Brake discs are crucial to the safety of any vehicle. Their integrity and proper functioning ensure that the vehicle can stop effectively and safely. However, over time and with use, brake discs can also become worn or damaged, compromising safety. A common problem is ovalization of the discs, a phenomenon that can negatively affect the braking ability. In this article, we will explore how to identify if your vehicle's brake discs are ovalized, offering a step-by-step guide to recognize the signs and take the necessary action.
What Does "Ovalization" Mean?
Brake disc ovalization occurs when the discs lose their perfectly round shape and become slightly oval in shape. This can happen due to excessive heat on the discs, which in turn deform under the effect of heat. Ovalization affects the efficiency of the brakes, causing vibrations, unusual noises and decreased braking ability.
Signs and Symptoms
Here are some signs that may indicate the presence of ovalized brake discs:
-
Brake Pedal Vibration : One of the first signs of ovalized rotors is the perception of vibrations through the brake pedal when braking. This happens because the uneven surface of the rotor repeatedly hits the brake pads, creating a vibrating feedback.
-
Vibrations in the Steering Wheel : If vibrations are also felt in the steering wheel, especially when braking at high speeds, it is likely that the front brake discs are ovalized.
-
Noises When Braking : Another common symptom is unusual noises from the brakes during use. These can range from light squeaks to grinding noises, especially if the ovalization is significant.
-
Decreased Brake Efficiency : If you notice that your vehicle is taking longer or longer to stop, it could be a sign that your rotors are ovalized and not offering maximum braking efficiency.
How to Check
To determine if your brake discs are actually ovalized, you can follow a few steps:
-
Visual Inspection : Raise the vehicle and remove the wheel to expose the brake rotor. Carefully examine the rotor for visible signs of wear, warping, or damage.
-
Using a Micrometer or Dial Gauge : Tools such as a micrometer or dial gauge can accurately measure variations in disc thickness, indicating areas of uneven wear that suggest ovality.
-
Consult a Professional : If you are unsure of your observations or would prefer a professional opinion, it is always advisable to take your vehicle to a qualified mechanic. These professionals have the experience and tools necessary to accurately assess the condition of your brake discs.
Actions to Take
If the brake discs are found to be oval, it is essential to replace them as soon as possible to ensure the safety of the vehicle. It is also advisable to replace the brake pads at the same time to ensure efficient and safe braking. Ignoring this problem can lead to a deterioration in braking performance and increase the risk of accidents.
Brake disc ovalization is a serious problem that should not be ignored. Recognizing the signs and taking prompt action is essential to maintaining high standards of safety and vehicle performance. Performing regular maintenance checks and paying attention to the signals your vehicle may be giving you while driving can make the difference in preventing more serious damage to the components of the braking system.
Brake Disc Ovalization Prevention
While replacing damaged discs is a quick fix, it is equally important to adopt good driving and maintenance practices to prevent the problem from recurring:
-
Avoid Hard and Prolonged Braking : Overheating from heavy brake use is a major cause of ovalization. Trying to ride smoother and anticipating stops can significantly reduce stress on the discs.
-
Use Quality Materials : When replacing rotors or pads, opt for high-quality materials. Lower-quality components may not only wear out faster but also contribute to issues like ovalization.
-
Periodic Checkup : Even if you don't notice any obvious symptoms, a periodic checkup of your brake discs by a professional can help identify and fix problems before they get worse.
-
Beware of Heavy Loads : If your vehicle is frequently used for hauling heavy loads or towing, make sure your braking system is adequate for the job. Vehicles with excessive loads are more susceptible to braking problems due to the added stress on the rotors.
When to Contact a Professional
If you are unsure about the condition of your brake discs or prefer a professional approach, do not hesitate to consult a mechanic. An experienced technician can provide an accurate assessment, recommend the best course of action, and ensure the work is done correctly. Remember that road safety begins with proper maintenance of your vehicle.
Brake disc ovalization is a problem that requires immediate attention to ensure safe driving. By recognizing the warning signs and taking preventative measures, you can keep your vehicle's braking system in tip-top condition and reduce the risk of accidents. Remember, road safety is a shared responsibility, and taking care of your vehicle is the first step toward safer driving for everyone.
