Squealing Brakes At Low Speed: Why Does It Happen?

When you hear your brakes squeaking at low speed, it can be both annoying and worrying. Squealing brakes often indicate a problem that needs attention. Here are some common reasons why brakes squeak at low speed and what you can do about it:

High-Frequency Vibration

One main cause of squealing brakes at low speed is high-frequency vibration. This happens when the brake pads rub against the rotating disc, creating that high-pitched noise. The caliper holds the pads tightly against the disc, causing unavoidable vibrations. This noise can be influenced by road conditions and weather, especially in muddy or dusty environments.

 Brake Pad Condition

The condition of your brake pads plays a significant role in whether your brakes squeak when stopping slow. Worn-out or damaged brake pads are more likely to make noise. Sometimes, a small stone or dirt can get stuck in the brakes, causing temporary squealing. A quick pressure wash can often fix this issue by removing the debris.

Brake Pad Material

Different materials used in brake parts can also cause squealing brakes. For instance, some cars, like the Subaru Tribeca, may have brake components made of metal and synthetic materials that create friction noise. Ensuring that you have a suitable brake pad material can reduce this problem.

New Brake Installation

Sometimes, the issue arises after new brakes are installed. If the old rotors aren’t cleaned or replaced, they can cause the new pads to squeak. Always make sure the servicing includes proper rotor maintenance to avoid this.

 Lack of Lubrication

Lack of lubrication can commonly cause squealing brakes, mainly if your vehicle uses drum brakes. In drum brake systems, the brake shoes press against the drum to slow down the car. These shoes must move smoothly against the backing plate, and lubrication is crucial in ensuring this happens without noise.

When insufficient lubrication, the brake shoes scrape against the backing plate. This metal-on-metal contact creates a squealing sound. Over time, this can be annoying and cause wear and tear on your brake components.

Applying brake lubricant to the contact points where the brake shoes and backing plate meet is essential to fix or prevent this issue. Here’s how you can do it:

  1. Locate the Drum Brakes: First, you must access your vehicle’s drum brakes. This usually involves removing the wheel and the drum itself.
  1. Identify Contact Points: Look for the areas where the brake shoes touch the backing plate. These are the points that need lubrication.
  2. Apply Brake Lubricant: Use a high-quality brake lubricant and apply it to these contact points. Make sure to apply a thin, even layer.
  3. Reassemble: Once the lubrication is applied, reassemble the drum and wheel, ensuring everything is securely in place.
  4. Test Drive: After reassembling, take your car for a test drive to ensure the squealing noise is gone.

Braking Style

Your braking style can also contribute to squealing brakes at low speed. Harsh and quick braking can generate excessive heat, causing the brake pads to glaze. This smooth, hard glaze reduces friction, leading to noise and reduced braking efficiency. To prevent this, avoid riding the brakes downhill and practice gentle braking.


Moisture from rain, snow, or humidity can be a common cause of squealing brakes at low speed. When your car is exposed to wet conditions overnight, a thin layer of rust can form on the brake rotors. This rust is usually harmless but can create a squeaking sound when using the brakes.

When water from rain or humidity comes into contact with the metal surfaces of your brake rotors, rust can form. This is especially true if your car is parked outside in damp conditions. The rust can cause the brakes to squeak when stopping slow because the brake pads are rubbing against the uneven, rusty surface of the rotors.

The good news is that this type of squeaking is usually temporary. As you drive and use your brakes, the friction between the brake pads and the rotors will typically wear off the rust. After a few stops, the squealing should disappear as the rust is removed.

To prevent rust and the resulting squealing brakes, consider these simple steps:

  • Park your car in a garage or covered area to protect it from moisture.
  • Try to drive your car regularly, even for short trips, to prevent rust build-up on the rotors.
  • After driving in wet conditions, gently apply the brakes a few times to help dry off the rotors and pads.

How to Stop Low Speed Brake Squeal

Are you tired of hearing your squealing brakes at low speed? It can be frustrating and sometimes concerning. Here’s a simple guide to help you stop that annoying noise and ensure your brakes are in good shape.

Firstly, it’s essential to know that securing the pads more tightly onto the caliper will not solve the problem. It can make the noise even louder. So, what can you do?

Change the Brake Pads and Rotors

One effective solution is replacing the brake pads and rotors if worn out. Look for signs of excessive wear, such as brake pad dust on the wheels. If the remaining lining on your brake pads is too thin to last until the next servicing, it’s time for new ones. Changing these parts can often stop the brakes from squeaking at low speeds.

Use Pad Shims and High-Temperature Grease

Another method to stop squealing brakes at low speed is to use pad shims and apply high-temperature grease. Shims are thin metal or rubber adhesive pads that buffer between the brake caliper and the pads. They help correct minor differences between these components, reducing vibrations and noise. Applying high-temperature grease between the caliper and pads can also help isolate vibrations and decrease the squeal.

Regular Maintenance

Regular maintenance is important for preventing squealing brakes when stopping slow. Ensure that all brake components are properly lubricated and in good condition. Suppose you’ve recently installed new brakes, and they squeak at low speed. In that case, it might be because the rotors were not properly cleaned or replaced during installation. Make sure that any new brake installation includes rotor maintenance to prevent squeaking.

Addressing Environmental Factors

Sometimes, environmental factors like moisture can cause temporary squealing brakes. If your car has been exposed to rain or humidity overnight, a thin layer of rust can form on the rotors. Everyday driving usually wears this rust away. However, you can also park your car indoors to prevent moisture build-up.

How Much Does It Cost to Replace Brake Pads and Discs?

The cost of replacing brake pads and discs can vary greatly depending on your car. For example, replacing the brakes on a high-performance car usually costs more than on a regular hatchback. Here’s what affects the cost and what you need to consider:

Car Make and Model

The type of car you drive affects the cost of brake replacement. High-performance cars have more advanced and expensive brake systems compared to standard vehicles. These brakes are designed to handle higher speeds and more challenging driving conditions.

Frequency of Replacement

Different cars need their brake pads and discs replaced at other times. Some vehicles require more frequent replacements, which can cost more over time. Check your car’s manual to see how often you should replace the brakes.

Quality of Brake Components

The quality of brake pads and discs also affects the cost. Higher-quality parts are made from better materials and have been tested more thoroughly. These parts can be more expensive but usually last longer and perform better. High-quality brake pads can reduce the chances of squealing brakes at low speed.

Average Cost Estimates

On average, replacing brake pads costs between $150 and $300 per axle, depending on the quality of the pads and the type of vehicle. Replacing brake discs (rotors) can cost between $200 and $400 per axle. So, a complete brake job, including both pads and discs, can cost between $350 and $700 per axle.

Additional Factors

Labor costs vary depending on where you go. Dealerships often charge more for labor than independent repair shops. Also, if your brakes are squealing at low speed, you might need new pads and discs sooner, affecting your budget.
