When braking, the car will pull toward the side that is braking harder or dragging more than the other. Any condition that creates an imbalance between left and right braking forces can cause a pull in a specific direction.

A seized brake caliper on one wheel keeps the pads pressed against the rotor, causing that wheel to drag and brake harder than the opposite side. That extra drag makes the car pull toward the side with the seized caliper.

If a rotor on one wheel is incorrectly machined or not true, the friction contact on that wheel changes, producing uneven braking forces. The side with the higher effective friction can pull the vehicle toward it during braking.

A leaking axle seal can allow oil or grease to contaminate the braking surface on one wheel, reducing its braking effectiveness. The side with normal braking then dominates, pulling toward the side with better braking.

These scenarios show how brake imbalance during braking can lead to a leftward pull. Worn tires or road crown affect handling more generally and aren’t specifically about unequal braking forces, while low brake fluid reduces overall braking rather than creating a directional pull.
