A pull to one side under braking, brake fluid around the caliper or a low pedal can mean a caliper is failing. Before you replace it, rule out a collapsed brake hose, sticking slide pins or air in the system, since those can produce similar symptoms. Both front calipers are normally replaced together. This listing is one caliper for the front left; the car takes one on each side of the front axle, and the front right is ordered separately.
