What are the phenomena of brake deviation?

[McCaroline]

Brake deviation phenomena include: 1. The car deviates irregularly to the left or right during driving, or shows regular directional deviation; 2. Rear axle sideslip or front wheels losing steering ability, causing the car to lose control and deviate from the original driving direction; 3. Body sway during braking; 4. A feeling of the steering wheel being pulled. The causes of brake deviation are: 1. Inconsistent braking force on both sides of the car's wheels, especially the wheels on both sides of the steering axle; 2. Incoordination of the suspension guide rod and steering system linkage during braking; 3. Improper loading on both sides of the vehicle; 4. Inconsistent road adhesion on both sides.

Having driven for decades, I can spot brake pull at a glance. The most common symptom is when you hit the brakes, the car suddenly jerks to one side as if someone is yanking the steering wheel. Especially on the highway, even a light tap on the brakes can make the whole car veer sharply left or right—you’ve got to grip the wheel tightly to keep it steady. Cold starts make it worse; the pull is more pronounced during the first few brakes but might ease up after driving a bit. You might also hear squealing from the tires or brake pads, or feel excessive steering wheel vibration. These are telltale signs of issues like uneven braking force between the wheels or worn-out suspension components needing adjustment. My advice? Get it checked at a repair shop ASAP. Ignoring it not only accelerates tire wear but also turns every drive into a white-knuckle ride!

Experiencing brake pull while driving can indeed be quite dangerous. The most obvious sign is when you apply the brakes on slippery roads or downhill slopes, you feel the car uncontrollably veering to one side, and the steering wheel's resistance becomes lighter. Sometimes, there's also a slight sticking sensation when pressing the brake pedal, as if one side engages first. In such cases, it's essential to check if the brake pads are wearing evenly—for instance, if the left side wears less than the right, it can cause an imbalance. Significant differences in tire pressure or wheel hub deformation are also common causes. I once encountered this situation on the highway and nearly scraped the guardrail. Since then, I've made it a habit to check tire pressure every quarter and inspect brake pads during seasonal changes. These small actions can be lifesavers.

Brake pull during driving has several typical manifestations. For instance, when braking normally during straight-line driving, the car immediately veers to one side instead of stopping straight, accompanied by slight steering wheel movement. Another scenario is noticeable body tilt during emergency braking, along with abnormal tire screeching sounds, which is more pronounced on bumpy roads. Often, this is caused by stuck brake pads on one side or uneven caliper rusting, leading to imbalanced braking force on both sides. If left unaddressed, tire lifespan will shorten over time, and safety risks will skyrocket. Remember to have a professional shop inspect the wheel cylinders and brake fluid condition early.
