How Do You Know If Your Brake Discs Are Bad? 3

When it comes to automotive safety, there is no doubt that the brakes are a critical component. The brake discs or brake rotors are responsible for slowing or stopping the wheels from turning, and any problems with your brakes should be addressed immediately. Here are some warning signs to look out for, indicating that your Frontech Auto Parts brake discs may need attention.

Sub-Heading 1: Unusual Noises While Braking

One of the most common signs that your brake discs are bad is the presence of unusual noise when braking. That sound could be a high pitched or a grinding noise. Most cars have a brake wear indicator that squeals or makes a screeching noise when the pads are near their end. If you hear this noise, it may be time to schedule brake service. Incompatible brake pads, stuck calipers, and loose brake parts like bolts can also cause noise when braking.

Sub-Heading 2: Reduced Braking Performance

When you depress the brake pedal, your car should come to a smooth halt within a reasonable distance. However, if there is a reduction in braking performance or longer stopping distance than usual, then it could be a potential sign that there is something wrong with your brake system. Sometimes the brake pedal feels spongy or requires pumping to work, which can be an indicator that the brake fluid level is low or other hydraulic issues.

Sub-Heading 3: Vibration or Shaking While Braking

If you feel a vibration or shaking in the steering wheel or the brake pedal while braking, it's essential to have the problem looked at immediately. You may feel the vibration or shaking intermittently along with the symptoms discussed in sub-heading two, indicating the need for further investigation.

Sub-Heading 4: Scarring or Wear

Regularly inspecting your brake disc rotors for signs of wear and tear can help you avoid larger problems. The brake discs should generally be flat and smooth, but if you see any grooves, cracks, scores, or spotting, then replacement might be needed. These above issues affect the contact area with the brake pads resulting in reduced braking power and performance.

Sub-Heading 5: Brake Warning Light

If the brake warning light on your car's dashboard is illuminated, then it is a warning sign that there is an underlying issue with the brake system. It could be low brake fluid pressure, a hydraulic leak, or an Anti-lock Brake System (ABS) failure.


While following the vehicle manufacturer's suggested maintenance schedule will ensure your brake system is always functioning correctly, it is vital to be vigilant and stay alert for the above-discussed symptoms that could indicate that your Frontech auto parts brake discs need replacement. The faster you diagnose the problem, the quicker you can rectify it, and the easier it is on your wallet. We encourage anyone who suspects a problem with their brake discs, pads, or brake system to schedule an appointment with a qualified technician immediately.


Based on the information provided in this article, it is clear that there are several warning signs that may indicate that your brake discs are faulty. Such signs include unusual noises, vibrations, and inconsistent braking. It is vital to pay attention to these signs and take action immediately to ensure your safety and that of others on the road. Routine maintenance and inspection of your brake system can also help prevent brake disc problems. Remember, never take chances with your brakes; it is always better to be safe than sorry. If you notice any of these signs, make sure to take your vehicle to a trusted mechanic for a thorough inspection and repair. With these steps, you can maintain optimal brake performance, keeping you and your passengers secure while on the road.
