Common Causes of Uneven Brake Pad Wear on One Side

It’s typical for brakes to wear a bit over time as you drive. But, if one Side’s pads are wearing quicker than the other, it could be a sign of something larger. We’ll examine the most frequent causes of uneven brake pad wear on one Side. Plus, what can you do to repair it?

Worn or Stuck Brake Caliper

Uneven brake pad wear on one side is a significant safety issue. It can affect your vehicle’s braking system. The leading cause is a worn or stuck brake caliper.

A brake caliper presses the brake pads against the rotor. This creates the friction needed to slow down or stop. When a caliper gets stuck, it doesn’t put equal pressure on the pads. This causes one place to wear faster than the other. Worn calipers could also stop the places from fully retracting. This leads to excess heat and uneven wear.

Other causes of one-sided brake pad wear include worn suspension parts, damaged brake hardware, and hydraulic problems. If you hear squeaking or your car pulls to one side while braking, take it to a mechanic. Regular maintenance can stop these issues and keep you safe.

Pro tip: Inspect your vehicle regularly to prevent uneven brake pad wear and stay safe on the road.

Loose or Broken Suspension Component

Does uneven brake pad wear on one Side? Loose or broken suspension components could be the cause. Wheels tilt, and that causes uneven wear.

Other common causes:

  • Sticking Caliper – Uneven wear.
  • Unlubricated Slides – Uneven wear.
  • Uneven Rotor – Uneven wear.
  • Worn Bearings – Uneven wear.

Address mechanical issues fast. Safety first.

Pro Tip: Regular maintenance and inspections help detect more significant problems.

Failed Wheel Bearing

Does uneven brake pad wear on one Side? It could be a failed wheel bearing! This produces heat and can damage the braking system.

But there’re other causes too. These could be:

  • I have worn suspension parts such as bushings, ball joints, or springs. This misaligns the suspension, leading to uneven brake pad wear.
  • I am sticking calipers. If these don’t move freely, the brake pad wears unevenly.
  • Brake hose collapse. This restricts brake fluid flow, resulting in uneven braking pressure.

Pro Tip: If you spot uneven brake pad wear on one side, have a professional mechanic inspect it. This’ll diagnose the problem and avoid further damage.

Malfunctioning ABS Sensor

Does uneven brake pad wear on one Side? Many things can cause that. One of them is an ABS sensor malfunction. The ABS sensor keeps track of each wheel’s speed and stops skidding during braking. When it fails, the brake pad on one side wears out faster.

Other usual causes of this are:

  • a sticky caliper,
  • worn suspension parts,
  • and misaligned wheels.

Pro Tip: If you spot uneven brake pad wear on one side, take it to a reliable mechanic. They’ll inspect it and fix the problem so you can drive safely.
