, your brake pads will not wear down evenly. This can cause your brake pads to wear down faster on one side than the other, reducing their effectiveness and lifespan.
In some cases, you may also hear a squeaking or grinding noise when you apply the brakes. This noise is caused by the brake pads and rotors rubbing against each other. If the rotors are severely warped, the brake pads may wear down more quickly, causing them to make this noise.
Finally, you may notice that your car takes longer to stop than it used to. If the rotors are warped, it will take longer for your car to come to a complete stop, increasing the risk of an accident. This is especially true if you need to stop suddenly, such as in an emergency braking situation.
If you notice any of these signs, it’s essential to have your rotors checked by a professional. A mechanic can inspect your rotors and determine whether they need to be repaired or replaced. Driving with warped rotors can be dangerous, so it’s essential to address the problem as soon as possible.
How to diagnose warped rotors
Rotors are essential components of your car’s braking system. When you press down on the brake pedal, the brake pads clamp down on the rotors to bring your car to a stop. However, if your rotors become warped, stopping your car can be a challenge. Warped rotors can cause your car to vibrate or pulsate when you apply the brakes, reducing your ability to slow down or come to a stop quickly, safely, and smoothly.
Diagnosing warped rotors is not difficult. The following are some signs that your rotors may be warped:
1. Brake pedal pulsation: When you apply the brakes, you may feel a pulsing sensation coming from the brake pedal. This can happen because the warped rotor makes the brake pads and calipers move in and out of the rotor’s surface unevenly, creating a pulsating effect you can feel through the brake pedal.
2. Vibration: If you feel a vibrating sensation through the steering wheel when you apply the brakes, it’s a sign that the rotors are unevenly worn. This vibration may become more and more pronounced as you continue to drive, especially at higher speeds.
3. Unusual noise: When you press down on your brakes, you may hear an unusual noise coming from your wheels, such as a grinding or screeching sound. This noise can indicate that the brake pads are working unevenly against the rotors because they aren’t making even contact.
If you’re experiencing any of these signs, it’s time to inspect your rotors. You can do it yourself or take your car to a mechanic for a professional inspection. Always take note of the symptoms and address them immediately. Ignoring warped rotors can cause further damage to your car’s braking system, reducing your car’s overall safety.
DIY Methods for Fixing Warped Rotors
Having warped brake rotors can be annoying, especially since they lead to several brake problems. However, replacing your brake rotors can be an expensive exercise, and although it’s the best solution, it may not be something everyone can afford. Fortunately, you can often fix warped rotors without having to replace them. Additionally, using DIY methods to fix warped rotors can help you save a lot of money, and it isn’t a difficult task. If you’re comfortable getting your hands dirty, here are some DIY methods to fix your warped rotors.
Remove and Clean the Rotors
The first thing you should do when you notice warped rotors is to remove them from your vehicle and give them a thorough cleaning. Cleaning the rotors helps get rid of any rust, grime, or dirt that may have accumulated, which is often a significant contributor to warped rotors. Cleaning the rotors can be done using brake cleaning fluid spray or a shop rag dipped in soapy water and following the manufacturer’s recommendations. Afterward, dry the rotor with a clean rag or allow it to air dry.
Brake Pad Replacement
Another reason why rotors may end up being warped is from having faulty brake pads with quality issues. If the brake pads are not evenly worn, they can cause the rotor to become warped. You can correct this by replacing the brake pads with new ones. To replace brake pads, jack your vehicle up, remove the wheel and use the appropriate tool to remove the caliper. The brake pad should then slide out, and the new one can be inserted.
Resurface the Brake Rotors
Likewise, when surface irregularities are the cause of the warping, resurfacing the rotor can take care of it entirely. Resurfacing the rotor is carried out by removing a thin layer of the rotor with a brake lathe to smooth it out. This process will prolong the life of the rotors, and it is an effective way to correct warped rotors. However, if the rotors are below the manufacturer’s minimum thickness specifications, they may not be able to be resurfaced and may require replacement.
Heat Treatment
This method involves the use of intense heat to correct warped rotors. It is a great option if none of the methods mentioned earlier worked. To carry out heat treatment, you must heat the rotor to a very high temperature, then cool it quickly. This process is repeated several times until the rotor becomes straight. However, this is a risky method for your car, as the heating and cooling process might alter other components of the rotor, causing further damage if not done correctly.
Fixing warped rotors doesn’t always require a certified mechanic. There are simple DIY methods one can use to fix this easily. Also, be sure to prioritize your safety while working on your vehicle and have a general understanding of your vehicle’s specifications. If the warping is severe, replacing the rotors entirely might be the best option. Otherwise, these DIY methods can help you fix your brake rotors on a budget.
