What Causes the Vehicle to Pull to One Side When Braking?
2 Answers
The reason for the vehicle pulling to one side when braking is: uneven braking force between the left and right sides. When this occurs, it is necessary to visit a professional institution for adjustment. The braking system of a car is extremely important as it directly affects the vehicle's driving safety and stability. The braking system mainly consists of a vacuum booster pump, master brake cylinder, brake caliper, brake pads, and brake discs. Below are the maintenance methods for the braking system: 1. Use a professional brake disc cleaner. Before use, shake the liquid in the can thoroughly, then spray it directly onto the area to be cleaned until dust and oil stains are completely removed. Wipe clean with a clean towel, leaving no dust or residue. 2. Use a professional brake caliper guide pin lubricant. Wear a single-finger glove and apply the product evenly on the surface of the brake caliper guide pin and inside the guide pin groove. Do not mix with other mineral lubricating oils. 3. Use a professional high-temperature resistant brake pad protector. Wear a single-finger glove and apply the product evenly on the back of the brake pads and inside the sliding grooves at both ends of the brake pads. 4. Use a professional high-temperature anti-seize lubricant. Wear a single-finger glove and apply the product evenly on each tire bolt and the metal contact surface between the wheel rim and the hub.
The most common reason for the car pulling to one side when braking is uneven tire pressure on both sides. Uneven tire pressure causes the car to veer towards the side with lower pressure during braking due to reduced friction. I remember once my car had this issue, and after checking, I found the left front tire was significantly underinflated. Topping it up fixed the problem. Uneven tire tread wear can also cause pulling—if one tire is worn out while the other side is fine, the car will deviate when braking. I make it a habit to check all tire pressures monthly with a simple gauge to keep them consistent. Ignoring this can lead to suspension system issues over time, costing more in the long run. Pay extra attention to this when driving on bumpy roads—safety first. Regular maintenance prevents major problems, so don't wait until it's too late to regret.
