Car shakes when braking

Fix soon

Book a brake check within the next few days and brake gently until then. If the pedal goes soft, the car pulls hard or you hear grinding, stop driving.

Quick answer

Shaking when you brake is most often caused by brake discs that have worn unevenly, so the pads grip them in pulses. It is usually not an emergency, but braking gets less smooth and the problem grows, so have it checked soon.

Likely causes, most common first

  1. Uneven brake discs

    The disc's thickness varies slightly around its surface, or pad material has stuck to it in patches. Each turn of the wheel, the pads grab harder then softer, and you feel it as a pulse. Fixed by machining or replacing the discs, usually with new pads.

  2. Wheel nuts tightened unevenly

    Common right after a tire change. Uneven torque pulls the disc slightly out of line with the hub, which in time leads to the uneven wear above.

  3. Worn or contaminated brake pads

    Pads that are glazed, oily or worn unevenly grip in an irregular way. Usually replaced together with the discs.

  4. A sticking caliper

    One brake keeps rubbing, overheats its disc and makes it uneven. Often the car also pulls to one side or one wheel smells hot.

  5. Worn suspension or steering parts, or tire problems

    Worn joints, an unbalanced wheel or a bent rim can shake the car anyway, and braking makes it more noticeable. If the shaking is there when you are not braking too, start here.

How to prevent it

  • Have wheel nuts tightened with a torque wrench, in a star pattern, never with an air gun alone.
  • Avoid holding the brakes hard while stopped after heavy braking, such as at the bottom of a long hill.
  • Bed in new pads as the manufacturer describes.
  • Replace pads and discs as a pair on each axle.

Questions drivers ask

Are my brake discs warped?

People often call it "warped rotors", but the discs rarely bend. More often their thickness has become uneven, or pad material has built up in patches. The effect is the same: the pedal pulses and the car shakes.

Steering wheel or seat: does it matter where I feel it?

Yes. A shaking steering wheel usually points to the front brakes. A pulsing you feel through the seat or the whole car points more to the rear.

It only started after new tires were fitted. Why?

If the wheel nuts were tightened unevenly, they can pull the disc slightly out of true. Ask the tire shop to re-torque the nuts to the correct setting; if the shaking stays, the disc may need machining or replacing.

Is it safe to keep driving?

For a short while, gently, in most cases. Stop driving if the pedal feels soft or sinks, the car pulls strongly to one side, or you hear grinding.
