If you hear a squeaking or squealing noise from your brakes, it could signify that your brake pads are worn. However, there are several other potential causes of this noise, including temporary factors like rust on the rotors or new pads that haven’t adjusted to the rotors yet. If the noise goes away after just a few brake applications, it’s probably not a problem. But if it persists or gets worse, it’s time to have your brakes checked by a mechanic.
If you don’t know what’s causing your brakes to squeal, you’re in the right place as your trusted mechanic in Hoover, AL, shares with you some of the possible reasons your brakes are squealing:
Worn-Out or Thinning Brake Pads
Worn-out or thinning brake pads are one of the most common reasons your brakes may start squealing. When your brake pads wear down, they become thinner and no longer provide as much cushioning between the caliper and rotor. This can cause a metal-on-metal contact, which results in that irritating squealing sound.
If your brake pads are worn-out or thinning, it’s crucial to replace them as soon as possible. Not only will this stop the squealing, but it will also help to improve your braking performance and prevent damage to your calipers and rotors.
Loose or Worn-Out Brake Calipers
Another possible reason for squealing brakes is loose or worn-out brake calipers. If your calipers are loose, they may not be properly seated against the rotor, which can cause a squealing sound. Additionally, worn-out calipers may start to squeal as they no longer provide a tight seal against the rotor.
If your calipers are loose or worn out, they must be repaired or replaced as soon as possible. This will help to improve your braking performance and prevent further damage to your brakes.
Dirty or Glazed Brake Rotors
Dirty or glazed brake rotors can also cause your brakes to squeal. When your rotors become dirty or glazed, they can become less effective at stopping your vehicle. Additionally, the brake pads may not be able to grip the rotor, which can also cause squealing.
If your rotors are dirty or glazed, it’s essential to clean them or have them resurfaced as soon as possible. This will help to improve your braking performance and prevent further damage to your brakes.
Lack of Lubrication on the Drum Brakes
One of the most common reasons for squealing brakes is a lack of lubrication on the drums. When the drums are dry, they can squeak when the brakes are applied. This is usually an easy fix – lubricate the drums with a brake lubricant, and the squealing should stop.
Metallic Brake Pads
Brake pads are made of various materials, but the most common type is metallic. These pads are very effective at stopping your car but can also be noisy. When the pads wear down, they can start to squeal or screech.
One way to reduce the noise from your brakes is to switch to a non-metallic pad. These pads are made of ceramic or organic materials, which are much quieter than metal. However, they can be more expensive and may not last as long as metallic pads.
Conclusion
If you are hearing a squealing noise coming from your brakes, it is vital to take action and have them checked out. There are a few potential reasons for this noise, some of which we have shared here, and it is best to have a professional diagnose the issue and provide you with the necessary brake service.
