Here are a few signs that it may be time to replace your rotors:
1. Pulsation or Vibration when Braking: If you feel a pulsation or vibration through the brake pedal when you brake, it can indicate uneven rotor wear or warping.
2. Squealing or Grinding Noises: Squealing or grinding sounds while braking can be a sign that your brake pads have worn down and are making contact with the rotors. However, it's worth noting that new brake pads can also produce some noise during the bedding-in process, which usually goes away after a few hundred miles.
3. Visible Wear or Heat Spots: Inspect your rotors for visual signs of wear, such as deep grooves or heat spots (bluish or discolored areas). Excessive wear or heat spots can compromise the braking performance and safety.
4. Low Brake Fluid Level: If your brake fluid level is low, it could be an indication of brake pad wear or leakage. Low brake fluid can lead to premature wear of brake components, including the rotors.
5. Warning Light Indicators: Some RAV4 models have a brake warning light that illuminates on the dashboard if there's an issue with the brake system, including worn brake pads or rotors.
If you notice any of these signs, it's best to have your brakes inspected by a qualified mechanic to determine if your rotors need replacement. Regular maintenance and timely replacement of brake components will help ensure safe and reliable braking performance for your RAV4.
