What are the causes of vehicle braking deviation?
2 Answers
Here are the reasons for vehicle braking deviation: 1. Irregular left-right deviation: Severe uneven tire wear, especially when the diameter difference between the inner and rear tires is significant, leading to more severe irregular braking deviation. 2. Negative toe-in or looseness in the tie rod and drag link ball joints. 3. Sudden braking deviation: Sudden failure in the braking system or suspension components. 4. Regular directional deviation: Uneven clearance between the front wheel brake drums and friction linings, significant difference in the contact surfaces of the front wheel friction linings, different quality of the front wheel friction linings, excessive difference in the inner diameter of the front wheel brake drums, and unequal spring tension of the front wheel brake shoe return springs. Here are the solutions for vehicle braking deviation: 1. Reasonable tire allocation and rotation as per regulations to ensure uniform wear. 2. If tires wear normally but braking deviation still occurs, check for negative toe-in or looseness in the tie rod and drag link ball joints. 3. Strictly follow the vehicle inspection requirements before and after trips to thoroughly check the braking system or suspension components. 4. Check for oil leakage in the wheel brake pipelines and ensure adequate tire pressure.
I've encountered brake pull issues many times, most commonly due to uneven tire pressure or uneven tire wear. I remember one time when the car was pulling to the right, and upon inspection, I found the right tire pressure was 10 psi lower than it should be. After adjusting it, the problem was immediately resolved. Another cause can be stuck brake calipers, where the piston doesn't move smoothly, leading to uneven braking force. Issues with the suspension system, such as loose tie rods or leaking shock absorbers, can also cause the car to wobble when braking. If the wheel alignment is off with significant angle deviations, the pulling becomes even more noticeable. I recommend checking tire pressure monthly with a gauge and inflating if unbalanced. If the problem persists, take the car to a repair shop to check the calipers and alignment. Don't overlook small details, as they can pose significant risks. Safe driving starts with the basics.
