What phenomena are prone to occur when the rear wheels lock up?

Car will be unable to drive normally. Specific reasons: If the left rear wheel of the car locks up, it is due to excessive wear of the vehicle's brake pads. This causes the brake caliper in the braking system to extend too far and fail to retract naturally, leading to jamming. At this point, the vehicle's brake pads are in a locked state, naturally causing the wheel to lock. Simply replacing the vehicle's brake pads will resolve the issue. Main advantages: The master cylinder rubber cup may become stuck and fail to return to its original position, causing the rear wheels to lock. This could be due to water or other impurities entering the braking system, or failure to clean the system thoroughly before switching to a different brand of brake fluid, causing the master cylinder rubber cup to swell and resulting in the rear wheels of the car locking up.
When the rear wheels lock up, I notice the car is prone to losing control, especially during hard braking or on slippery roads. The rear end suddenly swings to one side, as if pushed, creating a high risk of skidding. The braking distance also increases because the tires aren't rolling but dragging, not only failing to stop but also wearing down the tread. I think this issue is most dangerous on curves, easily causing spin accidents—like what I experienced on the highway, almost hitting the guardrail. For prevention, the ABS system is very effective; it prevents lock-up and allows the wheels to keep rotating. It's advisable to regularly check brake fluid and wheel hubs to ensure the braking system functions properly—don't ignore it to save money. If you notice abnormal brake noises or a stiff pedal, get it fixed early—safety first.
