| Shaking when braking | Warped rotors, uneven brake pad wear, diminished braking effectiveness |
Grinding Noises
If you hear a grinding noise when braking, it is a clear indication that your brake pads have worn down completely and the metal backing plate is now rubbing against the brake rotor. This can cause significant damage to both the brake pads and the rotors. In this case, it is necessary to replace both the brake pads and the rotors to maintain a safe and effective braking system.
The grinding noise occurs because the brake pads, which have a metal backing plate, have worn down beyond their usable thickness. When the backing plate comes into contact with the rotor, it creates a harsh grinding sound. Ignoring this noise can lead to further damage, including warping of the rotor surface.
To resolve this issue, it is essential to replace both the brake pads and the rotors. This ensures that the new brake pads will have a smooth and flat rotor surface to adhere to, allowing for proper braking performance. If only the brake pads are replaced without addressing the worn rotors, the new pads will not provide optimal contact, leading to decreased braking efficiency and potential safety concerns.
Metal on Metal: The Dangers
When the brake pads have worn down to the point of metal on metal contact, it creates a dangerous situation. The metal backing plate rubbing against the rotor can cause excessive heat, leading to brake fade and reduced stopping power. Additionally, the friction generated can cause significant damage to the rotor, resulting in the need for more extensive repairs.
Ignoring grinding noises when braking is not only unsafe but can also result in costly repairs. It is crucial to have your brake pads and rotors inspected and replaced as necessary to ensure the ongoing safety and performance of your vehicle’s braking system.

Longer Stopping Distances: A Sign of Worn Brake Pads
If you’ve noticed that your vehicle takes longer to come to a complete stop when braking, it could be an indication that your brake pads are worn down. When brake pads become thin or low, they are not able to provide sufficient friction to the brake rotor, resulting in longer stopping distances. This can be dangerous, especially in emergency situations where quick and responsive braking is essential.
One of the reasons for longer stopping distances is the decreased ability of the brake pads to create the necessary friction. As the brake pads wear down, there is less material available to make contact with the brake rotor, which reduces the overall stopping power. Additionally, low brake pads can put increased stress on the brake caliper, as it needs to apply more force to generate adequate braking performance.
Causes of Longer Stopping Distances:
- Low brake pad thickness
- Reduced friction between brake pad and rotor
- Inadequate braking force from the brake caliper
It is crucial to address longer stopping distances promptly to ensure your safety and the safety of others on the road. By replacing the worn brake pads and addressing any underlying issues with the brake caliper or rotor, you can restore the optimal braking performance of your vehicle and reduce the risk of accidents.
In some cases, longer stopping distances may also be caused by other factors, such as worn brake rotors. If the brake rotor surface is damaged or uneven, it can reduce the contact area with the brake pads, leading to reduced braking efficiency. Therefore, it is important to have a comprehensive inspection of your braking system to identify any potential issues and address them accordingly.
