It may not always be obvious when there's a problem with your vehicle, but if there's an issue with your brakes, they'll start to squeal to let you know. Your brakes' health and integrity are a vital component to on-the-road safety for you and your passengers. Unusual brake sounds shouldn't be ignored. Below are three reasons why your brakes have begun to squeal.
The brake pads are worn.
Brake pads aren't designed to last forever; as you drive, they'll eventually wear thin. If your brakes are worn down to the metal, they'll begin to produce a squealing sound. The brake pads aren't easy for the everyday driver to check. If you're starting to hear a squeal from your brakes, it's vital to have them inspected.
The brake fluid needs to be changed.
The brake pads are not the only aspect that can wear; the brake fluid can as well. The brake fluid is a hydraulic fluid that aids the brakes' movement to slow down or stop your vehicle. It also works as a lubricant for the brake system with anti-corrosion properties. Old brake fluid can become clumpy and sludge-like. This can cause it to lose its lubricating properties, viscosity, and, eventually, its effectiveness. If the brake fluid needs to be changed, you may notice a distinctive squeal from your brakes.
The brake rotor is rusted.
That high-pitched squeal may be coming from your brake rotors. Rain and humid weather can make the brake rotors more susceptible to rust. Brake pads that are pressed against rusted rotors will give a loud squeal. While it's possible to shave the rust off by light presses on the brake pad, rust can be damaging to your vehicle. If you suspect that your rotors have rusted, bring your vehicle in to have them checked.
