The causes of braking deviation are as follows: 1. Incorrect installation of the brake lines. This usually occurs after vehicle repairs. During driving, if the front wheels brake before the rear wheels, when the rear wheels brake first, the vehicle will experience a "fishtail" phenomenon, causing the rear side of the vehicle to deviate. During vehicle maintenance, especially after repairing an accident-damaged vehicle, mechanics might incorrectly install the front and rear brake lines, causing the rear wheels to brake before the front wheels. 2. Malfunction of the Anti-lock Braking System (ABS). The ABS system controls the distribution of braking force to each wheel by receiving speed signals from each wheel, keeping the wheels in a state close to "locking" but not actually locking. This enhances braking force while still allowing directional control.

I often help friends diagnose the issue of brake pull, and the most common cause is an imbalance in braking force between the two sides. For example, uneven tire pressure—when there's a significant difference in pressure between the left and right tires, the car will pull toward the side with lower pressure during braking. Brake pads may also wear unevenly, with one side thicker than the other, especially on the left side, which tends to wear out faster due to driving habits like frequently riding on one side of the road. Hydraulic system leaks or blocked brake lines can lead to inconsistent pressure, affecting braking force. Suspension components like failed shock absorbers or worn bushings can also cause pulling. I recommend checking tire pressure and brake pad thickness monthly, and if there are any unusual noises, take the car in for repairs. I’ve encountered several cases where owners delayed repairs, leading to accidents—safety is no small matter, so regular maintenance is crucial.

Last time my car pulled to one side when braking on the highway, which gave me quite a scare. The inspection revealed severe wear on the front right tire due to uneven load distribution from frequent city driving and improper tire pressure. The brake pads were also asymmetrically worn, and the issue was resolved by simply replacing them with new ones. When encountering water puddles or oil stains on the road, differences in tread depth can cause momentary uneven grip, but persistent pulling warrants investigation. Experience has taught me to check tire pressure monthly and rotate tires every 10,000 kilometers to balance wear. Don't just replace some brake pads—replace them in pairs. Drive with gentle braking, avoiding sudden stomps. These habits reduce risks, save money, and provide peace of mind.

Brake pulling is quite dangerous, as it can easily lead to loss of control and skidding during emergency braking, resulting in accidents. The causes are often related to the braking system, such as a faulty brake caliper or uneven wear of brake pads, leading to uneven braking force. Uneven tire pressure or inconsistent tread depth can also cause imbalance. Hydraulic leaks are another common hazard. If brake pulling occurs, immediately slow down and pull over—don't push on. I emphasize the importance of regular maintenance, checking brake fluid and suspension at least every six months to detect and fix issues early. Safety first—prevention is better than cure.
