What Happens to Car Brakes After Long-Term Inactivity?
2 Answers
Long-term inactivity of a car means the brakes are not used for an extended period, which may lead to wear or aging of the brake system. Below is a detailed introduction about car brakes: Overview: Braking, also known as deceleration, refers to the action of stopping or reducing the speed of moving locomotives, vehicles, other transportation tools, or machinery. The general principle of braking involves fixing a wheel or disc on the high-speed shaft of the machine and installing corresponding brake shoes, bands, or discs on the machine base, which generate braking torque under external force. Brake Pads: Car brake pads, also known as brake linings, refer to the friction materials fixed on the brake drum or disc rotating with the wheels. The friction linings and blocks bear external pressure to create friction, thereby achieving vehicle deceleration.
I have experienced situations where a car was left parked for extended periods. As a seasoned driver with years of experience, I can tell you that after parking for more than three months, the braking system undergoes noticeable changes. The brake discs develop surface rust, leading to squeaking or uneven braking, and sometimes the brake pads may stick. The first press of the brake pedal upon starting the car might feel unusually stiff or even unresponsive, which can be quite dangerous. The brake fluid may also degrade and absorb moisture, causing the hydraulic system to malfunction—resulting in a soft or overly stiff pedal, which affects braking performance. In humid regions, these issues are exacerbated, as rust and sediment buildup can cause components to seize. I recommend testing the brakes at low speeds a few times before driving, checking the brake fluid level and color. If it appears cloudy, don’t take risks—head straight to a professional shop for cleaning or fluid replacement. Safety comes first; don’t underestimate these seemingly minor issues, as they can lead to accidents. Regularly driving short distances can effectively prevent such problems.
