Why Do My Brakes Squeak?

Strange noises coming from your vehicle can be unsettling, but not all sounds warrant concern. If your brakes are squealing or squeaking, there are many possible causes, some of which require your attention.

If you’re wondering “why do my brakes squeak?” we’re here to help. Take a look at the major causes of brake noise and find out where to go for your brake service in Providence, Cranston and Pawtucket.

Rust on Your Rotors

When your car sits overnight, moisture from rain or morning dew collects on the rotors, creating a thin layer of rust. This is harmless, but the rust is scraped off as your brake pad moves along the rotor, creating a squeak.

There’s no way to fix these squeaks, other than storing your car in a climate-controlled garage, but at least it’s not a sign of brake problems.

Worn Brake Pads

Brakes are important for your vehicle’s safety, so many brake pads come with a built-in wear indicator strip. This strip is made of steel, so when the soft part of the pad is worn down, this metal scrapes along the rotor and creates a squealing sound. These are designed to hit the rotor before the brake pad is dangerously low, giving you time to schedule your brake replacement.

That said, the constant scrape of this metal strip along your rotor can cause damage to your rotor over time. If ignored, the metal-on-metal contact can affect the smooth surface of the rotor, which is expensive to replace.

Cheap Brake Pads

Brake pads can last tens of thousands of miles, so you’ll be listening to that squeaking sound until your pads are replaced. In addition, your brakes are vital to your vehicle’s safety, so it makes good sense to invest in high-quality brake pads that are more reliable.

Unlubricated Drum Brakes

While most vehicles have disc brakes, some vehicles use drum brakes for the rear. If you have squealing from the rear drum brakes, this could mean the shoe-to-backing contact points are rusted. When this happens, the rotation of the wheels causes a squealing sound, but a little bit of lubrication is all it takes to fix the problem.
