What Happens When the Front Wheels Lock Up?

[SiennaDella]

When the front wheels lock up, the driver loses control over the vehicle's direction. Below is relevant information about wheel lock-up: 1. Meaning of wheel lock-up: Wheel lock-up refers to the phenomenon where, during braking, the wheels stop rotating and slide on the road surface due to the braking torque. This causes the wheels to lose their ability to resist lateral forces, making the vehicle prone to skidding or losing control. 2. Causes of wheel lock-up: (1) Prolonged parking: If the parking brake is applied when there is water in the brake drum after washing the car or rain, the wheels may lock up over time. Using the vehicle's power to move the tires can help. (2) Stuck or non-returning brake master cylinder cup: The solution is to clean the entire brake system and replace the brake master cylinder cup. (3) Non-returning brake caliper: This can be fixed by sanding with sandpaper and applying grease. If the caliper itself is faulty, it may need to be replaced. (4) Frozen brake pads due to ice: Melt the ice with hot water or gently tap the brake drum with a blunt object like a hammer. (5) Overheating from prolonged braking, causing the brake pads to fail to separate: Depending on the situation, the brake pads may need to be sanded or replaced.
