Uneven wear can also be a sign of improper brake pad installation or an issue with the brake system’s hydraulic functioning.
Pulling to One Side
If your vehicle pulls to one side when applying the brakes, it can be an indication of uneven brake pad wear. Uneven wear can cause one brake pad to engage more forcefully than the others, resulting in the vehicle veering to one side. This not only affects the vehicle’s stability but can also lead to uneven tire wear, requiring more frequent tire rotations or replacements.
Unusual Tire Wear
Inspecting your vehicle’s tires can provide clues about the condition of the brake pads. Uneven brake pad wear can lead to uneven tire wear, causing certain areas of the tire tread to wear down faster than others. If you notice abnormal tire wear patterns, it is important to have your brake pads and the overall brake system inspected to prevent further damage and ensure optimal performance.
