1. High-Pitched Squealing or Squeaking
Most brake pads have built-in wear indicators—small metal tabs that contact the brake rotor when pads wear thin, producing a squealing noise. If you hear this regularly, schedule a brake pad replacement soon.
2. Harsh Grinding Sounds
A metallic grinding sound indicates your brake pads have worn down completely to the metal backing plate. This causes severe damage to your brake rotors and reduces stopping power. Pull over safely and seek service immediately.
3. Vibrating or Shaking Steering Wheel
If your steering wheel vibrates when you apply the brakes, your brake rotors may be warped or have uneven surface wear due to extreme heat. Rotors must be resurfaced or replaced to restore smooth stopping.
4. Spongy or Soft Brake Pedal
If the pedal feels soft or sinks to the floor before engaging, you may have air in your brake lines or a brake fluid leak. This is a critical safety issue that requires immediate professional inspection.
