Reasons for Brake Pulling
1 Answers
The main reason for brake pulling is the unequal braking force between the left and right wheels. Below is a detailed explanation of the causes: 1. Irregular left-right pulling: The primary cause of irregular brake pulling is severe uneven tire wear. The greater the diameter difference between the inner and outer rear tires, the more severe the irregular brake pulling becomes. This diameter difference causes the wheel's pressure on the ground to change with road irregularities. During braking, the braking torque on the wheels becomes severely imbalanced, resulting in irregular pulling. To avoid this phenomenon, tires should be properly allocated and rotated according to regulations to ensure even wear. If tire wear is normal but brake pulling still occurs randomly, check for negative toe-in or looseness in the tie rod or drag link ball joints. 2. Sudden brake pulling: Sudden pulling during braking is often due to sudden failures in the braking system or suspension components. Although such failures are rare, they are extremely hazardous and can lead to serious consequences if not handled carefully. The main causes of sudden brake pulling include: sudden failure of the brake pipeline on one side. For example, the pipeline may be dented due to squeezing or collision, preventing brake fluid or compressed air from passing through, or it may be blocked by excessive rust or dirt. Alternatively, the fixing bolts of the leaf spring on one side may loosen suddenly, causing misalignment between the front and rear axles and resulting in brake pulling.
