What are the causes of brake pulling?

[VanParker]

When a car pulls to one side during braking, the reasons may include: uneven wear of brake linings or hub inner rings on one side; uneven tire wear leading to inconsistent friction on both sides; frame deformation causing uneven force distribution; broken load-bearing shock absorbers or oil leakage leading to center of gravity deviation; improperly adjusted brakes with uneven left and right braking force. Specific causes are as follows: Sudden failure in the braking system or suspension components, such as sudden malfunction of one wheel's brake line; Dents in the brake line caused by squeezing or collision, preventing brake fluid or compressed air from passing through; Blockage due to excessive rust or dirt; Sudden movement caused by loose fixing bolts of leaf springs on one side, resulting in misalignment between the front and rear axles and causing brake pulling. Solution: Strictly follow the vehicle inspection requirements before departure and after parking to thoroughly and carefully check the braking system or suspension components. Fault diagnosis and troubleshooting: If the car pulls to the left when braking during driving, it indicates poor braking performance on the right wheel, and vice versa; after braking, check the skid marks of the tires on the road surface, the wheel with shorter or no skid marks is the one with braking issues.

From my years of experience in auto repair, the most common cause of brake pull is uneven tire pressure. When the left tire has low pressure, the car pulls to the left during braking due to asymmetrical friction. Additionally, uneven brake pad wear is prevalent; if one side is thicker and brakes harder, the car will pull in that direction. Suspension components like leaking shock absorbers or loose linkages can affect wheel balance, leading to directional instability during braking. Brake fluid leaks or blocked lines cause uneven brake force distribution on both sides, while ABS sensor malfunctions, though less common, can misjudge braking force. These factors, individually or combined, can cause pulling. I recommend car owners check tire pressure monthly and perform a comprehensive maintenance every six months to ensure driving safety. Don't ignore minor issues—address them promptly to avoid accidents.

As an experienced daily driver, I once encountered the issue of brake pull. The car kept veering to the right, and it turned out the right front brake caliper was seized, causing the brake pads to constantly rub against the rotor. Low tire pressure on the left side exacerbated the problem, and uneven tread wear further increased the friction imbalance. Loose suspension or faulty wheel speed sensors can also cause ABS malfunctions, leading to pulling. After the repair, I developed a habit: paying attention to brake feel while driving and stopping immediately to check if pulling occurs. Safety first—prevention is better than repair, and regular maintenance saves both hassle and money.

Car enthusiasts are well aware of the common issue of brake pull! For instance, after modifying the brake system, if the pressure of the wheel cylinders isn't balanced, one side with excessive braking force can pull the car to that side. Poor tire matching, such as mixing old and new tires or significant differences in tire pressure, is a major cause. Incorrect suspension alignment causing wheels to be out of parallel can exacerbate the issue during braking. A malfunctioning or ineffective ABS module may incorrectly distribute braking force. Maintaining symmetry is key: test brake balance before modifications and regularly check tire pressure to ensure consistency. Don't sacrifice safety for style—careful driving is the ultimate priority.
