Stop the Squeak for Car Brakes

Squeaky brakes are a common issue faced by car owners. This high-pitched, annoying sound can be quite distracting, but it also serves as an indicator that something is wrong with your braking system. In this article, we will discuss the reasons behind squeaky brakes and what you can do to resolve the issue.

Worn brake pads

The primary cause of squeaky brakes is worn brake pads. Brake pads are the replaceable friction pads that press against a vehicle’s rotor, creating friction that slows the vehicle down. When brake pads become worn, they can make a squealing noise, which is an indicator that it’s time to replace them.

Moisture

Another reason why brakes may squeak is due to moisture. Moisture can get into the braking system and cause a thin layer of rust to build up on the rotors. This rust buildup can cause a grinding or squealing sound when you apply your brakes, but it can usually be remedied with normal driving.

Low brake fluid

In some cases, low brake fluid can also cause squeaking brakes. When the brake fluid is low, the pedals cannot depress the brake pads with the same amount of pressure, causing uneven wear on the pads. This uneven wear can cause grinding, squeaking, or squealing noises when you apply your brakes, and the vehicle may also rumble and vibrate.

Uneven brake pads

Uneven brake pads can also be the cause of squeaking brakes after new pads have been installed. If the brake fluid is low, it can cause uneven wear on the brake pads, which can lead to squeaking, squealing, and grinding noises when you apply the brakes.

Dirty brake fluid

Dirty brake fluid can also cause squeaky brakes. When the brake fluid is dirty, it cannot depress the brake pads as efficiently as it should, leading to uneven wear or damage to the brake pads. This can cause grinding, squeaking, or squealing noises when you apply your brakes.

What Can You Do About Squeaky Brakes?

If your brakes are squeaking, there are several methods you can try to resolve the issue. One of the simplest methods is to apply grease to the brake pads. If your brakes are new and still making a squeaking sound, lubricating the contact points may solve the issue.

Install shims

Another solution is to install a set of shims. Shims are thin pieces of metal or plastic that can be installed between the brake pads and rotors to reduce vibration and eliminate squeaking. If your brake pads are worn, you should replace them immediately. Neglecting worn brake pads can lead to further damage and increased repair expenses.

Not to use WD40

You should not use WD40 on your brakes to stop squeaking. The solvent may only leave a slight oily film behind and will not resolve the underlying issue. If your brakes are worn, using WD40 will only mask the problem and put you at risk while driving.

In conclusion, squeaky brakes are a common issue that can be caused by several factors, including worn brake pads, moisture buildup, low brake fluid, and uneven brake pads. To resolve the issue, you can try applying grease to the brake pads, installing shims, or replacing the brake pads and rotors. It’s important to address squeaky brakes promptly to avoid further damage and increased repair expenses.
