Signs of Wear and When to Replace Brake Pads and Rotors
Brake pads and rotors are crucial components of your vehicle’s braking system. Proper maintenance and timely replacement are essential for your safety on the road. Here are six signs of wear that indicate it’s time to replace your brake pads and rotors:
Squealing or Screeching Noises:
One of the most common signs of worn-out brake pads is a high-pitched squealing or screeching noise when you apply the brakes. This sound is usually caused by a metal wear indicator rubbing against the rotor. When you hear this noise, it’s time to replace your brake pads.
Vibrations and Pulsations:
If you feel a pulsating sensation or vibrations in the brake pedal or steering wheel when you brake, it may indicate that the brake rotors have become warped or unevenly worn. In such cases, both the brake pads and rotors might need replacement.
Reduced Brake Responsiveness:
If you notice that your vehicle takes longer to come to a complete stop or requires more pressure on the brake pedal, it could be a sign of worn-out brake pads. The reduced responsiveness indicates that the brake pads have worn down and need replacement.
Visible Wear Indicator:
Some brake pads have a built-in wear indicator that becomes visible when the pads have reached a certain level of wear. You can visually inspect the brake pads through the wheel spokes, and if the pad thickness is near or below the wear indicator, it’s time to replace them.
Thin Brake Pad Thickness:
Inspecting the brake pads directly can give you an idea of their remaining thickness. If the brake pads appear significantly thinner than when they were new, it’s time for a replacement. Generally, brake pads with less than 1/4 inch (6.35 mm) of pad material should be replaced.
Deep Grooves or Scores on the Rotors:
Inspect the brake rotors for deep grooves, scores, or cracks on the surface. Over time, the friction caused by the brake pads can wear down the rotors, compromising their effectiveness. If you notice any severe damage, it’s advisable to replace both the brake pads and rotors.
When to Replace:
The timing for brake pad and rotor replacement can vary depending on your driving habits, the quality of the parts used, and the conditions you drive in. As a general guideline, brake pads typically need replacement every 30,000 to 70,000 miles (48,000 to 112,000 kilometers), while rotors can last longer, often up to 70,000 miles or more. However, it’s essential to follow the manufacturer’s recommendations in your vehicle’s manual and have your brakes inspected regularly by a qualified mechanic.
