Brake squeal at low speeds, also known as squeaky brakes, can be attributed to a variety of factors such as worn brake pads, debris, and high-performance brake materials.
Finding the right solution requires identifying the cause of the brake squeal.
While it’s normal for brakes to emit some noise, persistent squeaking or squealing could indicate that something is amiss.
Addressing any brake squeal issues immediately is paramount for the safety of you and your passengers.
Here are some steps you can take to reduce brake squeal:
Regularly clean and lubricate brake components.
Adjust braking components as needed.
Park your car indoors to protect your brakes from moisture and rust.
Drive your car regularly to prevent brake components from seizing up.
Taking these preventive measures can help protect your brakes and reduce brake squeals, ensuring that your brakes squeak less frequently and your replacement brake pads last longer.
Common Causes of Brake Squeal at Low Speeds
Understanding the most common causes is vital for effectively addressing brake squeals at low speeds, which are worn brake pads, dust and debris, glazed rotors, and high-performance brake materials.
Identifying the cause behind your squeaky brakes allows you to take corrective steps, ensuring a quieter, smoother ride.
Worn Brake Pads
Thinning or worn brake pads are among the most common causes of squealing brakes.
As the brake pad wears down, it may emit a high-pitched screeching or squealing noise when the brake pedal is pressed.
A wear indicator, a small piece of soft metal, is present in the brake pad.
This indicator is designed to make a noise when your brake pads are too low. It is a safety feature designed so that you replace your brake pads before they cease to function correctly.
Promptly addressing worn brake pads is crucial, as they can potentially damage the rotors, leading to expensive repairs.
Using manufacturer-recommended quality brake pads is key to preventing such issues.
High-performance brake pad material, such as semi-metallic brake pads, may occasionally cause brake squeal at lower speeds and with mild braking when still new, owing to the components found in the brake parts.

Regular inspection of your brake pads for signs of wear can help prevent brake squeals caused by worn pads.
Dust and Debris
Accumulation of dust, dirt, or debris between the brake pads and rotors can cause squealing noises.
Dust and debris can contribute to brake squeal by becoming lodged in the brake pads and causing them to vibrate.
This friction can result in a high-pitched squeal, which can be annoying and potentially harmful to your brake components.
By keeping your brake pads clean and free of debris, you can help ensure a smoother and quieter braking experience.
Glazed rotors are another potential cause of brake squeal at low speeds.
Hard braking at high speeds can cause rotors to become glazed, forming a smooth surface that does not allow the brake pads to properly grip the rotor.
This can lead to noises and other braking issues, such as warped rotors.
Using the best quality brake pads is crucial in preventing glazed rotors and brake squeal.
Here are some recommended braking tips to help prevent these issues:
Avoid hard and fast braking
Avoid riding the brakes downhill
Properly maintain your brake components, including cleaning or resurfacing the rotors
Inspect the calipers and hydraulic system for any mechanical issues or failure
By following these tips, you can help prevent glazed rotors and a potential source of brake squeal.
High-Performance Brake Materials
Some high-performance brake materials, such as metallic brake pads, can cause occasional squealing noises.
This is because these materials have a higher friction coefficient and increased heat dissipation, which can result in a squealing noise during braking.
However, it’s important to note that this issue is generally temporary and should subside as the brake pads wear in.
Ensuring accurate installation and applying a brake lubricant when necessary is key to minimizing brake squeal caused by high-performance brake materials.
Additionally, using a higher-quality brake pad can help reduce the chances of squealing noises from high-performance materials.
New Brakes and Low-Speed Brake Squeal
Newly installed brakes may squeal due to inefficient bedding in or improper installation.
Bedding in is a process where the brake pads and rotors become accustomed to each other, and it may take a few days for the squealing noise to subside.
However, if the noise persists, it could be due to a technician not adequately tightening a component of the brake system, resulting in increased vibration and noise.
Brake pad retaining clips are an overlooked part of brake jobs. These clips are often reused instead of replaced because it is easier to do so.
These old clips that hold your brake pads are often worn and allow the brake pad to move within the caliper.
This can be a source of brake noise as well as insufficient brake wear.
Should you experience brake squeals with your new brakes, getting them inspected by a qualified mechanic for diagnosis and resolution is pivotal.
An experienced technician will be able to make any necessary adjustments to your brake components, ensuring a smooth and quiet braking experience.
How to Fix Brake Squeal at Low Speeds
Several methods, including cleaning your brakes, lubricating brake components, and adjusting braking components, can be used to address low-speed brake squeal.
Employing these techniques effectively eliminates the noise, allowing for a smoother, quieter ride.
Cleaning Your Brakes
Cleaning your brakes is an essential step in eliminating squealing noises.
You can clean your brakes using a brake cleaner or a degreaser, and it’s recommended to clean them every six months or if you observe any accumulation of dirt or debris.
To clean your brakes, follow these steps:
Start by loosening the lug screws/nuts with a wrench or socket and removing the wheel.
Use compressed air to eliminate dust and debris from the brake caliper.
Scrub away dirt and dust from the caliper housing with a wire brush.
Finally, apply a generous amount of brake cleaner to the brake rotors, holding the can at least 6 inches away from the rotors.
Lubricating Brake Components
Lubricating brake components is another essential step to reduce brake noises.
Applying brake grease or lubricant to appropriate parts can help ensure the smooth movement of the seals, prevent corrosion and sticking of the parts, and reduce screeching and squealing noises.
It’s recommended to lubricate your brake components every six months or when any signs of wear or corrosion are observed.
To lubricate your brake components, use a high-temperature brake lubricant specifically designed for this purpose to prevent seal swelling and failure.
Apply the lubricant to the relevant parts of the brake assembly, including the caliper pins, the back of the brake pads, and contact points between the brake pads and the caliper.
Ensuring proper lubrication of your brake components can significantly help in reducing brake squeal at low speeds.
Remember you should never get lubricant on the face of the rotor or the brake pad. In case you do, you must remove it immediately with brake cleaner otherwise you will have no brakes!
Adjusting Braking Components
Ensuring that your brake components are correctly adjusted can provide a range of benefits, including:
Consistent and efficient braking
Easier vehicle maneuverability
Enhanced braking performance
To adjust your braking components, follow these steps:
Inspect the brakes to check for any signs of wear or corrosion.
