Brake pads are a key component in your braking system as they generate friction that slows and stops your wheels. These pads gradually wear down or become damaged, and they’ll need to be replaced – which can be done easily at your trusted Toyota dealer. Here are some tips on when your pads should be replaced to ensure your braking system always works effectively.
What Are Pads?
The pads fit into the brake calipers, and a caliper is attached above each wheel rotor. When you hit the brakes, brake fluid generates hydraulic pressure that forces the calipers to close on the moving rotors. The pads fit inside the calipers and generate friction against the smooth rotors that bring the wheels to a stop.
New pads have a 1/2″ thick material covering, which slowly wears down each time you apply the brakes. When the material covering degrades to 1/4″ thick, the pad needs replacement.
How Often Do Pads Need Replacement?
On average, pads need to be replaced every 40,000 to 70,000 miles. The approximate time for replacement for your Toyota model is listed in your car manual. The replacement time can vary depending on several factors, including driving conditions and your driving style. If you frequently ride your brake, for example, the pads will wear out faster.
Signs You Need Replacement Pads
You’ll always receive warnings that your pads are wearing out – these are a few signs that they need to be changed.
Screeching Noises
A high-pitched screeching when you hit the brakes is an obvious sign that the pads need replacement. As we’ve seen, your pads need to be replaced when their material covering is reduced to 1/4″ thickness. When this happens, a metal spike inside the pads will become visible. The spike will scratch against the rotors as a warning that the pads need to be changed.
Grinding Noises
A harsh grinding noise from the brakes can mean that a stone or another object is trapped in the brake caliper. This sound could also mean that your pads have worn down completely. Once the material covering has gone, the metal of the brake calipers will be in direct contact with the wheel rotors when you brake. The calipers will continue to gouge the surface of the rotors until the pads are replaced.
Warning Light Illuminates
When the pads are wearing down and need replacement, sensors connected to the pads will send a warning to your car’s computer. The computer will identify the message, and the pad warning light on the dash will illuminate. The warning light will usually illuminate before you experience any strange sounds from the pads.
