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