Does pulling the handbrake after riding in the rain cause the brake to rust?

Many drivers have encountered the phenomenon of the rear brake assembly locking up because the car had to wade through water in the rain. The phenomenon of locking up the brake due to pulling the handbrake for a long time occurs with both disc brakes and drum brakes. The reason is that when water enters with sand, dirt, and rust on the metal parts of the brake system, the brake pads may not release from the disc.

Experienced drivers in this case will handle by using a hammer wrapped in cloth and tapping lightly on the rim, brake disc a few times. The vibration can help the rust fall off, separate the disc and pads. Then get in the car, put the car in forward gear and press the gas, put it in reverse gear and press the gas again, doing this a few times will help the brake pads unstick. If these steps have been taken and the problem still exists, the driver should call a technician.

To reduce this risk, you can take several steps to maintain your brake system:

Dry the brakes after riding in the rain: After washing your car, driving in the rain or wading through water, gently apply the brakes over a long distance. The hot brake pads combined with the wind will quickly dry the brake assembly.

No need to pull the handbrake: If parking for a long time, P is enough to keep the car stationary. For manual transmission cars, you can park in 1st gear. To be more careful, use bricks or pieces of wood to block the wheels so the car does not move.

Periodic maintenance:Perform regular maintenance on your brake system, including inspecting and cleaning the brake discs, brake pumps, and other components. This helps keep your brake system working efficiently and reduces the risk of rust.

Use the handbrake properly: Avoid pulling the handbrake more than necessary. Make sure that the handbrake is only used when necessary and do not keep the handbrake engaged while the vehicle is moving.
