Why is My Car Squeaking? Check if it’s Your New Drum Brakes

Drum brakes are a system used in many vehicles to help slow and stop the vehicle. When working properly, drum brakes are quiet and reliable. However, if the drum brakes begin to squeak, it is an indication that there is a problem with the braking system that needs to be addressed. The cause of new drum brake squeaking can range from inadequate lubrication on components to worn brake shoes or drums. It is important to have a qualified mechanic inspect your drum brakes if they start to squeak in order to determine the exact cause and make sure that the brakes are functioning properly.

Automobile: New Drum Brakes Squeaking

Drum brakes are an integral part of any automobile, providing the vehicle with effective and reliable braking power. When drum brakes begin to squeak, however, it can be a sign of a larger problem. In order to identify and address the issue, it is important to understand the components of drum brakes and the potential causes of squeaks.

Components of Drum Brakes

The components of drum brakes include an auxiliary shoe, primary shoe, wheel cylinder, adjuster mechanism and return springs. The auxiliary shoe is designed to apply pressure on the inside surface of the wheel cylinder when the brake pedal is depressed. The primary shoe is designed to provide additional pressure on the outside surface of the wheel cylinder when the brake pedal is depressed. The wheel cylinder contains a pair of pistons which are actuated by hydraulic pressure from a master cylinder, pressing against both shoes at once. The adjuster mechanism is designed to ensure that there is sufficient tension in both shoes during operation, while return springs help return both shoes to their original position after each use.

Causes of Squeaking Drum Brakes

There are several potential causes for squeaking drum brakes. Worn out components can cause issues such as worn primary or auxiliary shoes which can create friction between them and cause squeaking noises when applied. Moisture build up in an assembly can also lead to squeaks due to corrosion or rust on certain components. Finally, rigidness in an assembly can cause components to rub together and create unwanted noise as well.

Identifying Squeaks from Drum Brakes

In order to identify whether or not a squeak is coming from your drum brakes or another component, it’s important to pay attention to the frequency of the noise. If you hear a steady high-pitched squeal that occurs every time you press down on your brake pedal then chances are it’s coming from your drum brakes and should be addressed immediately before further damage occurs.

Maintenance Tips for Drum Brakes to Avoid Squeaking

Regular maintenance is key to ensuring that your drum brakes remain in good working order and don’t start producing that dreaded squeak. Before you begin any maintenance, make sure the brakes are cooled off and that you wear gloves when handling them. Here are some tips to help keep your drum brakes running smoothly:

Regular Checks for Wear and Tear

It is important to check the brakes regularly for any signs of wear and tear, such as cracks, rust, or other damage. If you find any of these signs, replace the parts immediately. Check the brake lining for wear as well; if it appears thin or worn out, replace it. Additionally, inspect the wheel cylinders and brake shoes for any leaks or damage. If you notice anything amiss, have a professional mechanic take a look at it before continuing with maintenance.

Lubricating the Moving Parts

In order to keep your drum brakes running smoothly, make sure to lubricate all of the moving parts regularly. Use a high-temperature lubricant on the wheel cylinder pins, adjusters, and other moving parts as recommended by your vehicle manufacturer’s instructions. This will help prevent rusting and squeaking of the parts due to friction or lack of lubrication.

Replacement Tips for Worn Out Parts of Drum Brakes

When replacing worn-out parts in your drum brakes system it is essential that you select the right replacement parts that are compatible with your vehicle model and provide optimal performance. Here are some tips on selecting replacement parts:

Matching The Size And Specifications

The size and specifications of each part must match those specified by your vehicle manufacturer in order to ensure proper fitment and performance. Make sure to double-check all measurements before buying replacement parts so they can be properly installed on your vehicle without issue.

Checking Compatibility With Vehicle Model

It’s important to verify compatibility between replacement parts and your vehicle model before purchasing them. Make sure that all components are compatible with each other so they can be installed without issues down the road.

Reading Product Reviews

Before buying replacement parts for your drum brakes system, read reviews from people who have used them in similar applications as yours so you can get an idea about their performance before making a purchase decision. This will help you make an informed decision about what components will work best for your needs.

Consulting Professional Mechanic Or Manufacturer

If you’re unsure which components are compatible with each other or if installation requires special tools or expertise, consult with a professional mechanic or manufacturer directly before making any purchases as they will be able to advise you on what products best suit your needs in terms of fitment, performance and price point.
