Why Are My New Disc Brakes Squeaking?

If your back brakes have started squeaking just four months after replacement, you might be wondering what the cause is. This guide will explore why this phenomenon occurs and what steps you can take to address the issue.

Common Causes of Squeaking Disc Brakes

When you replaced your rotors and brakes not too long ago and you're now experiencing squeaking noises, it could be due to several reasons. Here are some common causes you should consider:

Excessive Driving with Parking Brakes Applied

One potential cause is if you've been driving with the parking brakes partially applied. This can cause the brake pads to wear down more quickly and result in squeaking noises. To rule out this possibility, check if the noise stops when you apply the parking brakes. If it does, it indicates that the brake pads have worn down faster than expected.

Dust and Particles Accumulating in Brake Components

Another possible cause is dust and particles that have accumulated in the brake components. These can cause noise, especially when the brakes are not regularly maintained. One easy way to address this issue is to give your brakes a thorough cleaning, especially if you wash your car regularly. Spray the brake components with a cleaning solution to remove any accumulated dust and debris. This can help reduce or eliminate the squeaking noises.

Improper Installation of Brake Pads

If the anti-squeal shims and/or adhesive were not used during the installation of the brake pads, it can also cause the brakes to squeak. These shims and adhesives are designed to reduce noise and ensure a smooth operation of the brake system. Check if these components were used during the installation process. If they were not, consider getting your brakes inspected by a professional mechanic who can install these components correctly.

Visible Signs of Wear and Tear

Inspect the rotor surface and the inside of the caliper for any signs of wear and tear. If you can see through the spokes of your wheels, take a look at the rotor surface for any grooves or roughness. Use your fingertip to feel the surface of the rotor for any irregularities. If you notice any, it could be a sign that the brake pads need to be replaced soon. However, if the surface appears to be in good condition, a thorough cleaning around the edges of the caliper might help.

Grinding Noise – Immediate Attention Needed

If the squeaking noise sounds more like a grinding sound, it is crucial to have your brakes inspected as soon as possible. This type of noise can indicate a more serious problem, such as wear on the rotors or brake pads, and missing or damaged pieces. Prompt attention can prevent further damage and save you money in the long run.

Conclusion

Disc brakes squeaking can be caused by a variety of factors. By checking if your parking brakes were applied excessively, ensuring that your brakes are clean from dust and particles, and verifying if the anti-squeal shims and adhesives were used during installation, you can identify the root cause of the noise. Always prioritize safety when it comes to your vehicle, and have any grinding or unusual noises checked out promptly.

Remember, regular maintenance and inspection of your brakes can prevent many issues and keep you and your passengers safe on the road.
