What are the causes of vehicle brake deviation?
2 Answers
Here are the reasons for vehicle brake deviation: 1. Irregular left-right deviation: Severe uneven tire wear, especially when the diameter difference between inner and rear tires is significant, leading to more pronounced irregular brake deviation. 2. Negative toe-in or loose components such as tie rod and drag link ball joints. 3. Sudden brake deviation: Sudden failure in the brake system or suspension components. 4. Regular directional deviation: Uneven clearance between the front wheel brake drum and friction lining, significant difference in contact surfaces of front wheel friction linings, different quality of front wheel friction linings, excessive difference in inner diameter of front wheel brake drums, or unequal return spring tension of front wheel brake shoes. Here are the solutions for vehicle brake deviation: 1. Proper tire allocation and rotation according to regulations to ensure uniform tire wear. 2. If tires wear normally but brake deviation still occurs, check for negative toe-in or loose components such as tie rod and drag link ball joints. 3. Strictly follow pre-trip and post-trip vehicle inspection requirements to thoroughly check the brake system and suspension components. 4. Check for oil leakage in the brake pipeline and ensure adequate tire pressure.
I've experienced brake pull several times. When braking on the highway, the car would suddenly veer to the right, which was terrifying. A common cause is uneven tire pressure between the left and right sides. For example, if the left tire pressure is low, the lack of traction during braking causes the car to pull to the left. Another reason is uneven wear on the brake pads, where one side wears out faster, reducing braking force and causing the car to pull to the opposite side. Suspension system issues are also common, such as a broken shock absorber leading to imbalance. Last time I checked myself, I found the wheel hub bearings were rusted and stuck; replacing them fixed the problem. During regular maintenance, always inspect the suspension arms and steering ball joints—if they're loose, braking can easily cause pulling. I recommend checking the braking system and tires every quarter—safety first, don't wait until an emergency stop causes an accident to regret it.
