Why Shouldn't You Engage the Handbrake When Parking on Rainy Days?
2 Answers
The reason why you shouldn't engage the handbrake when parking on rainy days is that the handbrake and brake discs are prone to rust after coming into contact with water. Here is a detailed introduction about automotive brakes: Overview: Braking, also known as deceleration, refers to the action of stopping or reducing the speed of moving locomotives, vehicles, and other transportation tools or machinery. The general principle of braking is to fix a wheel or disc on the high-speed shaft of the machine and install corresponding brake shoes, bands, or discs on the machine base, which generate braking torque under external force. Brake Pads: Automotive brake pads, also known as brake linings, refer to the friction materials fixed on the rotating brake drum or brake disc of the wheel. The friction linings and friction blocks within them bear external pressure to generate friction, thereby achieving vehicle deceleration.
After years of driving, I've found that it's best not to engage the handbrake when parking on rainy days, mainly because the braking components are prone to rust and sticking in humid environments. The handbrake system consists of brake discs and brake pads, both made of metal. When rainwater or moisture seeps in and the handbrake is engaged, they press tightly together, preventing the moisture from evaporating and causing rapid rusting. Over time, the rust can cause the brakes to seize, making the wheels unable to move when starting the car, and may even damage the entire braking system, posing a safety hazard. I recommend choosing a flat parking spot on rainy days, shifting automatic transmission cars to P (Park), and manual transmission cars into gear to secure the wheels, eliminating the need to rely on the handbrake. Additionally, try to park in a sheltered area or use something to keep the brakes dry, preventing unexpected repairs.
