Causes of Rusty Car Brake Discs & Their Solutions

There are times when you may face the problem of rusty brake discs on your beloved vehicle. Many of you may even be surprised when you find spots on the surface of the disc. 

Rust usually appears when the vehicle is exposed to water, either from rain or due to washing. Then, after being exposed to water, the user does not use their car for a long time.

It is important to note that rust stains on this disc should not be left unattended to avoid worsening the condition. Because if the condition is severe, it could also affect the function of the car's brakes. 

Causes of Rusty Car Brake Discs 

The condition of rusty car brake discs should never be taken lightly as it can become a serious problem. In addition to disrupting the performance of the vehicle, it can also increase the risk of accidents while driving. 

As is known, car brake discs are a crucial part of the car's braking system because they ensure the vehicle stops properly. However, rust problems often occur on this component, and here are some causes that need to be understood. 

Due to Frequent Water Exposure

The main cause of rust spots appearing on the brake disc is due to continuous exposure to water. This exposure can trigger a chemical reaction between iron metal, oxygen, and water. 

If your vehicle often passes through humid areas or is parked in areas unprotected from rain, then it has a high risk of encountering this problem. Therefore, to avoid it, it is best to park the car in a place with minimal water exposure. 

Due to Dust and Dirt 

In addition to water, dust and dirt are also causes of rust on your vehicle. Dust and dirt can stick to the disc, leading to corrosion due to trapped moisture. 

Not Used for a Long Time 

Do you rarely use your car for mobility? If so, then the vehicle is very susceptible to rust. This is because there is no friction between the brake pads and the brake disc that can clean the surface of the disc from dust, dirt, and rust. 

Extreme Temperatures 

Both extreme hot or cold temperatures can also affect the integrity of the material on the brake disc. Not only that, drastic temperature changes can also cause structural changes in the disc metal, increasing the risk of corrosion. 

Solutions to Address Rusty Discs 

There are several symptoms that may indicate that the brake disc is rusted. For example, there is vibration when braking, the braking grip power decreases, and loud noises occur when braking. 

When the car disc shows the above signs, it is best to immediately seek solutions to avoid more severe damage. Below are several ways that can be used to address brake discs to prevent rusting:

• Make sure to clean this component regularly to help remove dirt, dust, and other residues.
• Perform regular maintenance to prevent rust on this component, including checking components or lubrication in the braking system.
• Store the vehicle in the right place to avoid extreme temperatures.
