You know it's time to replace the pads in your disc brakes by looking for several key signs:
- Visual Thickness Check: Inspect the brake pads through the wheel spokes or by removing the wheel. If the friction material on the pad is less than about 1/4 inch (6.4 to 7 mm) thick, or if the pad material is worn down to 1 mm or less before the metal backing shows, it's time to replace them
- Squealing or Squeaking Noises: A high-pitched squeal when braking usually indicates the built-in wear indicator is contacting the rotor, signaling worn pads that need replacement soon
- Grinding or Metallic Noise: A deep grinding or growling sound means the pads are completely worn and the metal backing is scraping the rotor, which can cause serious damage. Immediate replacement is necessary
- Brake Performance Issues: If you notice longer stopping distances, vibration or pulsation when braking, or your vehicle pulling to one side, these can be signs of worn or uneven brake pads
- Brake Warning Light: Many modern vehicles have a dashboard brake pad indicator light that illuminates when pads are low
- Mileage Consideration: Brake pads generally last between 25,000 to 65,000 miles, depending on driving conditions and style. If you reach this mileage range without inspection, it's wise to check or replace them
In summary, regularly inspect your brake pads for thickness, listen for warning noises, watch for brake warning lights, and be alert to changes in braking performance. Replacing pads before they wear too thin prevents damage to rotors and maintains safe braking
