Brakes

Rear brakes wearing faster than front

Rear brakes wearing out faster than the fronts is unusual on most vehicles, since front brakes typically do more of the work, and often points to a parking brake or proportioning issue.

Symptoms

  • Rear pads or shoes worn significantly more than front ones at a similar mileage
  • Possible parking brake that doesn't fully release
  • Rear wheels may run hotter than fronts after driving

Likely causes

  • CommonParking brake not fully releasing, causing constant rear dragEven slight engagement adds continuous wear to the rear brakes.
  • CommonStuck rear caliper or wheel cylinderPrevents full release after braking, wearing that side's brake faster.
  • PossibleBrake proportioning valve issue sending too much pressure to the rearMore common on older vehicles without full electronic brake distribution.
  • Less commonHeavy rear-loaded driving (towing, cargo) shifting brake demand rearwardWorth considering if the vehicle is regularly loaded heavily in the back.

What to do

  1. Check that the parking brake fully releases and doesn't drag even slightly.
  2. Feel the rear wheels for excess heat after a short drive.
  3. Check rear pad or shoe thickness compared to the front.
  4. Have a mechanic inspect rear calipers or wheel cylinders for sticking.
  5. Have the parking brake mechanism or proportioning system checked if calipers test fine.
  6. Have any stuck component repaired or replaced, along with new rear pads or shoes.
