Signs of worn-out brake pads

1. Squealing or Squeaking Noises

• High-Pitched Sound: A high-pitched squealing or squeaking noise when applying the brakes is often a sign of worn brake pads. This noise is typically caused by a built-in wear indicator that alerts the driver when the pads are nearing the end of their useful life.
• Persistent Noise: If the noise persists even when the brakes are not applied, it could indicate that the pads are completely worn down and metal-to-metal contact is occurring.

2. Grinding Sound

• Metallic Grinding: A grinding or growling noise when braking is a more serious sign. This typically indicates that the brake pads are completely worn out, and the metal backing plate is coming into contact with the rotor. This can cause significant damage to the rotors and reduce braking efficiency.

3. Reduced Brake Performance

• Longer Stopping Distances: If you notice that your vehicle is taking longer to stop than usual, it could be a sign that the brake pads are worn and not providing adequate friction.
• Increased Pedal Pressure: Needing to apply more pressure to the brake pedal to achieve the same stopping power is another indicator of worn brake pads.

4. Vibration or Pulsation

• Vibrating Pedal: A vibrating or pulsating brake pedal, especially under normal braking conditions, can indicate unevenly worn brake pads or warped rotors.
• Steering Wheel Vibration: In some cases, the vibration may be felt in the steering wheel, suggesting issues with the front brakes.

5. Brake Pad Thickness

• Visual Inspection: You can often check the thickness of the brake pads through the wheels. If the pad material is less than 1/4 inch (about 6.35 mm) thick, it’s time for a replacement.
• Wear Indicators: Some brake pads come with wear indicators that make it easier to check pad thickness. If the indicator shows the pads are worn, replacement is necessary.

6. Indicator Lights

• Dashboard Warning Light: Many modern vehicles have electronic wear sensors that trigger a dashboard warning light when the brake pads need to be replaced. Pay attention to any brake warning lights on your dashboard.
