How to Solve the Problem of Wheels Not Moving After Rain?
3 Answers
Frequently move forward and backward about three times; Note: Do not repeatedly and forcibly drag the tires back and forth, as it may cause severe tire wear. Pour 100°C boiling water onto the position of the brake pads, then repeat method 1. The brake pads and brake drum will expand due to heat and automatically separate.
I encountered this situation after heavy rain last time, and it's mostly caused by rusted brake discs sticking together. Here are some effective tips for you: Never force the car to move, folks! When I first got my car, I foolishly stomped on the accelerator, and the tires ended up losing a layer of rubber. Now I've learned my lesson—when this happens, I gently rock the car back and forth to loosen the brake pads and discs. If that doesn’t work, try turning the steering wheel left and right; sometimes, the rust is stuck in a specific position and needs to be loosened. If all else fails, keep a rubber hammer in the trunk and lightly tap around the edge of the wheel a few times to shake off the rust. Remember to drive a few extra kilometers after rain to fully dry the brake system, so they won’t stick next time. By the way, here’s a little-known fact: parking on a slope makes this issue more likely, so try to find a flat parking spot whenever possible.
I've seen this too many times at repair shops. Rust-seized brake discs in rainy weather are most common, especially with cast iron discs soaked in water. When dealing with it, first check the temperature of all four wheels - the one that's warm is the seized part. Don't force towing; use an iron pipe over the wrench to increase leverage, then turn the hub bolts counterclockwise half a turn to break the rust layer. If parked outdoors frequently, apply special grease to brake caliper guide pins monthly, and apply anti-seize paste to the wheel hub center hole too. By the way, during recent rainy seasons many people switch to ceramic brake pads, but these are actually more prone to frost adhesion in low temperatures.
