Nobody like to hear squeaks coming out of the car and if your car is one of them which is producing squeaking noise while driving but no brakes applied, then this post is for you. We will share with you the root cause and fix for the issue.
When you hear a squeaking or squealing sound coming from your brakes, the first thing that comes to mind is a worn brake pad but it could be one of several issues with your brake system.

Squeaking Noise While Driving But No Brakes Applied Why?
If you hear a squeaking noise while driving but do not apply the brakes, the brake caliper may be jammed or the brake wear indicator may be rubbing against the rotor. Over time, the pads thin, causing them to scrape against the rotor. This action causes a squeaking noise while driving.
Reasons Behind Squeaking-
Brake-related issues that can cause squeaky noises when the pedal is not applied are the brake wear indicator and stuck calipers.
1. Brake Calipers
A caliper is the main component of a car’s braking system. The brake pads and the associated brake assembly are housed in a caliper. If your caliper becomes stuck, it means the car is being driven with the brakes constantly applied.
This produces a very irritating sound. Another symptom is that the vehicle may pull to one side. The most common causes of brake caliper seizing are a lack of use and rust. Corrosion can cause brake rotors to become stuck to the pads.
Because brakes are subjected to a wide temperature range and are constantly exposed to the elements, corrosion can accumulate in these areas and cause the caliper to stick.
2. Brake Pads
Worn brake pads are the most obvious cause of brake squealing. This is due to the fact that brake pads are purposefully designed with a metal indicator that emits a high-pitched warning when they are approaching their minimum thickness.
That annoying screech is how you know it’s time to replace your brake pads. A thin layer of rust on your brake pads can cause squeaking noise while driving but no brakes applied. If the noise persists, have your brakes checked as soon as possible.
3. Suspension Error
Struts and shocks wear out over time, causing the car’s alignment to shift significantly. Whatever the cause, if the suspension is disrupted or lubricant has leaked away, the car will make noises.
When you accelerate or turn, the squeak usually becomes louder. If your ride is rough even on smooth roads, you have steering wheel wobble, and your vehicle pulls to the right or left, these are all signs of poor alignment.
4. Less Lubricant In The System
When metal-on-metal wear occurs in connections such as tie-rods, suspension joints, and steering linkage, squeaking suspension parts are frequently associated with a lack of lubrication. If lubrication is the primary cause of squeaking, a grease gun and some spray-on lubricant can be an easy and inexpensive fix; or, even easier, take your vehicle to an express oil change.
5. Grooves On Rotors
When your brake pads wear out, the rotors or discs begin to develop glazing, grooves, or irregular wear. When you replace your brake pads, make sure to do the following to your brake rotors. Rotors should be removed, measured, and machined or replaced. This results in a smooth, flat surface.
If you don’t remove or sand the glaze it causes a high-pitched squeal or squeak sound, especially when your brakes are cold.
Fixing The Squeaks
Fixing the issue which is causing high-pitched noise while driving is very important as it may cause safety issues for the driver or may cause serious damage to the vehicle
1. Replacing Brake Pads
If your brake pads are squealing or grinding, it may be time to replace them. You’ll be surprised to learn that you can replace the pads in your car’s disc brake system quickly, easily, and without the use of specialized tools. And it may fix the issue causing squeaking noise while driving but no brakes applied
1. Take Off The Wheels
Loosen the wheel’s lug nuts. Then jack up the vehicle and place a jack stand beneath the vehicle’s frame.
2. Take Out The Slider Bolt
Locate the two slider bolts (also known as “pins”) that hold the caliper in place. It may be long, but once fully loosened, it will easily slide out.
3. Raise The Brake Caliper.
The brake caliper pivots up after the bottom bolt is removed. It is now very simple to inspect the thickness of the brake pads to confirm that they need to be replaced. The majority of brake pads have metal wear indicators.
4. Remove The Old Brake Pads.
The brake pads are now exposed, and the retaining clips hold them in place only loosely. Simply remove the old brake pads.
5. Insert The New Brake Pads.
The new pads slide into place just as easily as the old ones did when they were removed, though the new clips are sometimes tighter. The new pads’ ears should fit snugly into the brake grease you applied.
6. Apply The Brakes Piston
As the pistons are pushed back, the brake fluid level gradually rises. Check the master cylinder reservoir frequently. As the pads wear, the fluid level naturally decreases. And it returns when the pads are replaced.
7. Adjust The Caliper
With the pistons retracted, the caliper should slide easily over the pads. The fit is sometimes too tight, and the caliper will slide on the newly installed brake pads.
8. Replace The Slider Bolt.
Replace the slider bolt and tighten it again. Remount the tire and tighten the lug nuts after straightening the wheels.
2. Removing Rust From the Calliper
Step 1: To begin, we want to ensure that the surface is clean so that the new coating adheres to the brake caliper. If you have surface rust or corrosion, use a wire brush and/or 500-1000 grit sandpaper. Scuff the surface of the brake caliper to give it a dull sheen.
Step 2: Using a brake cleaner, spray your calipers to get rid of any remaining dirt, grime, or grease on the caliper.
Step 3: Apply 1-2 coats of primer with a high-temperature primer. Light and even coats are essential for success here, and you should wait about 10 minutes between coats.
