Why Are My Brakes Squeaking?

Brake Repair

Have you recently heard a loud whining coming from your car, particularly when you’re applying brake pressure? If you’ve noticed odd noises while pressing the brake pedal, it could mean that there’s an issue with your brakes. It’s important to know the warning signs of any potential problem your car could face out on the roads of Irving, Grand Prairie, Grapevine, and Dallas, TX.

Considering just how important brakes are to the safe operation of your car, it’s a good idea to understand what can cause squeaky brakes and if there’s any reason to be concerned. Luckily, the automotive professionals at Principle Volkswagen wrote this squeaking brake guide to help you discern why your brakes might be making irregular and unpleasant sounds.

Common Causes

Worn Down Brake Pad Brake Pad Wear

Disc brakes have a few essential components: a caliper, pads, and a rotor. When you press the brake pedal, a caliper forces the pads into a rotor to create friction, which quickly accumulates to slow down your car. One of the most common causes for squeaking brakes are worn-out brake pads. They’re designed to wear away a little bit each time you stop until they eventually need to be swapped out.

Auto parts manufacturers understand how crucial brakes are to safety, so the reason you’re probably hearing a whining noise is actually a result of the brake pad telling you that they require replacement. Most brake pads are equipped with wear indicators that emit a loud, high-pitched squeak when the pad has worn down by a certain percentage.

When you hear this sound, you’ll want to make a visit to have your brakes inspected and possibly replaced.

Rusty Rotors

Like other components on your car, brake rotors are subjected to wet conditions, whether you’re actively driving or not. If there was a substantial amount of rain the night before or it’s overly humid, your rotors can accrue rust rather quickly. When the pads press against rust-covered rotors, they’ll release an uncomfortable whine.

Don’t worry, this is a simple issue with an even easier fix—although you’ll have to persist through that squeaking noise for about another half hour or so. All you’re required to do is drive at a low speed while applying light brake pressure. The pads will actually rub the rust from your rotors and subsequently eliminate any uninvited sounds.

How Old is Your Brake Fluid?

Brake FluidBrake fluid is an integral element to the braking system because it’s a hydraulic fluid as well as an internal lubricant. When you have old brake fluid circulating, it can cause some problems. As a hydraulic fluid, it maintains pressure throughout the system so that the calipers can physically push the brake pads against the rotors and stop your vehicle.

Over time, brake fluid can become less effective as it thickens and is unable to travel as easily. Since brake fluid is highly corrosive, it can bore through the metal components around your brakes, sometimes resulting in a squealing sound.
