Understanding squeaky brakes

Hearing a squeak every time you hit the brakes can be annoying and sometimes worrying. Squeaky brakes can happen for several reasons, and it’s important to know what’s causing the noise and how to fix it. At GenTech Automotive, we want to help you understand why your brakes might be squeaking and what you can do about it.

Common causes of squeaky brakes

Worn brake pads

One of the most common reasons for squeaky brakes is worn brake pads. Brake pads have a built-in wear indicator that makes a squeaking noise when it’s time to replace them. If you hear a high-pitched squeak, it might be a sign that your brake pads are getting thin and need to be changed.

Dust and dirt

Sometimes, dirt and dust can get caught between the brake pads and the rotors, causing a squeaking noise. This is more common if you drive on gravel roads or in dusty conditions. A good cleaning can often solve this problem.

Moisture

If you’ve noticed that your brakes only squeak in the morning or after it rains, it might be due to moisture. Water can cause a thin layer of rust to form on the brake rotors, which can make the brakes squeak until the rust is worn off.

Glazed brake pads or rotors

If your brake pads or rotors get too hot, they can become glazed, creating a shiny, hard surface. This can cause squeaking because the pads can’t grip the rotors properly. Glazing often happens from excessive braking, like driving down a long hill or frequent stop-and-go driving.

Loose parts

Sometimes, the noise can come from loose parts in the brake system. If any components are not tightened properly, they can cause vibrations that lead to squeaking.

Low-quality brake pads

Using cheap or low-quality brake pads can also cause squeaking. These pads might not be made from the best materials, leading to more noise and less effective braking.

How to fix squeaky brakes

The first step to fixing squeaky brakes is to check the brake pads. If they are worn down, replace them. It’s a good idea to use high-quality brake pads to guarantee better performance and less noise.

If dust and dirt are causing the squeak, cleaning the brake components can help. You can use a brake cleaner spray to remove any dirt and debris from the pads and rotors.

Then go ahead and apply a special brake lubricant to the back of the brake pads and other moving parts. It can reduce squeaking. Be careful not to get any lubricant on the pad surface or the rotor.

If the rotors are glazed, they might need to be resurfaced or replaced. Resurfacing removes the top layer of the rotor, eliminating the glazed surface. If the rotors are too thin or badly damaged, replacing them is the best option.

Then make sure all the parts in the brake system are properly tightened. This includes the calipers, mounting brackets, and other components. Tightening loose parts can reduce vibrations and eliminate noise.

Also, investing in high-quality brake pads and rotors can make a big difference. These parts are designed to work better and last longer, reducing the chance of squeaking.

How to prevent squeaky brakes

Regular maintenance is key to preventing squeaky brakes. Here are some tips to keep your brakes in good condition:

Have your brakes inspected regularly by a professional. This can help catch any issues early before they become bigger problems. Come in for a logbook service.

Make sure your brake fluid is topped up and in good condition. Old or low brake fluid can affect brake performance and lead to noise.

Try to avoid hard braking whenever possible. Gradual braking is easier on your brake pads and rotors and helps them last longer.

Regularly clean your wheels and brake components to remove dust and dirt. This can prevent debris from causing squeaking.

Always use high-quality brake pads and rotors. They might cost a bit more, but they perform better and reduce the chance of noise.
