5 Common Reasons Why Car Squeaks When Backing Up

Is your car making loud noises like squeaking when you are reversing it? In such a situation, the most obvious reason is faulty brakes. Your car shuddering and making a squealing noise when shifting the gear is also a common occurrence when your car has such an issue. However the problem is not that uncommon, so you are not alone. Knowing what are the reasons why a car squeaks when backing up can help you to diagnose and fix the issue as fast as possible. This article discusses the different reasons that cause such an issue so read on!

Reasons Why Car Squeaks When Backing Up

There is more than one reason why your car squeaks when backing up. It could be because of a piece of metal stuck in the transmission or on the wheels which is a simple reason and just removing the metal can fix the issue. However, there can be bigger reasons like faulty brake pads or other similar components which need an immediate fix to ensure both your and your car’s safety. 

Here are some common reasons that make cars squeak when backing up. 

1. Brake Pad Problems

If your car has worn out brake pads, they will rub against the rotor that creates squeaking noises when reversing it. When your brake pads are worn out, it can make your car shift completely in the opposite direction! This mostly happens when your car doesn’t have proper maintenance or the brake callipers and the pad surface have gone through a lot of movements and stress. Hence when the brakes shift, it ends up creating a lot of noise. 

How To Fix?

To fix the issue, the first thing you have to do is lubricate your brake pads by applying disc brake calliper lubricant. This will help in reducing the squeaking noise made by your car while backing up. If the squeaks persist, you may have to replace the brake pads. You can also try installing the anti-rattle clips. Many new vehicles are installed with these in their system to prevent the brakes from making any noise. So your car can squeak when backing up if the anti-rattle chips are absent or if they are wrongly placed. 

2. Inspecting The Brake Wear Pads

The wear tabs of the brake can be found towards the edge of the brake tabs of your vehicle. The purpose of the wear tabs is to make sure that the brake tabs are working properly. However, if your wear tabs are rubbing against the rotor, your car squeaks when backing up. That is the reason why car experts usually recommend that you should not start your vehicle by reversing it or by travelling long trips when you haven’t been driving your vehicle for a while. If the wear tabs are not positioned properly, you can expect to hear noises when you are backing up your car. 

How To Fix?

It is better to get your car checked and serviced when you experience such a situation with your car. The wear tabs should be inspected and repaired correctly and if needed, must be replaced. 

3. Lodging Of Metal In The Wheels Or Braking System

Squeaking noises are usually the result of metal rubbing against another metal. So if you are noticing that your car squeaks when backing up, it could be because of metal or a metallic object stuck between the rotor and the brake pads. Such disturbances can disable the system from working properly. 

Metallic objects can also get stuck in the wheels that make your car squeak when backing up. You may not notice any noise when driving forward as the obstructing object can be stuck in a specific manner. 

How To Fix?

When you hear squeaking noises from your car when reversing, it’s better to check the rotors and pads for a stuck metallic object first. This is the most simple cause to fix. Cleaning them can ensure that any foreign object is removed from the rotors and pads. 

You can also check the wheels for any metallic object that shouldn’t be there and remove it. You can also check for any probable damage that may be caused by the object in the wheels or brake pads. 

4. Lubricating The Grease Shims

The Grease Shims are found between the brake pads and the callipers. The purpose of the grease shims is to prevent any sort of noise from the brakes when they are used or when the different components rub against each other. However, if these grease shims have not enough grease, your brake will make squeaking noises, especially when backing up. 

How To Fix?

The fix for such a situation is quite simple. All you need is to lubricate the grease shin to provide it with enough grease for it to stop the brake system from making any noise while reversing. You have to lubricate the shims often to prevent the noise from occurring. The shims have two opposite sides that you must lubricate to ensure that the brake pads won’t get worn out when working over them. However, you must not over lubricate the shims as it may ruin them. 

5. Transmission Issue

Another issue that makes your car squeak when reversing is a faulty transmission. However, transmission problems often cause different noises other than squeaking so this is a less probable cause of the issue. 

How Long Do Brakes Usually Last?

The lasting effect of your brake system depends mostly on how well you maintain them and your car. Otherwise, you needn’t be surprised if your car squeaks when reversing as you didn’t give it the care it deserved. Other than that, several factors determine how fast your car’s braking system wears out and these can differ from person to person and vehicle to vehicle as well. 

In general, high-quality brakes last between 30,000 to 50,000 miles if they were well maintained during their lifespan. However, determining how long your brakes last with just the mileage is not possible. Other factors that can help you determine how long your brakes last are

  • Driving condition
  • Frequency and style of the brake
  • Quality of the brake and its condition
  • The maintenance you give to your brakes


An issue with the braking system in your car can be the reason for a lot of noises made by your car. The case of car squeaking when reversing is not in any way different. Constant maintenance and repairing of your brakes are very important to ensure they work well.
