No matter the age or condition of your vehicle, brake noises are like nails on a chalkboard. Each time you come to a stop, and your brakes squeak or make another unusual noise, the sound can be alarming. More importantly than that, unusual brake noise can indicate a significant safety issue that could keep your car from stopping properly.
If you have a brake problem, you might hear grinding, clattering, rattling, or squeaking sounds. Here’s a breakdown of the most common causes of brake noises:
1. Worn or Thinning Brake Pads or Shoes
The most common cause of squealing brakes is worn brake pads or shoes. Brake pads and shoes are intentionally constructed with metal fabrication that emits a high-pitched sound once they reach their minimum thickness. If the sound of brake squeaking, squealing, or grinding continues, have a professional mechanic check your brakes as soon as possible.
2. Debris Between the Brake Pads and Rotors
The more you drive, the easier it is for dirt, dust, and debris to accumulate on the surfaces of your brake pads or rotors. If this is the issue, an auto repair shop can conduct a thorough cleaning or a sanding down of the surface material to address the issue.
3. Braking at High Speeds
If you want to drive fast, be aware that repeatedly braking at faster speeds can place wear and tear on your brakes. Continuously braking hard can generate excessive heat, which can cause a glaze to form on the surface of your brake pads and rotors, too.
4. Lack of Lubrication
Some vehicles have drum brakes that require lubrication at contact points between the drum and the shoes. Without proper lubrication, the shoes can begin to rub up against the backing plate, resulting in a squealing sound.
5. Moisture
Chances are, you’ve probably noticed an odd-sounding noise coming from your brakes first thing in the morning. Moisture can set in because of overnight humidity, which isn’t a cause for alarm. Conditions like snow, rain, and sleet can also cause brake noises. If this is the case, the sounds should start to disappear once you begin driving.
If you’ve noticed squeaking or grinding brakes, don’t put yourself or others at risk. When your brakes are making a racket, have an experienced auto repair shop check them out as soon as possible. Get your brakes diagnosed by a professional to keep your vehicle running as safely as possible.
