Symptoms
- Steering wheel or whole car pulls to one side only when braking
- No pulling when driving normally without braking
- Possibly uneven tire wear on one side
Likely causes
- CommonStuck or seized brake caliper on one sideA caliper that doesn't release fully causes that wheel to brake harder or drag.
- CommonUneven brake pad wear side to sideOne side wearing faster reduces its braking force compared to the other.
- PossibleContaminated brake pad (oil or grease) on one sideReduces friction on that wheel only, causing an imbalance.
- PossibleUneven tire pressure or tire wearCan mimic a brake pull even when the brakes themselves are fine.
- Less commonCollapsed brake hose restricting fluid flow to one wheelA hose can collapse internally and act like a one-way valve.
What to do
- Check and equalize tire pressure on all four tires first, since this is quick and can be the whole cause.
- Look at each front tire for uneven wear patterns that might explain a pull.
- Check for a burning smell or extra heat coming from one wheel after driving, which suggests a dragging caliper.
- Compare pad thickness side to side if visible through the wheel spokes.
- Have a mechanic inspect calipers, pads, and brake hoses on both sides.
- Have the sticking caliper serviced or replaced, along with pads if unevenly worn.
- Get an alignment check afterward if the pulling was significant, since it can affect tire wear too.

When to call a pro
See a mechanic to check for a stuck caliper or uneven pad wear, since this can worsen and affect handling during hard stops.
Safety
Use caution
A strong pull while braking can pull you into another lane unexpectedly; get it checked soon and avoid hard braking until then.
