Why Do My Brakes Squeak?

Brake PedalWhile you’re soaring down the roads of Dartmouth, New Bedford, and Fall River, all you should hear is the smooth sound of a capable vehicle that’s effortlessly making its way over the asphalt.

However, when you start noticing a screeching noise coming from the brakes, it’s essential to get your car back into top-performing shape by determining the cause.

So, if you’ve found yourself wondering, “why do my brakes squeak?” the service professionals at Dartmouth Nissan are here to help with this handy guide on what might be causing that squealing sound. Let’s take a look!

1)  Rusty Rotors

Brake DiscOver time, your brake rotors build up rust from everyday humidity and moisture, especially if you live in an intensely humid or wet climate. As a result of that rust, you’ll likely hear squeaking or squealing when you apply pressure to the brake pedal.

What to Do:

Since excess rust on your brake rotors can prevent your brakes from working properly, you’ll want to visit a trusted service professional for routine brake care. That way, you’ll keep your brakes performing at their best and get rid of that squeak.

2)  Worn Brake Pads

As the most common cause of brake squeaks, it’s essential to have worn down brake pads replaced every 30,000 to 65,000 miles or so.

Without regular brake pad replacements, your brake pads will erode and expose the wear indicator, which is designed to let you know that you need brake service. At that point, you’ll hear a squealing sound every time you press on the brake pedal.

What to Do:

Brake pad indictors grab your attention by producing a squeak when you engage the braking system. It’s important to heed the warning of your brake indictors and visit your local service center for a brake pad replacement. By doing so, you’ll keep your brakes healthy and put a stop to the squeak, all with one service appointment.

3)  Rotor Debris

What to Do:

The best way to address this issue is to consult a knowledgeable car mechanic and have them take a look at your braking system. They’ll be able to determine if the squeak is a result of a rock or pebble scraping against your brakes or if it’s another problem entirely.

4)  Loose or Dirty Parts

Your braking system is comprised of a collection of different parts that work together to bring your vehicle to a stop. However, if one of those items comes loose, it can lead to a squeaking or vibrating noise while you’re driving or braking.

What to Do:

If a loose or dirty part is the source of your brake squeak, you’re in luck! This is actually a very simple issue for your service professional to fix. By adjusting, cleaning, or lubricating the part, your mechanic can repair the squeak, so you can sail down the road with peace of mind.

5)  Weather Conditions

Wheel SplashAfter a night in rainy, snowy, or humid conditions, your braking system builds up condensation, which leads to a temporary squeak when you first leave your driveway. For the most part, this noise disappears as your rotors dry off.

What to Do:

Keep an ear out for squeaking during the rest of your journey. If it stops, you’re in the clear. All you have to do to prevent the noise in the future is store your vehicle in a dry, enclosed parking garage. If it continues, you may want to schedule an appointment at your service facility for a brake checkup.
