Brakes Dragging
A brake that does not fully release makes the car feel held back, one wheel run much hotter than the others and often pull to one side; a seized caliper, sticking slide pins or a handbrake that does not release are common causes.
High risk
Have it checked promptly. A dragging brake overheats, wears quickly and can lose braking power.
Short answer · How do I know if my brakes are dragging?
The car may feel as if it is driving through mud, roll less freely, use more fuel and pull to one side. After a drive, one wheel is far hotter than the others and may smell hot. The usual causes are a caliper piston or slide pins seized with corrosion, a handbrake cable that sticks, or a collapsed brake hose that traps pressure.
Safe checks you can do
- Compare wheel heat after a driveHold your hand near each wheel without touching. One much hotter wheel points to the dragging brake.Never touch discs or wheels after driving; they can burn.
- Release the handbrake fullyCheck that it moves freely and the warning light goes out.
- Push the car on level groundWith the engine off and in neutral, a car that is hard to push may have a dragging brake.
