Brakes

Dragging brakes, car won't coast normally

If the car feels like it's constantly fighting to move, doesn't coast freely when you let off the gas, or seems to lose speed faster than normal, one or more brakes may be dragging even when not being pressed.

Symptoms

  • Car feels sluggish or reluctant to coast
  • Noticeably worse fuel economy
  • One or more wheels running hot after driving

Likely causes

  • CommonStuck or dragging brake caliperA caliper that doesn't fully release keeps constant light pressure on the rotor.
  • CommonParking brake not fully releasingEven a partially engaged parking brake creates continuous rear brake drag.
  • PossibleSwollen or degraded brake hose restricting fluid returnTraps pressure in the caliper even after releasing the pedal.
  • Less commonWheel bearing binding, mistaken for brake dragCan feel similar but is a different underlying issue.

What to do

  1. Confirm the parking brake is fully released.
  2. After a short drive, carefully feel each wheel for uneven heat (one noticeably hotter than the rest).
  3. Note if the car feels like it's losing speed faster than usual with no braking input.
  4. Check fuel economy over the past few tanks for a noticeable, unexplained drop.
  5. Have a mechanic check each wheel for free rotation and caliper release with the car safely raised.
  6. Have any dragging caliper, hose, or parking brake component repaired or replaced.
