What is the best solution for rear wheel lock-up?

The best solution for rear wheel lock-up: Pour 100-degree boiling water onto the brake pads, then repeatedly move forward and backward about three times. Rear wheel lock-up mostly occurs after heavy rain or car washing, mainly caused by the expansion of water entering the rear wheel brake drum. When the rear wheels lock up, park the car on level ground, avoiding slopes if possible. After turning off the engine, shift into first gear to prevent the car from moving, and do not engage the handbrake when parking. This prevents the friction pads from contacting the brake drum during parking, thereby avoiding adhesion between the friction pads and the brake drum that causes lock-up.
I remember last summer on the highway, my car's rear wheels suddenly locked up, almost causing me to lose control. It gave me quite a scare. Afterward, I talked to a mechanic and learned that this is a common issue caused by stuck or rusted brake pads, especially after rainy days or long periods of inactivity. The best solution is to stay calm, avoid slamming on the brakes to slow down, turn on the hazard lights, and gradually pull over to the side. Once safely stopped, try gently pressing the brake pedal a few times to release the pressure, or lightly tap the brake drum with a wrench to loosen the jam. If that doesn’t work, don’t push it—call a tow truck immediately and take it to a professional repair shop. The fix is usually simple, involving cleaning or replacing parts. Now, I make it a habit to check the brake system monthly for rust prevention, reducing the risk of lock-ups and ensuring safety.
