A common symptom of a stuck brake caliper is that the vehicle pulls to one side while braking. When a caliper becomes stuck, it may not apply pressure evenly across the brake pads on that wheel. This uneven pressure can cause the vehicle to steer towards the side with the stuck caliper, especially noticeable during braking.

In a healthy braking system, the calipers should operate symmetrically, allowing equal force to be applied to both sides of the vehicle. Sticking can lead to one side experiencing more friction, effectively causing the other side to have less stopping power, resulting in the noticeable pull to one side.

The other options describe outcomes associated with an evenly functioning brake system. For instance, uniform brake wear and even brake pad wear are signs of proper caliper function, where the same amount of pressure is applied across all wheels. A stiff brake pedal often indicates issues such as air in the brake lines or a malfunctioning master cylinder rather than a caliper problem. Thus, pulling to one side is the definitive symptom indicative of a stuck brake caliper.
