Hidden inside the wheel, the brake pads, thinner than a finger, are crucial for both stopping and controlling the vehicle.
Many truck drivers only know how to maintain the wheels, but they don’t realize that the most important part to protect is this small component—if it rusts, the brakes are ruined.

Environmental Catalysis of Rust: Rust Equals Failure
The brake pads are inherently vulnerable. Rain, car washes, and puddles all contribute to this problem; the brakes get so hot they could fry an egg, and in sub-zero temperatures, condensation seeps out; de-icing agents and coastal salt spray further damage metal; even the best rustproofing will fail if neglected.
Once the brake pads rust, problems follow. If they don’t turn, the pads rub unevenly against the bulge, making a squeaking noise; if they rust completely and become stuck, the pads won’t adhere properly, resulting in a delayed braking response; uneven rust on both sides leads to uneven braking force, causing the truck to swerve during emergency braking; if they don’t return to their original position, they wear down continuously, requiring pad replacement after only a few thousand kilometers.

Brake Maintenance: More Than Just Oiling
Brake pins are inherently vulnerable. Rain, car washes, and puddles all contribute to water buildup in the brakes; brake pads get so hot they could fry an egg, and in sub-zero temperatures, condensation seeps out; de-icing agents in winter and salt spray from coastal areas further damage metal; even the best rustproofing will fail if neglected.
Once brake pins rust, problems begin. If they don’t turn, the brake pads rub unevenly against the bulges, making a squeaking noise; if they rust completely and become stuck, the pads won’t adhere properly, resulting in a delayed braking response; uneven rust on both sides leads to uneven braking force, causing the car to swerve during emergency braking; if they don’t return to their original position, they’ll wear down, requiring pad replacement every few thousand kilometers.
There’s no such thing as a “good enough” brake; the small brake pins are crucial to safety. Spending an extra half hour carefully inspecting them during wheel well maintenance could save you from a major accident. Next time you’re at the repair shop, remember to tell the mechanic to check the brake pins thoroughly.
