Squeaking Noise While Driving but No Brakes Applied

Many car parts can make you squeak while driving.  Sometimes these creaks can be a real threat, but not always.  There are many reasons a car may make a squeaking noise when driving, but the brakes are not working and may or may not be brake related.

Squeaking Noise While Driving but Not brakes applied new brake.

The most common cause of squeaking in a car is worn brake pads. Brakes sound a loud warning when replacing brakes to inform you that they have reached the end of their service life. Dirt build-up on the rotors can also cause brake noise.

The brakes can make a loud noise when the pads press against the rotor due to accumulated dirt. The brake callipers may also be stuck. There may also be unexpected alignment or fluid leaks from your car’s suspension or steering components.

A problem with the brake pads, calipers, rotors, or steering system can cause a creaking noise.  Debris, harsh weather, an overheated engine, or uneven tread wear are also possible causes. 

Let’s look closer at the causes of Squeaking noise while driving but no brakes applied.

Let’s start with the most common reasons first.  If you don’t put your foot on the brake pedal, braking is still the most common cause.

Brake related problems

Two brake-related issues that can cause squeaking noises when you’re not pedaling are brake wear indicators and stuck calipers.

  • Brake wear indicator

The brake wear indicator is one of the main causes of a continuous squeaking sound even when the brakes are not applied.  If the pad level gets too low, small metal protrusions called brake wear indicators rub against the rotor.  It causes a squeaking or creaking sound.

When the brake wear indicator rubs against the rotor, it makes a squeaking sound even when the brakes are not applied. Modern cars have sensors that tell the ECU when the brakes are worn out and need to be replaced.  A light will then flash on the instrument panel.

When that happens, small pieces of metal rub against the rotor and make an annoying noise. It is your signal to replace your brakes. A key indicator of this problem is when you hear a squeak while driving, but it gets louder when you hit the brake pedal.

  • Stuck caliper

The caliper is a major component of the brake system of an automobile. The caliper consists of the brake pads and associated brake assembly. A clogged caliper causes the vehicle to brake constantly.

It sounds very annoying.  Another symptom is that you may experience the vehicle pulling to one side.  If you keep driving, the rotor will get hot if you keep rubbing it, and in extreme cases, it could catch fire.

Lack of use and melted brake calipers are the most common causes of sticking. If the vehicle is left unused for several months, the brakes may jam, especially if the car is left outside in damp conditions. Brake rotors can corrode and stick to the pads or caliper pistons or slider pins can get stuck for similar reasons.

Brakes are subject to a wide range of temperatures, are constantly exposed to the weather, and rarely service or inspect between the pad and rotor changes.  As a result, corrosion can accumulate in these locations and cause the calipers to seize.

Besides the braking system, other causes include poor suspension, loose belts, poor lubrication of steering components, and poor wheel bearings.

  • Uneven tire tread

It is a very simple test that should do after moving on to other tests. Tire noise affects each tread pattern.  Sometimes it’s easy to spot uneven wear, but you may need to take a tire measurement to determine if it’s a new tire.

As the tire tread wears out, various sounds indicate tire wear.  One tire can make a repetitive noise. New tires can fix the squeaking sound but not the root cause, which could be a suspension or alignment problem.

  • Tire inflation

People often need to pay more attention to ensuring that all tires carry the same air pressure as the manufacturer recommends.  If one or more tires have a different pressure than the others, the vehicle will become unbalanced, and stress on one or more tires will increase, causing wear.

This shortens tire life and creates a loud noise, especially when turning and cornering.  Inflate your tires regularly to the recommended inflation pressure to ensure your and your vehicle’s safety and extend tire life.

  • Bad Alignment/Suspension

It is more likely to happen if you are in an accident or hit a pothole. Another cause is a lack of lubrication due to leaking fluid at joints such as CV joints or U-joints. Struts and shocks wear over time, significantly changing the vehicle’s alignment. If for some reason, the suspension fails or the oil leaks, the car will make noise.

The noise often increases when accelerating or turning. If you drive rough on a flat road, the steering wheel shakes, and the car pulls to the right, or left is a sign of misalignment.

  • Loose Belt

Another cause of car noise is a loose or worn belt. There are mainly two types of belts in automobiles.  Let’s focus on the serpentine belt.  A timing belt or chain does not make a squeaking noise.  It’s more of a slap, and it’s related to many other engine issues like rough idling and stalling.

A serpentine belt, also known as a drive belt, is a single belt that connects several components of an engine, such as the steering, crankshaft, water pump, AC fan, alternator, etc.
The average life is 100,000 miles at maximum.  Then it gets loose from wear and tear. The noise increases when accelerating hard, slowing down the vehicle or turning on the air conditioner.

Accelerating or revving the air conditioner puts more stress on the belt, resulting in a loud noise.  Belts are more likely to creak when starting or in damp environments where moisture can easily escape.

  • Steering gear

Sometimes the steering system makes a rattling noise in the car.  It can happen when the power steering fluid level drops. Similarly, another cause could be that parts such as ball joint seals are dry and rattling due to a lack of lubrication.

Therefore, if you hear noises when turning, you must replace the steering wheel or lubricate the steering parts.  Inspecting these parts can be challenging.  Especially if you don’t like getting under the car or the idler arms are greased and leaking.

Why does the squeaking sound stop when braking?

When you apply the brakes, the noise you make affects where the brake noise comes from when you’re not braking. The wear indicator makes the same noise whether or not the brakes are applied.

A stuck caliper usually kisses the rotor and screams when the brakes aren’t applied.  However, as the force increases, it grips tighter, and the clutch disappears until you take your foot off the brake pedal.


Q. Why do I hear a squeaking noise when I drive?

⦁ The most common cause of a car squeaking noise while driving is worn brake pads.  The brake pads notify you when to replace them with a beep when you apply the brakes as a gentle reminder that it is time to check your brakes.

Q. Why is my car squeaking if my brakes are fine?

⦁ Over time, your car’s rotors can lose their smoothness, which is another common cause of squeaking brakes.  Rust and other debris can cause creaking noises.  If this is a problem with your vehicle, you can get it rusted or rusted out by a local mechanic.

Q. Is it bad if your car squeaks while driving?

⦁ The suspension system absorbs shocks and vibrations from bumps, potholes, and other imperfections on the road.  It usually provides a smooth ride, but if there is noise, it may indicate worn springs or shock absorbers.  It is best left to a qualified technician.

Q. Is it expensive to fix squeaky brakes?

⦁ Take your car to a professional as soon as you hit the brakes.  A typical inspection costs between $80 and $115, depending on labor costs.  Depending on your car model, replacing a set of new brake pads can cost nearly $300 per axle in parts and labor.

Q. Is there a spray for squeaky brakes?

⦁ Presto Anti-Squeaking Spray prevents annoying brake squeaks that occur between the brake caliper piston or bearing points and brake pads.


If you step on the brake pads while riding, they need to be replaced, but the brakes do not work.  The brake wear monitor is a metal clip that presses on the brake pads and rubs the rotor.
