Is It Normal for Brakes to Lock Up on Rainy Days?

Yes, it is normal. If your car's brakes lock up on rainy days, you can try repeatedly moving forward and backward about three times. If this doesn't work, pour 100°C boiling water over the brake pads and then repeat the previous method. The brake pads and brake drum will expand due to heat and automatically separate. Alternatively, you can remove the tire and tap the brake drum to loosen the adhered brake shoes and drum. Below is some relevant information about brake lock-up: 1. Solution: Use ABS (Anti-lock Braking System) technology. The main feature of this technology is that during emergency braking, the wheels do not completely stop rotating. This ensures that the vehicle does not experience sliding friction with the ground, preventing loss of control and avoiding tire blowouts due to sliding friction. 2. ABS Working Principle: The ECU (Electronic Control Unit) controls the ABS actuator to increase, maintain, or reduce the brake fluid pressure for each wheel. Each wheel is equipped with a speed sensor that sends the wheel's speed signal to the ECU. If excessive braking force risks causing wheel lock-up, the ECU sends a signal to the ABS actuator to reduce brake fluid pressure. Once the nearly locked tire is released from braking, it naturally regains traction control.
I remember that rainy day when I was driving, and the brakes suddenly locked up, the wheels locked directly, and the car skidded on the road, almost causing an accident. Normally, ABS should prevent this situation, but that day it didn't work, possibly due to water entering the sensors or wiring issues. On rainy days, there's more water, and the road surface is slippery. If ABS fails, brake lock-up is more likely to cause loss of control, which is definitely not normal. Brake lock-up is dangerous even on sunny days, but the risk is greater in the rain. I suggest that if you encounter this, slow down and pull over, then immediately check the anti-lock braking system and brake components. Regular maintenance can reduce such problems, such as cleaning sensors and checking brake fluid. Don't ignore it; safety comes first.
When I'm driving, brake lock-up is definitely abnormal in rainy conditions. The anti-lock braking system (ABS) is designed to prevent wheel lock-up, especially on slippery surfaces, by rapidly adjusting brake pressure to maintain traction. If lock-up occurs during rain, it indicates the ABS isn't functioning properly, possibly due to sensors being obscured by water or module failure. Additionally, worn brake pads or poor tire drainage can exacerbate the problem. You should get it checked promptly, otherwise skidding and loss of control become likely. Maintaining vehicle upkeep is crucial – inspect the brake system more frequently during seasonal changes to avoid failures at critical moments. Driving in rain already means poor visibility, and brake issues make it even more dangerous, so don't delay, get it repaired promptly.
Brake lock-up in rainy weather is absolutely not right. ABS should automatically prevent wheel lock-up to avoid skidding on wet roads. If the wheels lock up, there might be a system malfunction or issues with brake components. Driving under such conditions is highly risky, as the rear of the car may swing uncontrollably, increasing the chance of collisions. It's safer to stop the vehicle promptly.
