Are rusty car brake discs dangerous?
If rust on car brake discs is too thick, it will directly affect the operation and also directly affect the car's deceleration ability.
Disc brakes on cars are the most commonly used type of brake today thanks to advantages such as low cost, high braking performance, light weight, open design for good heat dissipation, and easy maintenance. These brake discs are often made of metal that is susceptible to oxidation, leading to rust.
When this steel part is exposed to oxygen and external agents (such as dust, water, soil, rain...) for a long time without being cleaned, oxidation will occur, leading to rust. If your car is using a brake disc made from Carbo ceramic material, you can be completely assured because this material helps your car's brake disc not rust.
Rust on car brakes affects driving safety as well as operating efficiency, the risk of collision and traffic accidents is very high. If it is just a thin layer of rust and newly formed, it is not a cause for concern. However, if the rust layer has formed and adhered to the brake disc for a long time, the brake disc should be replaced or if it is more serious, the entire car brake needs to be replaced.

How to deal with rusty car brake discs
Get in the car and start the engine, let the car run a few laps to rub the brake disc and brake pads against each other, thereby removing the rust layer on the brake disc. You can spray directly on the brake disc with a specialized car brake disc cleaning solution, let the car dry before continuing to use the car to avoid water stagnation causing rust.
Regularly bring your car to an auto care center for periodic maintenance to quickly detect problems your car is having and find the fastest solution.
If your car's brake discs are too rusty, take your car to an auto service center to have them replaced with new ones, to protect your life and that of your loved ones when using your car.
