The Science Behind Brake Squeaks
Brakes are one of the most critical parts of any vehicle. They help to decelerate or stop the vehicle when necessary, so it’s essential to make sure that they are functioning correctly. However, it’s not uncommon to hear a strange squeaking sound when you first start driving.
But why does this happen? Let’s delve deeper and explore the science behind brake squeaks.
Explanation Of How Brakes Work
Before we dive into the intricacies of brake squeaks, let’s briefly go over how brakes work:
- When you press down on the brake pedal, it activates a piston in the car’s brake calipers.
- This piston, in turn, depresses the brake pad against the rotor, creating friction that slows down the wheel.
- The brake pad is usually made of a composite material designed to withstand the heat and stress generated by friction with the rotor.
Why Brakes Make Noise
Now that we’ve covered the basics, let’s address why brakes make noise:
- Brake noise is essentially a result of the vibration created by the brake pad rubbing against the rotor.
- When this happens, it causes the brake caliper, lug nuts, and other parts of the braking system to vibrate, thus creating a shrill or grinding noise.
Common Causes Of Brake Squeaks
Here are some of the most likely reasons why your brakes are squeaking:
- Worn-out brake pads: When brake pads are past their prime, they tend to produce a high-pitched, metallic squealing sound every time you apply the brakes.
- Rusty brake rotors: When rotors start to rust, the brake pad only scrapes off the surface rust layer, creating a rhythmic squealing noise.
- Unlubricated calipers: Calipers get sticky when they’re not lubricated correctly. This causes them to move around when you brake, creating an annoying noise.
- Low-quality pads: Cheap brake pads can cause brake squeaking because they lack the proper composites to deal with the heat and pressure generated by braking.
- Glazed rotors: Overheated brake pads can sometimes create the heat and pressure necessary to turn the brake rotor’s surface into a glossy finish. When the brake pad rubs against the glazed rotor, it produces a high-pitched squeak noise.
While brake squeaks are generally not a cause for alarm, it’s best to err on the side of caution and take your vehicle to a professional mechanic for inspection. Don’t wait until it’s too late – regular maintenance and check-ups will help keep your brakes functioning optimally and keep you and your passengers safe.
Diagnosing Brake Squeaks
Recognizing Different Types Of Brake Noises
When driving, if your brakes squeak or make any noise, it’s typically a warning sign that something is not right. It is essential to know the different types of brake noises to diagnose the issue. Here are some common brake noises to be aware of:
- Squealing: It commonly occurs because of the vibration in the brake pads or when the brake pads are wearing out.
- Grinding: This noise indicates that your brake pads are worn out completely and that now the metal of the brake calipers is grinding against the rotors.
- Hissing: It is often a sign of a brake fluid leak or air leaking from the brake hose.
- Clicking: When the brake pads move back and forth and make a ticking or clicking sound, it suggests a problem with your brake hardware.
Determining The Cause Of The Noise
