A disc brake caliper that is worn or sticking can show up as a pull to one side under braking, uneven pad wear or brake fluid seeping near the piston boot. Before you replace it, rule out worn pads, a swollen brake hose or a seized slide pin, since each of those can make a vehicle pull or drag too.
