Uneven brake pad wear is commonly attributed to factors related to the brake caliper and its operation. Misalignment refers to the improper positioning of components that can lead to uneven pressure applied to the brake pads when the brakes are engaged. If a caliper is not properly aligned with the rotor, it can result in one side of the pad applying more force than the other, thereby causing that side to wear down faster.

Lack of lubrication can also contribute to this issue. Brake components, especially slide pins, need to be adequately lubricated to allow for free movement. If they bind or stick due to insufficient lubrication, one brake pad may be forced to work harder than the other, leading to uneven wear patterns.

Sticking calipers play a significant role as well. When a caliper is stuck due to corrosion or debris, it may not release completely after braking, leading to continuous contact between the brake pad and rotor on one side, resulting in accelerated wear of that pad compared to the other.

In contrast, the other options typically do not lead to uneven wear as directly as misalignment, lack of lubrication, or sticking calipers. For instance, improper brake pad material may lead to different performance characteristics, but it does not necessarily result in uneven wear
