What to Do When the Right Rear Tire of the Car Stops Moving?
2 Answers
For cars without ABS, if the brake pedal is pressed hard while driving, the wheel speed will rapidly decrease, causing the wheels to lock up. Fully locked wheels will drastically increase the friction between the tires and the road surface. If the front wheels lock up, the driver will lose control of the vehicle's direction, leading to skidding. Cars equipped with ABS continuously monitor the speed of each wheel through speed sensors installed on the wheels or drive shafts during emergency situations. The system then decides to increase or decrease the braking pressure, and the controller instructs the regulator to reduce the hydraulic pressure in the wheel's brake cylinder, thereby decreasing the braking torque.
Once when I was driving to the supermarket, I noticed that the right rear tire of my car wasn't moving—it seemed glued to the ground and wouldn't rotate at all. It gave me quite a scare, so I quickly pulled over to a safe spot. After checking, I suspected the brake caliper might have rusted and seized the wheel, with other common causes being a failed bearing or stuck brake pads. I tried gently pushing the car and heard a screeching noise, which confirmed it was a serious issue. I immediately called for roadside assistance. While waiting for the tow truck, I avoided driving further to prevent suspension damage. At the repair shop, replacing the caliper fixed the problem. Now, I get my brakes serviced every six months—washing the wheels and checking bearing lubrication—to avoid such headaches. If your tire locks up, stay calm and prioritize safety when handling it.
