Why Are My Brakes Squeaking?

Replacing Brakes

When it comes to staying safe out on those Mobile, Prichard, Saraland, and Daphne roads, high-functioning brakes are an absolute necessity. So, naturally, you might feel a bit nervous if you hear them making noise.

Why exactly do brakes squeak, and what can you do to stop it? In this article by the Nissan of Mobile team, we’re going to outline everything for you.

What Does It Mean When Brakes Squeak?

There’s quite a few reasons why your brakes could be squeaking, and it’ll vary depending on whether or not you have disc brakes or drum brakes. However, these are the four most common causes that we typically encounter at our service center.

1. Your brakes are rusty.

The idea of brake rust might seem like a big deal. Honestly, though, this is the most common occurrence on the list.

Just from sitting overnight, perhaps in the rain, or with a nice bit of morning dew, a thin layer of rust can easily form on your brakes. This will then cause them to squeal a bit as you first start driving.

Eventually, the natural friction of your ride will burn off the rust, so to speak. However, if the car has been sitting for a long time (say, weeks), it might be harder to get rid of.

2. The brake pads are thin.

Brake pads play a very important role in your brake system. They apply the pressure and friction to your rotors needed to slow the vehicle to a stop.

Your brake pads come with a wear indicator that will let you know exactly when they need to be changed. As they start to grow thin, the indicator will sound with an unmistakable squeak. As soon as you identify this, you’ll want to have your brake pads changed.

3. There’s too much metal in your brake pads.


These days, brake pads are made with all sorts of materials. More often than not, they come with organic materials. For instance, many are made with rubber, resins, and fibers.

However, some inexpensive pads are still made with high metal content. Metal is known to make a scraping or squealing sound if rubbed on, so that may be what you’re hearing.

Over time, some of that metal content should wear down. Still, you may be hearing a squeak for a while.

4. Lubrication is needed.

Does your vehicle have drum brakes? Then they’re definitely going to need a bit of lubrication from time to time.

Lubrication is what helps to dissipate some of the more harmful friction you might encounter when braking. If they go dry, they’re going to rub and eventually start to squeal quite loudly.
